The material, width, or thickness of the band portion 51 and the material or type of the buckle 52 are not particularly limited, and may be appropriately selected depending on the size and weight of the laminate 2. Examples of the band portion 51 include a resin material such as a PP band, and a cloth material.

Using the laminate 2, contact suppression member 3, protection plate 4, and fixing member 5 as described above, the object to be packed 1 is manufactured as follows.
Note that the following work may be entirely performed by the device or manually by the worker, or may be partially performed by the device or the worker. Also, multiple tasks may be performed simultaneously.

First, the contact suppression member 3 is placed on the protection plate 4. It is preferable that the contact suppression member 3 is placed such that its center overlaps the center of the protection plate 4 and its entire outer edge is located inside the outer edge of the protection plate 4.
Furthermore, a plurality of laminates 2 and contact suppressing members 3 are placed on the contact suppressing member 3 in this order. At this time, the laminate 2 is placed so that the entire outer edge of the laminate 2 is located inside the outer edge of the protection plate 4. In addition, it is preferable that the laminated body 2 and the contact suppression member 3 are mounted so that the center may overlap the center of the protection plate 4. In addition, the number and weight of the laminate 2 are not particularly limited, but the inertia force when the object to be packed 1 is conveyed in the plane direction of the plate-like base 21 and stopped, or when the object to be packed 1 is placed vertically (When placed so that the surface direction of the plate-shaped substrate 21 is parallel to the vertical direction) The laminate 2 does not shift relative to the protective plate 4 due to gravity, or even if it shifts, the second protective film It is preferable that the entire outer edge of the protective plate 23 be set so as not to be located outside the outer edge of the protection plate 4.

Furthermore, a protection plate 4 is placed on the topmost contact suppression member 3.

Place it on top. Note that the protection plate 4 is preferably placed so as to overlap the protection plate 4 located below the laminate 2 in plan view.

Next, the first and second rubber bands 5A and 5B are wrapped around the laminate 2, the contact suppression member 3, and the protection plate 4. At this time, as shown in FIG. 2, the first rubber band 5A is hung so that the angle θ1 between the longitudinal direction of the first rubber band 5A and the ridgeline direction shown by the two-dot chain line is 0° or more and 30° or less. turn. In this embodiment, as shown by the solid line in FIG. 2, the first rubber band 5A is attached to the protection plate 4 so that the longitudinal direction is parallel to the short side direction of the protection plate 4, that is, θ1 is 0°. Hang it around the center of the long side. Further, the second rubber band 5B is hung around so that the angle θ2 between the longitudinal direction of the first rubber band 5A and the longitudinal direction of the second rubber band 5B is greater than or equal to 50° and less than or equal to 90°. In this embodiment, the second rubber band 5B is wrapped around the center of the short side of the protection plate 4 so that the longitudinal direction is parallel to the long side direction of the protection plate 4, that is, θ2 is 90°. .
The total tension of the first and second rubber bands 5A, 5B stretched as described above is preferably 10N or more and 80N or less.
If it is less than 10 N, the fixing force will be insufficient and the laminate 2 will shift. If the force exceeds 80N, there is a risk that the protection plate 4 may be bent or the protection plate 4 may come into strong contact with the first and second rubber bands 5A, 5B, resulting in damage to the protection plate 4. The total tension of the first and second rubber bands 5A, 5B is more preferably 15N or more, and even more preferably 20N or more. The total tension of the first and second rubber bands 5A, 5B is preferably 60N or less, more preferably 50N or less.

Therefore, as shown in FIG. 4, even if the second rubber band 5B is hung around so that the angle between its longitudinal direction and the ridgeline 41A is 90°, its geometric rigidity effect will cause the protective plate 4 It is possible to suppress the portion located on the outside of the plate-like base body 21 from greatly bending along the ridge line 41A.
Through the above operations, manufacturing of the object to be packed 1 is completed.

As shown in FIG. 3, when using the tightening bands 50, first, the band portions 51 of the two tightening bands 50 are separated by a predetermined distance and placed on a workbench so as to be parallel to each other. Place plate 4. At this time, similarly to the first rubber band 5A, it is placed so that the angle between the ridgeline direction and the longitudinal direction of the band portion 51 is 0° or more and 30° or less.
Thereafter, as in the case of using the first and second rubber bands 5A and 5B, the laminate 2, the contact suppression member 3, and the protection plate 4 are placed, and the band portion 51 is connected to the laminate 2, the contact suppression member 3, and the protection plate 4. It is hung around the board 4 and fixed at both ends using buckles 52. Thereafter, the band portion 51 is tightened by pulling the end portion 51A of the band portion 51 on the side where the buckle 52 is not provided from the position shown by the two-dot chain line to the position shown by the solid line in FIG. The total tension of the band portion 51 is preferably 10N or more and 80N or less.

At this time, the first side portion 4A of the protection plate 4 that is not in contact with the band portion 51 is not deformed as shown in FIG. 6. Further, since the first side portion 4A is not deformed, the portions of the contact suppression member 3 and the second protective film 23 on the first side portion 4A side are also hardly deformed.
On the other hand, the protection plate 4 in contact with the band portion 51 is slightly bent along a line parallel to the ridgeline 41A of the core 41 due to the winding force of the band portion 51, as shown in FIG. Due to this deflection of the second side portion 4B, the portions of the contact suppression member 3 and the second protective film 23 on the second side portion 4B side are slightly bent along the outer edge of the plate-like base 21.

Therefore, when the object to be packed 1 is housed in the bag body 11, the bag body 11 is arranged so as to span the outer edges of the pair of protection plates 4, and the bag body 11 and the first and second A gap can be formed between the outer edges of the second protective films 22 and 23. Therefore, rubbing between the bag 11 and the first and second protective films 22 and 23 can be suppressed, and particles caused by the rubbing can be prevented from adhering to the plate-like substrate 21.

Since the protection plate 4 is fixed to the laminate 2 by the fixing member 5, it is possible to suppress misalignment of the laminate 2 with respect to the protection plate 4 when the object to be packed 1 is transported.
In particular, since the first and second rubber bands 5A and 5B are used as the fixing member 5, the first and second rubber bands 5A and 5B can be easily attached to the laminate 2 and the protection plate 4 by simply wrapping them around the laminate 2 and the protection plate 4. can be fixed.

The winding force of the first and second rubber bands 5A and 5B causes the ends of the second protective film 23, the contact suppression member 3, and the protective plate 4 to bend along the outer edge of the plate-like base 21, so that the bending causes It is possible to suppress misalignment of the laminate 2 in the left-right direction in FIGS. 4, 5, and 7.
In addition, when using the tightening band 50, since the angle between the ridgeline direction of the center 41 of the protection plate 4 and the longitudinal direction of the band portion 51 is 0°, the second side portion 4B of the protection plate 4 It is bent along a line perpendicular to the ridgeline 41A. Therefore, the breakage of the protection plate 4 can be suppressed compared to the case where the first side portion 4A of the protection plate 4 is bent along the ridge line 41A.

Since the corners of the protection plate 4 are formed at obtuse angles in plan view, it is possible to prevent the corners of the protection plate 4 from damaging or cutting the bag body 11.

Since the contact suppressing member 3 is provided between the laminate 2 and the protection plate 4 or between the laminate 2, the laminate 2 will not touch the protection plate 4 or other laminates when the object to be packed 1 is being transported or placed vertically. It is possible to suppress slipping relative to the body 2. Therefore, particles generated due to friction between the bag 11 and the first and second protective films 22 and 23 may adhere to the plate-like base 21, or the plate-like base 21 may collide with the floor or the like and be damaged. can be suppressed.

Further, the contact suppressing member 3 may be arranged between the plate-shaped substrates 21 and between the first protective film 22 or the second protective film 23 and the plate-shaped substrate 21.

The corners of the protection plate 4 may be curved in plan view, and the overall shape of the protection plate 4 may not be octagonal as long as they are obtuse angles. Even in this case, it is possible to prevent the corners of the protection plate 4 from damaging or cutting the bag body 11.
The corners of the protection plate 4 may be at right angles or acute angles in plan view, and in this case, it is preferable that the housing member that contacts the protection plate 4 has a configuration that will not be damaged or cut by the contact.
At least one of the pair of protection plates 4 may be made of a material that does not deform, or may not have a corrugated cardboard structure.
The protection plate 4 may be positioned such that the angle between the ridgeline direction and the longitudinal direction of the band portion 51 is 90°, and in this case, when the protection plate 4 is bent along the ridgeline direction. In addition, it is preferable to have a structure that does not break.
Furthermore, when the plate-like base 21 is curved, the protection plate 4 may have a curved shape along the shape of the laminate 2, as shown in FIG. By doing so, displacement of the plate-like substrate 21 can be suppressed more effectively. Note that such a protection plate 4 can be produced, for example, by molding a foamed resin sheet.
The end portion of the protection plate 4 may be bendable. As shown in FIG. 9, by bending the end portion of the protection plate 4, contact between the plate-like base body 21 and the bag body 11 can be further suppressed. Further, in such a case, when placing the plate-like substrate 21, it is possible to bend the end of the protection plate 4 after placing the plate-like substrate 21 without bending the end of the protection plate 4. preferable. Furthermore, when placing the plate-like substrate 21, holding the side surface of the laminate 2 may cause the protective film 22 to turn over or rub, so it is best to hold the main surface of the laminate 2 by suction or by sandwiching it. is preferred. In such a case, when placing the plate-like substrate 21, the laminates 2 can be stacked laterally. If the ends of the protective plate 4 are bent after the plate-shaped substrate 21 is placed in order to protect the side surfaces of the laminate 2, adhesion of particles to the plate-shaped substrate 21 can be further suppressed.

It is not necessary to wrap the first rubber band 5A or the second rubber band 5B, or another rubber band may be placed next to the first rubber band 5A or the second rubber band 5B.
Although the tightening band 50 is constituted by a tightening belt having a band portion 51 and a buckle 52, it may be constituted by a band-shaped or string-shaped wrapping member, and both ends of the wrapping member may be tied, glued, or fused. It may also be fixed by
Adhesive tape may be used as the fixing member.

[Modified example of packaging]
Although the object to be packed 1 housed in the bag body 11 is housed in the box body 12, it does not have to be housed in the box body 12, and in this case, the weight and cost of the package can be reduced.
The bag body 11 may be made of paper or cloth, and even in this case, the protection plate 4 can suppress the rubbing between the bag body 11 and the first and second protective films 22 and 23, and prevent the damage caused by the rubbing. It is possible to prevent particles from adhering to the plate-like substrate 21. Alternatively, the bag 11 may be configured by wrapping a sheet-like member made of resin, paper, or cloth around the object to be packed 1.
The object to be packed 1 may be directly stored in the box 12 without being stored in the bag 11, and in this case, the box 12 corresponds to the storage member of the present invention.

[Other variations]
<Plate-shaped substrate>
The use of the plate-like substrate of the present invention is not particularly limited. Specific examples include transparent parts for vehicles (headlight covers, side mirrors, front transparent substrates, side transparent substrates, rear transparent substrates, instrument panel surfaces, etc.), meters, architectural windows, show windows, architectural interior parts, Architectural exterior parts, displays (laptop computers, monitors, LCDs, PDPs, ELDs, CRTs, PDAs, etc.), LCD color filters, touch panel substrates, pickup lenses, optical lenses, eyeglass lenses, camera parts, video parts, CCDs Cover substrates, optical fiber end faces, projector parts, copier parts, transparent substrates for solar cells (cover glass, etc.), mobile phone windows, backlight unit parts (light guide plates, cold cathode tubes, etc.), backlight unit parts LCD brightness improvement Films (prisms, semi-transparent films, etc.), LCD brightness enhancement films, organic EL light emitting device parts, inorganic EL light emitting device parts, phosphor light emitting device parts, optical filters, end faces of optical parts, lighting lamps, covers for lighting equipment, amplification Examples include laser light sources, antireflection films, polarizing films, and agricultural films.
The shape of the plate-like substrate is not particularly limited, and examples thereof include a disk, an elliptical plate, a triangular and pentagonal polygonal plate, and the like.

Examples of the plate-like substrate include common glass plates such as soda lime glass, borosilicate glass, aluminosilicate glass, and alkali-free glass, inorganic glasses made of inorganic materials of various compositions, and transparent resin plates. .
Optimal materials for the glass plate include glass materials such as soda lime glass, quartz glass, crystal glass, and sapphire glass, with high transmittance glass having a lower iron content and less blue tint being more preferred.
As the material for the transparent resin plate, highly transparent resin materials are preferred, such as polyester resins such as polycarbonate, polyethylene terephthalate, polyolefin resins such as polypropylene, polyvinyl chloride, acrylic resins, polyether sulfone, and polyester resins. Examples include arylate, triacetyl cellulose, polymethyl methacrylate, and the like.

As the plate-like substrate, a glass plate is most preferable also because it has high transparency, light resistance, heat resistance, low refractive index, high planar accuracy, surface scratch resistance, and high mechanical strength.
In order to increase the safety of the glass plate, the mechanical strength may be increased. In order to increase the mechanical strength of a glass plate, the glass plate is subjected to a strengthening treatment in advance.
Strengthening treatments include physical strengthening, in which the glass plate is exposed to high temperatures and then air-cooled, or the glass plate is immersed in molten salt containing an alkali metal, which strengthens the alkali with a small atomic diameter that exists on the outermost surface of the glass plate. Chemical strengthening involves replacing metals (ions) with large atomic alkali metals (ions) present in molten salt.

In particular, when using a thin glass plate, it is preferable to use a chemically strengthened glass plate (hereinafter also referred to as "chemically strengthened glass").
It is preferable that the chemically strengthened glass used as the plate-like substrate satisfy the following conditions. That is, the surface compressive stress (hereinafter referred to as CS) of the glass substrate is preferably 400 MPa or more and 1200 MPa or less, more preferably 700 MPa or more and 900 MPa or less. If CS is equal to or higher than the lower limit value, the strength is sufficient for practical use.
Moreover, if CS is below the upper limit, it can withstand its own compressive stress and there is no fear that it will spontaneously break. When the plate-like substrate of the present invention is used as a front plate (cover glass) of a display device or the like, the CS of the glass substrate is preferably 700 MPa or more and 850 MPa or less.

Furthermore, the depth of stress value (hereinafter referred to as DOL) of the glass substrate is preferably 15 μm to 50 μm, more preferably 20 μm to 40 μm. If DOL is equal to or higher than the lower limit value, there is no fear that it will be easily damaged and destroyed.
Further, if the DOL is below the upper limit value, the substrate can withstand its own compressive stress and there is no fear that it will spontaneously break. When the plate-like substrate of the present invention is used as a front plate (cover glass) of a display device or the like, the DOL of the glass substrate is preferably 25 μm or more and 35 μm or less.

Furthermore, sapphire glass is also preferred from the viewpoint of mechanical strength.

The shape of the plate-like substrate is usually smooth and rectangular. The shape of the plate-like substrate is appropriately changed depending on the shape of the display panel of the display device, the design of the display device, the mounting position of the display device, and the like.
That is, the shape of the plate-like substrate is not limited to a smooth shape or a rectangular shape. For example, it may be a template glass having an uneven surface, or may have a polygonal shape, a circular shape, or an elliptical shape. Moreover, not only flat glass but also glass having a curved shape may be used.

The size of the plate-like substrate is appropriately determined depending on the size of the display panel and the purpose of the display device. For example, when used as a cover glass for mobile devices, the size should be 30 mm x 50 mm to 300 mm x 400 mm, and the thickness should be 0.1 mm or more and 2.5 mm or less, and it should be used as a cover glass for display devices, car navigation, console panels, instrument panels, etc. In the case of a device, the size is preferably 50 mm x 100 mm to 2000 mm x 1500 mm, and the thickness is preferably 0.5 mm or more and 4 mm or less.

The thickness of the plate-like substrate is not particularly limited, and glass having a thickness of 10 mm or less can be used. In terms of mechanical strength and transparency, the thickness of a glass plate is usually about 0.1 mm to 6 mm. In particular, when used in an on-vehicle display device, safety is required for the plate-like substrate, so from the viewpoint of mechanical strength, the thickness is preferably 0.2 mm or more and 2 mm or less.
When chemically strengthened glass is used, the thickness of the glass substrate is usually preferably 5 mm or less, more preferably 3 mm or less, in order to effectively perform chemical strengthening treatment. In the case of a transparent resin plate, the thickness is preferably 2 mm or more and 10 mm or less.
Since the thinner the thickness, the lower the light absorption can be suppressed, it is preferable to use a glass plate from the viewpoint of improving visibility and transparency. Note that the plate-like substrate is not necessarily limited to a single layer structure composed of a single layer, but may have a multilayer structure composed of a plurality of layers such as laminated glass.

<Protective film>
In order to protect the display panel assembled in the display device during the manufacturing process and product transportation, a first protective film is attached to the plate-shaped substrate to protect the plate-shaped substrate.
When using the display device, the first protective film is peeled off from the plate-like substrate and used.
Either surface of the protective film has an adhesive layer. Examples of the adhesive force include adhesive force, van der Waals force, and electrostatic force, but adhesive force is preferable from the viewpoint of easy peelability from the plate-like substrate and cost, and it is preferable that the protective film has an adhesive layer.
By adjusting the adhesive force of the adhesive forming the first adhesive layer, the adhesive can be applied to at least the outermost surface (the first main surface or the antireflection layer, antifouling layer, or other functional layer) of the plate-like substrate. It is possible to prevent the antireflection layer from remaining in some areas and from peeling off at least a portion of the antireflection layer or the antifouling layer.

Furthermore, in order to increase the ease of peeling of the protective film, it is possible to separate the first protective film from the second protective film or plate-shaped substrate by providing a portion on which no adhesive layer is formed on at least a part of the outer periphery of the protective film. It can be easily peeled off. Note that the tab portion produced for the purpose of facilitating the above-mentioned peelability may protrude to the outer periphery within a range that does not impair handling properties.

When laminating a protective film to a plate-like substrate provided with an antireflection layer or an antifouling layer, it may be done manually, but the protective film supplied as a roll may be laminated using a rubber roll or the like. In addition, from the viewpoint of production efficiency, it is preferable to cut the protective film into sheet films in advance according to the dimensions of the plate-like substrate, and then laminate them using a labeling machine or a sealing machine.

<Film>
The film is not particularly limited as long as it is made of resin and in the form of a film. Further, the film may have a single layer structure or a multilayer structure in which a plurality of layers such as an antistatic layer, a hard coat layer, and an easily bonding layer are laminated. Further, in order to prevent forgetting to remove the protective film from the plate-like substrate, a part or the entire surface of the film may be colored or a sticker may be attached.

As the film, for example, a polyester film such as polyethylene terephthalate, a polyethylene film, a polyolefin film such as polypropylene, a polyvinyl chloride film, etc. can be used. Among these, polyester films are preferred from the viewpoint of adhesion to the adhesive layer, durability, and optical properties.

The thickness of the film is also not particularly limited. The thickness of the film is, for example, preferably 5 μm or more and 100 μm or less, and more preferably 15 μm or more and 75 μm or less because the film is easily bent and peeled when peeled. If the thickness is less than 5 μm, the plate-like substrate may not be sufficiently protected, and if it exceeds 100 μm, the cost may increase.

<Adhesive layer>
The adhesive of the adhesive layer preferably has a tackiness that makes it difficult for the adhesive to remain on at least a portion of the outermost surface of the plate-shaped substrate when the protective film is peeled off from the plate-shaped substrate. The adhesive of the adhesive layer preferably has a tackiness that suppresses peeling of at least a portion of the antireflection layer or the antifouling layer when the protective film is peeled off from the plate-like substrate.
As such an adhesive, an acrylic adhesive, a polyurethane adhesive, or the like is preferably used from the viewpoint of adhesiveness and removability.

When the adhesive force of the adhesive layer is 0.01 N/10 mm or more, the adhesive can be uniformly attached to the outermost surface of the plate-like substrate, and the adhesive layer can be uniformly attached to the antireflection layer or the antifouling layer. In addition, there is no risk of the film peeling off from the plate-like substrate during transportation, and thus impairing its function as a film.
If the adhesive force of the adhesive layer is 0.3 N/10 mm or less, the adhesive force of the adhesive layer is appropriate, and at least a part of the antireflection layer or the antifouling layer will be peeled off more than necessary when the protective film is peeled off. Furthermore, there is no risk of defects such as reduced visibility or stains caused by the adhesive remaining on at least a portion of the outermost surface of the plate-like substrate.

Examples of the present invention will be described. Examples 1 to 5 are examples, and example 6 is a comparative example. Note that the present invention is not limited to the following examples.

[Preparation of package]
[Example 1]
As a plate-shaped substrate, a chemically strengthened glass (unstrengthened Dragon Trail (registered trademark), manufactured by Asahi Glass Co., Ltd. (denoted as "DT" in Table 1) with a thickness of 1.3 mm and a planar view size of 120 mm x 280 mm) was used. ) was prepared.
As the first protective film, a type A film (manufactured by Nitto Denko Corporation, model number RP-207) consisting of a PET film base having a size of 118 mm x 278 mm in plan view and an adhesive layer was prepared.
As the second protective film, a Type A film was prepared in which the size of the film base in plan view was 125 mm x 285 mm. The coefficient of static friction between the protective films is 0.08.

Miramat (registered trademark), which is a highly foamed polyethylene sheet, was prepared as a contact suppression member. The coefficient of static friction between the contact suppression member and the protective film was 0.6.
As a protective plate, a type A type (antistatic plastic cardboard) made of plastic and having an octagonal plate shape similar to the above embodiment was prepared. The size of the protection plate in plan view is 170 mm x 330 mm. The protective plate has a corrugated structure with liners provided on both sides of the core, and has a total thickness of 3 mm. The flexural modulus is 35 N/cm.
Two rubber bands (rubber band #180 manufactured by Kyowa Co., Ltd.) similar to those in the above embodiment were prepared as fixing members.
As a storage member, a vinyl gusset bag (gusset type PE bag manufactured by Plus Wrapping System Co., Ltd.) was prepared.

First, the first and second protective films were bonded to the first and second main surfaces of the plate-like substrate to produce a laminate. At this time, the outer edge of the first film base of the first protective film is located 1 mm inside the outer edge of the plate-like base, and the second protective film is located 2 mm further inward than the plate-like base over its entire outer circumferential direction. A laminate was produced so that the protective films protruded outward by .5 mm and the end regions of both protective films did not come into close contact with each other (so that the end surfaces of the plate-shaped substrate were not protected). Further, a tab was attached to the first film so as to protrude 1 mm outward from the plate-like substrate.
Next, after placing the contact suppression member on the protection plate, 25 laminates and 25 contact suppression members were placed in this order. Furthermore, a protection plate was placed on the uppermost contact suppression member. At this time, the centers of the protection plate, the contact suppression member, and the laminate were made to overlap in plan view. Further, the protective plate was made to protrude 25 mm outward from the plate-shaped base over the entire outer circumferential direction.

Then, using the first rubber band (Rubber band #180 manufactured by Kyowa Co., Ltd.), wrap it around the center of the long side of the protective plate in the direction of the short side, and use the second rubber band (Rubber band manufactured by Kyowa Sha Co., Ltd.). A band (number: #270) was wrapped around the center of the short side of the protective plate in the long side direction. The tension of the first rubber band at that time was 12N, and the tension of the second rubber band was 11N.
Then, the objects to be packed produced as described above were housed in a gusset bag to produce a package. At this time, when viewed from the side, the gusset bag was arranged to span the outer edges of the upper and lower protection plates in a substantially straight line.

[Example 2]
As a protection plate, type B (polypropylene triple foam sheet manufactured by Mitsui Chemicals Tohcello Co., Ltd., product name: Paronia (registered trademark)) was used, and the number of rubber bands (manufactured by Kyowa Co., Ltd., rubber band #180) was set to 2. Two rubber bands were wrapped around the protective plate, the contact suppression member, and the laminate so that the longitudinal direction was parallel to the short side direction of the protective plate and 50 mm apart. The tension of each rubber band at that time was 12N.
The material of the type B protection plate is a polypropylene (PP) triple foamed sheet, the shape in plan view is dodecagonal, and the size is 170 mm x 330 mm. The flexural modulus is 300 N/cm. The overall thickness of the protective plate is 5 mm.
The object to be packed thus produced was housed in a gusset bag under the same conditions as in Example 1 to produce a package.

[Example 3]
As the first protective film of the plate-shaped substrate, a type B film (manufactured by Nitto Denko Corporation, model number RB-100S) made of PE was used, and a type B film made of the same material as type A but with a thickness of 2 mm was used as the protective plate. C. was used. The flexural modulus is 12 N/cm. A tightening band having a band portion made of polypropylene was used as the fixing member. The coefficient of static friction between the protective film and the contact suppression member was 0.3.
The size of the type B protective film in plan view is 154 mm x 284 mm.
The shape of the Type C protection plate in plan view is a rectangle having an R portion of 10 mm, and the size is 170 mm x 330 mm.
First, two tightening bands were arranged 50 mm apart, and the same number of protection plates, contact suppression members, and laminates as in Example 1 were placed thereon in the same manner as in Example 1. At this time, the center between the two tightening bands and the center of the laminate overlapped, and the angle between the ridgeline direction of the center of the protection plate and the longitudinal direction of the band portion was 0°.
Thereafter, both ends of the band portion were fixed with buckles on the upper protection plate, and the end of the band portion on the side where the buckle was not provided was pulled to tighten the protection plate, the contact suppression member, and the laminate. At this time, the tension of each tightening band was set to 20 N, so that the protective plate, the contact suppression member, and the protective film were bent along the outer edge of the plate-like substrate.
The object to be packed thus produced was housed in a gusset bag under the same conditions as in Example 1 to produce a package.

[Example 4]
As the plate-like substrate, a DT having a size of 280 mm x 140 mm in plan view and uniformly curved concavely in the short side direction with a radius of curvature of 1000 mm was used. Furthermore, a type A protective film was used, and the size was 284 mm x 144 mm in plan view. Otherwise, a packaged object was produced under the same conditions as in Example 1. Then, this object to be packed was housed in a gusset bag under the same conditions as in Example 1 to produce a package.

[Example 5]
A packaged object was prepared under the same conditions as in Example 1, except that a single rubber band (rubber band #270 manufactured by Kyowa Co., Ltd.) was used as the fixing member and was wrapped around the center of the short side of the protection plate. The tension of the rubber band at that time was 7N. Then, this object to be packed was housed in a gusset bag under the same conditions as in Example 1 to produce a package.

[Example 6]
A packaged object having only 26 stacked contact suppressing members and 25 laminates was produced in the same manner as in Example 1 without using a protective plate or a fixing member. Then, this object to be packed was housed in the same gusset bag as in Example 1 to produce a package.

[evaluation]
[Particle evaluation]
The package of Example 1 was placed on a trolley and moved on an asphalt ground for 20 minutes. Then, the objects to be packaged were removed from the gusset bag, and the end surfaces of the 25 plate-shaped substrates were irradiated with a green lamp to check whether particles caused by friction between the gusset bag and the protective film were attached to the end surfaces of the plate-shaped substrates. I visually checked to see if this was the case. The packages of Examples 2 to 6 were also evaluated in the same manner.

As shown in Table 1, in the packages of Examples 1 to 5 in which the laminate was arranged between a pair of protective plates, no particles were attached to the end surfaces of any of the plate-like substrates (evaluation A). In the package of Example 6 in which no plate was used, there was a plate-like substrate with particles attached to the end face (rating C).
The reason why Examples 1 to 5 were rated A is that the pair of protective plates creates a gap between the gusset bag and the protective film, which suppresses the friction between the gusset bag and the protective film and generates particles. This is probably because they did not. On the other hand, the reason why the evaluation was C in Example 6 is that because there is no pair of protective plates, the gusset bag and the protective film rub against each other, generating particles, and the generated particles pass between the pair of protective films. This is thought to be because the particles reached the plate-like substrate.
Therefore, by sandwiching the laminate between a pair of protective plates and positioning the entire outer edges of the pair of protective plates outside the outer edge of the laminate, it is possible to suppress the friction between the gusset bag and the protective film. It was confirmed that it was possible to suppress the adhesion of particles to the plate-like substrate due to this.

[Vibration resistance evaluation]
The packaged body of Example 1 was placed on a trolley and moved on asphalt ground for 20 minutes, and then the packaged body was removed from the gusset bag and the alignment of the plate-shaped substrates was confirmed. As shown in FIG. 10, the alignment condition is evaluated by comparing the outer edge of the plate-like substrate 21 whose outer edge is located closest to the center of the protection plate 4 and the outer edge of the plate-shaped substrate 21 whose outer edge is located closest to the outer edge of the protection plate 4. Evaluation was performed using the amount of deviation A, and those with a deviation amount A of 10 mm or more were evaluated as having no earthquake resistance (evaluation C), and those with the deviation amount A of less than 10 mm were evaluated as having earthquake resistance (evaluation A).
Similar evaluations were conducted for Examples 2 to 6 as well.

As shown in Table 1, the evaluation was A for the packages of Examples 1 to 4 in which the total tension of the fixing members was 23 N or more, but when the packages in Example 5 and the fixing members in which the total tension of the fixing members was 7 N or less were used. In Example 6, which was not used, the evaluation was C.
From this, it was found that when the total tension of the fixing members was 20 N or more, the displacement of the substrate due to vibration during transportation was further reduced.
Furthermore, even with the same evaluation of A, the amount of deviation in Examples 1 and 3 was particularly small. It is presumed that this is because the tension in Example 3 was sufficiently high. In Example 1, it is assumed that this is because the wires are crossed and turned around, making it difficult to move in all four directions. Considering the ease of hanging, it was found that Example 1 could most efficiently suppress particles and substrate displacement.
