Description

  The present invention relates to a technique for repairing a resin film material.

  There is known a resin film material in which both surfaces of a base fabric formed by weaving yarn are covered with a resin layer made of resin. Such a resin film material has unique characteristics that are superior to other materials, such as lightness, translucency, width of the shape that can be made by it, beauty, etc., depending on the object. For example, it is used as a building material.

When a resin film material is used as a building material, the period of use may exceed 10 years and extend to 20 years or more. Then, the resin film material may be damaged due to such long-term use or contact of flying objects due to strong winds or the like. Regardless of whether or not the resin film material is used as a building material, when the resin film material is damaged, it is necessary to repair the resin film material.
Conventionally, in the repair of resin film material, a new film material piece for repair is prepared so as to cover the damaged part of the resin film material, and the resin film material to be repaired is covered with the damaged part. However, it is performed by joining the resin film material to be repaired by fusion, bonding with an adhesive, or the like.

The resin film material can be repaired by the method described above.
However, in the above-described repair of the resin film material, the resin film material to be repaired after the repair has an effect on the appearance because only the portion where the repair film material piece is fused increases in thickness. This is particularly noticeable at the edge of the film piece for repair.

  It is an object of the present invention to provide a method for repairing a resin film material with little deterioration in appearance even after repair.

In order to solve the above-mentioned problems, the present inventor proposes the following invention.
The present invention is a method of repairing a resin film material that repairs scratches made on a resin film material formed by covering both surfaces of a base fabric formed by weaving yarn with a resin resin layer. And the repair method of this resin film material is the process of excising the excision range which is the predetermined range containing the said crack among the said resin film material from the said resin film material, and the predetermined range around the said excision range The process of exposing the base fabric in the target range by removing the resin layer in the target range on both sides of the resin film material, the base fabric formed by weaving yarn, and the resin resin layer covering both sides A central portion having a size and shape corresponding to the cutting range, and surrounding the central portion formed by loosening a base fabric extending outward from the base fabric in the central portion. A process of preparing a repairing film material piece having a peripheral edge, and a process of arranging the repairing film material piece with respect to the resin film material so as to match the central part with the excision range; A thread included in the peripheral portion of the repair film piece; The inner edge of the excision range of the resin film material and the outer edge of the center portion of the repair film material piece are connected by performing peeling using the base fabric included in the target range of the resin film material Process.
In this repair method, when repairing a resin film material to be repaired, a resection range that is a predetermined range including a wound is excised. On the other hand, in this repair method, a repair film piece is used to fill the excision range. The repair film piece has a central portion mainly responsible for the function of filling the excision range. Although the film material for repair is not limited to this, it is generally made from a resin film material to be repaired. It is coated with. The central portion is also configured such that its size and shape correspond to the excision range. The central part is later fitted into the excision range of the resin film material. The size, shape, and the center part of the repair film piece, whose material is the same as the resin film material, are fitted into the cut area of the resin film material, and its peripheral edge is connected to the edge of the cut area of the resin film material. Is done. The repairing film material piece has a base fabric and a resin layer covering both sides thereof, and has the same basic configuration as the resin film material to be repaired, and thus has been repaired by this repairing method. The appearance of the later resin film material is unlikely to deteriorate, and it is easy to prevent the thickness where the repair film material piece is present from becoming thicker than other parts. Such an effect can be obtained remarkably when, for example, the thickness of the repairing film material piece and the resin film material are the same, and more prominently obtained when the repairing film material piece and the resin film material have the same configuration. .
In such a repair method, as described above, the peripheral edge, which is the edge of the central part of the repair film piece, and the edge of the excision range of the resin film material must be connected. In the present invention, this is realized as follows.
First, on the resin film material side, the base cloth existing in the target range is exposed by removing the resin in the target range, which is a certain range around the excision range. In addition, the removal of the resin layer is performed within the necessary range in order to be able to be peeled off from the repairing film material piece by exposing the base fabric, and the necessary range is the target range. . On the other hand, on the one side of the repair film material, a peripheral portion surrounding the center portion formed by loosening the base fabric extending from the base fabric in the center portion to the yarn is provided. In this method of repairing the resin film material, for example, the thread made from the peripheral edge of the repair film material piece is passed between the exposed yarns of the base fabric in the target range of the resin film material. By doing so, the resin film material and the repair film material piece are connected. As a result of such stripping, the target area of the resin film material and the peripheral edge of the repair film piece are the same as the base fabric in the resin film material or in the center of the repair film piece. It becomes a base fabric, and also becomes a series with the base fabric in the resin film material on the outside and the base fabric at the center of the repair film material piece on the inside. Therefore, the thickness of the repairing film material piece does not become larger than the other parts even in the part where the peeling is performed.
As described above, in the repair method of the resin film material of the present invention, the center portion of the repair film material piece, the peripheral edge portion of the repair film material piece, and the portion where the target range of the resin film material is separated are also resin. The thickness does not become larger than other portions of the film material. Therefore, the resin film material repaired by such a repair method is less likely to deteriorate in appearance due to the thickness being larger than that of other portions.

As described above, in the repair method of the resin film material of the present application, the stripping is performed using the bare base cloth existing in the target range of the resin film material and the yarn made from the peripheral edge of the repair film material piece. By doing so, the resin film material and the repair film material piece are connected.
This repair method may further include a process of covering both surfaces of the part where the peeling has been performed with a new resin layer which is a layer made of resin. The base fabric made by carrying out the stripping is bare in the state where the stripping has been performed. By covering the portion corresponding to the base fabric with the resin layer and the resin layer made of the resin that constitutes the resin layer of the resin film material, the portion that has been peeled off is the de facto base fabric made by the hooking. And a new resin layer corresponding to the resin layer of the resin film material covering both sides thereof, and it has almost the same configuration as the resin film material to be repaired, so the resin film material repaired by this repair method The appearance of is further improved. The new resin layer may partially cover the resin layer at the center or the resin layer of the resin film material. The resin that constitutes the resin layer of the resin film material is the same color as the resin that covers the outermost surface of the resin that covers the resin film material, or at least a color that appears to be the same visually. It can be selected, and then the appearance of the resin film material after repair can be improved. The resin constituting the new resin layer may be the same as the resin constituting the resin layer of the resin film material, and how to select the resin constituting the resin layer of the repair film piece (described later) ).
Any method may be used for covering the part that has been peeled off with the new resin layer. For example, by applying a resin dispersion to the part that has been peeled off and solidifying it. The part that has been peeled off can be covered with the new resin layer.
It is also possible to cover the part where the stripping has been carried out with a new resin layer by laminating resin sheet pieces and pasting them together by heat fusion or adhesion.
In performing the repair method of the resin film material, in the case where a new resin layer is formed on the part where the peeling has been performed, the resin constituting the resin layer of the resin film material (more specifically, the resin film material A film piece formed of a resin that can be fused or adhered to a layer present on the outermost surface of the resin layer may be attached to the resin film material so as to cover the new resin layer. This makes it possible to smooth the surface of the repaired part of the resin film material. In consideration of difficulty of conspicuousness, the film piece used in this case is preferably thin. For example, the thickness is preferably 0.5 mm or less, and more preferably 0.2 mm or less. Further, the resin that can be fused or adhered to the resin constituting the resin layer of the resin film material that forms the film piece may naturally be the same as the resin that constitutes the resin layer of the resin film material. By doing so, the film piece becomes less noticeable.

As described above, the repair method of the resin film material of the present application includes a process of removing the resin layer in the target range on both surfaces of the resin film material in order to expose the base fabric.
This process may be realized in any way. For example, a part of the peeling film material, which is a film material made of a resin whose surface can be fused with the resin constituting the resin layer, is used. Corresponds to the target range, and the remaining portion is positioned outside the target range, and then the part is fused to the target range, and the target range and the peeling film material are fused. Then, the peeling film material is peeled from the resin film material using the remaining portion of the peeling film material as a handle, so that the part of the peeling film material is integrated with the part. You may carry out by peeling the said resin layer. Thereby, the resin layer can be peeled relatively easily.
In the method of repairing a resin film material according to the present invention, the above-described process of removing the resin layer in the target range on both sides of the resin film material is a resin whose at least the surface is fusion-bondable with the resin constituting the resin layer. The peeling film material, which is the resulting film material, is arranged so that a part thereof corresponds to the target range and the remaining part is located outside the target range, and then the part is fused to the target range. After the target area and the peeling film material are fused, the peeling film material is peeled off from the resin film material using the remaining portion of the peeling film material as a handle. The resin layer in the entire target range may be peeled by repeating the process of peeling the resin layer in the target range integrated with the part of the film material a plurality of times. That is, the resin layer in the target range need not be peeled off by a single film material, and may be divided into a plurality of times using a plurality of film materials.

  In the repair method according to the present invention, as described above, the excision range which is a predetermined range including the range having a scratch on the resin film material is excised from the resin film material. The shape and size of the excision range is not particularly limited as long as it includes a scratch on the resin film material. For example, the excision range is preferably a rectangle along the yarn direction of the base fabric. By doing so, it becomes possible to facilitate the work of cutting.

The resin constituting the resin layer of the repair film piece can be selected as follows.
When the resin constituting the resin layer of the resin film material is one kind, the resin constituting the resin layer of the repair film piece is a resin constituting the resin layer of the resin film material. Can be the same. According to this, since the resin constituting the resin film material is the same as the resin at the center of the resin film material after repair, the appearance of the resin film material after repair is improved.
When the resin layer of the resin film material is a plurality of layers made of different resins, the resin layer of the repair film piece is made of the resin constituting the resin layer of the resin film material. Of these, the resin can be the same as the resin having the largest weight ratio. According to this, since most of the resins constituting the resin film material are the same as the resin at the center of the resin film material after repair, the appearance of the resin film material after repair is improved.
When the resin layer of the resin film material is a plurality of layers made of different resins, the resin layer of the repair film piece is a plurality of layers constituting the resin layer of the resin film material. It may be the same as the resin constituting the outermost layer. According to this, since the resin in the outermost layer of the resin constituting the resin film material is the same as the resin in the center of the resin film material after the repair, the appearance of the resin film material after the repair is improved. .
When the resin layer of the resin film material is made of a fluororesin, the resin layer of the repair film material piece may be made of a fluororesin. When the resin layer of the resin film material is made of a fluororesin, the resin layer of the repair film material piece should basically be composed of the same resin as that constituting the resin layer of the resin film material. . Although it is the most common type of fluororesin, its visual appearance is not much different at the visual level even if the type is different. Therefore, when the resin layer of the resin film material is made of a fluororesin, if the resin layer of the repair film piece is made of a fluororesin, the appearance of the resin film material after repair is inevitable. Get better.
Similarly, the base fabric of the resin film material and the base fabric of the repair film piece can be the same. Thereby, the appearance of the resin film material after repair is improved. Also, if the base fabric of the resin film material and the base fabric of the repair film piece are the same, it is easy to perform the above-described peeling, and the strength of the portion where the peeling has been performed after the repair is the same as that of the original resin film material. It can also be assumed that the strength is not inferior.

  Hereinafter, a preferred embodiment of the present invention will be described with reference to the drawings.

First, the configuration of the resin film material to be repaired in this embodiment will be described with reference to the cross-sectional view of FIG.
The resin film material 100 may be a known material, but includes a base cloth 110 and a resin layer 120 that covers both surfaces thereof.
The base fabric 110 has a large number of warp yarns 111 and weft yarns 112, both of which are yarns, and these are woven.
The warp yarn 111 and the weft yarn 112 are made of synthetic fibers such as polyester, natural fibers such as kenaf fibers, and inorganic fibers such as glass fibers. The material of the warp yarn 111 and the weft yarn 112 need not be the same. However, the warp yarn 111 and the weft yarn 112 in the resin film material 100 of this embodiment are the same material, and both are glass fibers.
The resin layer 120 is made of resin. The thickness of the resin layer 120 is set to a thickness that can ensure the flexibility of the resin film material 100. In this embodiment, the thickness of the resin layer 120 is not necessarily limited to this, but the thickness is adjusted so as to ensure functions such as translucency required for the resin film material 100.
The resin layer 120 is made of, for example, a synthetic resin such as polyvinyl chloride resin, silicon resin, or fluorine resin. In this embodiment, the resin layer 120 is not limited to this, but is a multilayer made of a fluororesin of PTFE (tetrafluoroethylene resin) and FEP (tetrafluoroethylene / hexafluoropropylene copolymer). is made of. More specifically, the layer made of PTFE is in contact with the base fabric 110, and the layer made of FEP covers the layer made of PTFE. The layer made of PTFE ensures the flame retardancy of the resin film material 100 and has a certain thickness, but the FEP layer is a resin film in view of the melting point of PTFE being higher than the melting point of FEP. In order to facilitate thermal fusion between the materials 100, the material 100 is provided on a layer made of PTFE. Therefore, the FEP layer is much thinner than the PTFE layer, and PTFE, which is a resin constituting the layer made of PTFE, is considered much farther than FEP, which is the resin constituting the layer made of FEP, in terms of weight ratio. Of course, the resin layer 120 may be a single layer. Further, the resin layer 120 may be three layers above.

Next, a method for repairing the resin film material 100 described above will be described. Although not restricted to this, the resin film material 100 shall already be used, for example as a roofing material.
FIG. 2 is a plan view showing a part of the resin film material 100, and it is assumed that the resin film material 100 has scratches X. The scratch X may or may not penetrate through the resin film material 100, but the resin film material 100 needs to be repaired.

When repairing the resin film material 100, a resection range 100A that is a predetermined range including the entire wound X in the resin film material 100 is determined (FIG. 3). The cut range 100A is not necessarily limited to this, but is rectangular in this embodiment.
The excision range 100A may be a minimum range including the wound X, and in this embodiment, a minimum rectangle including the wound X is sufficient. However, the ease of performing the stripping operation described later is considered. If so, it is preferable to have a certain size (for example, the length of one side of the rectangle is 3 cm or more). On the other hand, if the excision range 100A is made too large, the area that must be subjected to the work of stripping increases and the work burden becomes excessive. Therefore, the size of the excision range 100A substantially includes the wound X and the work of the scissors that occurs later. It is preferable to set the minimum size among the sizes that are easy to perform.
The cut range 100A is not necessarily limited to this, but the two opposite sides thereof are parallel to the warp yarn 111 of the base fabric 110, and the other two opposite sides thereof are parallel to the weft yarn 112 of the base fabric 110. Preferably, this is the case in this embodiment.

  When the excision range 100A is determined, the excision range 100A is excised from the resin film material 100 (FIG. 4). The excision of the resin film material 100 may be performed by a known method using an appropriate tool such as a cutter.

Next, the target range 100B is determined around the excision range 100A (FIG. 4). The target range 100B effectively surrounds the excision range 100A with a predetermined width. The widths in the respective parts of the target range 100B need not all be the same.
The target range 100 </ b> B is a portion where a work of patching described later is performed. The width of the target range 100 </ b> B is set such that the connection between the resin film material 100 and the repairing film material piece described later is sufficiently strong after the stripping. As will be described later, the base fabric 110 in the target range 100B is used for hooking, but if the width of the target range 100B is too narrow, the resin film material 100 and the repairing film material piece after the hooking are performed. Since the connection does not become sufficiently strong, the width of the target range 100B needs to be increased to some extent. On the other hand, if the width of the target range 100B is too large, the range in which the stripping work must be performed becomes wide, and the work burden becomes excessive. In consideration of the above, in principle, the width of the target range 100B should be minimized within a range where the connection between the base fabric 110 of the resin film material 100 and the repair film piece is sufficiently strong.

Next, the resin layer 120 existing in the target range 100B is removed (FIGS. 5 to 8).
The removal of the resin layer 120 is not limited to this, but in this embodiment, the following method is used.
In this embodiment, a peeling film material 200 which is a film material having at least a surface made of a resin that can be fused with the resin layer 120 of the resin film material 100 is used as the resin layer in the target range 100B of the resin film material 100. The resin layer 120 fused to the peeling film material 200 is also peeled off from the base cloth 110 of the resin film material 100 by fusing the film 120 and peeling the peeling film material 200 from the resin film material 100. I try to let them.
The peeling film material 200 may be formed of a plurality of layers like the resin film material 100, or may be formed of a single layer of only a resin that can be fused to the resin layer 120. The peeling film material 200 of this embodiment employs the latter configuration. Examples of the resin that can be fused to the resin layer 120 in the peeling film material 200 include the same resin that constitutes the resin layer 120. In addition, for example, when the outermost layer of the resin layer 120 is FEP, examples of the resin that can be fused to the resin layer 120 include a fluororesin such as PTFE. In the case of a vinyl chloride resin, an example of a resin that can be fused to the resin layer 120 is a polyurethane resin.
The peeling film material 200 includes a fused portion 201 that is a portion fused to the target range 100B and a non-fused portion 202 that is a portion not fused to the target range 100B.
The shape and size of the fused portion 201 may be the same as the shape and size of the entire target range 100B, but in this embodiment, the shape and size of the fused portion 201 correspond to a part of the target range 100B. It is supposed to be. More specifically, as shown in FIG. 5, the fused portion 201 in this embodiment has a rectangular shape corresponding to one side of the square-shaped target range 100 </ b> B (more precisely, longer than one side) It has become. Of the peeling film material 200, a portion overlapping the target range 100 </ b> B is a fused portion 201. On the other hand, a portion that does not overlap with the target range 100 </ b> B is a non-fused portion 202. The fused portion 201 is fused to the target range 100B by a known method such as heat fusion, and the non-fused portion 202 is not fused to the target range 100B (FIG. 6).
When the fused portion 201 of the peeling film material 200 is fused to the target range 100B, the operator grips the non-fused portion 202 as a handle and pulls it to remove the peeling film material 200 from the resin film material 100. Peel off. By doing so, a part of the resin layer 120 in the target range 100 </ b> B fused to the fusion part 201 of the separation film material 200 is forcibly separated from the base fabric 110 together with the separation film material 200. become. As shown in FIG. 7, the base fabric 110 is viewed from a portion of the resin film material 100 where the peeling film material 200 is peeled off.
The above processing is performed on the other three sides of the square-shaped target range 100B, and all the resin layers 120 existing in the target range 100B are removed (FIG. 8). Note that there is no problem even if some of the resin layer 120 remains in the target range 100B.
In addition, the shape and size of the fused portion 201 of the peeling film material 200 are the same B shape as the shape and size of the entire target range 100B, and a non-fused portion that can be used as a handle somewhere. When 202 is provided, the resin layer 120 existing in the entire target range 100B can be peeled off by peeling the peeling film material 200 from the resin film material 100 once.
Subsequently, the above process is performed also on the other surface of the resin film material 100, and all the resin layers 120 existing in the target range 100B on the other surface are removed. The target range 100B of the one surface and the other surface of the resin film material 100 is basically the same shape and size.

Note that the order of the steps so far can be changed.
For example, the excision of the excision range 100A from the resin film material 100 may be performed after the resin layer 120 existing in the target range 100B is removed from the target range 100B even after the target range 100B is determined. The determination of the target range 100B may be performed before the determination of the excision range 100A.
Furthermore, it is not necessary to intentionally determine the target range 100B. As described above, the target range 100B exists around the ablation range 100A. Even if the target range 100B is not particularly conscious, if the peeling film material 200 formed in an appropriate width is fused around the cutting range 100A and then peeled off from the resin film material 100, the result is as a result. The peeled portion of the resin layer 120 is the target range 100B.

Next, a repairing film material piece 300 connected to the resin film material 100 is prepared (FIG. 9).
The repair film piece 300 includes a central portion 301 and a peripheral portion 302 surrounding the periphery.
The central part 301 is composed of at least three layers, like the resin film material 100. Although not shown, the center portion 301 includes a base fabric that is a fabric at the center and a resin layer made of resin provided on both surfaces of the base fabric.
The yarn constituting the base fabric in the central portion 301 may or may not be the same as the yarn constituting the base fabric 110 of the resin film material 100, but in this embodiment, both are the same. . Further, the yarn constituting the base fabric in the central portion 301 is woven in the same weaving manner as the yarn constituting the base fabric 110 of the resin film material 100. As a result, the base fabric in the central portion 301 and the base fabric 110 of the resin film material 100 are the same.
The resin constituting the resin layer of the repair film piece can be selected as follows.
The resin constituting the resin layer of the repair film piece can be selected as follows.
When the resin constituting the resin layer 120 of the resin film material 100 is one kind, the resin constituting the resin layer of the repair film piece is the same as the resin constituting the resin layer 120 of the resin film material 100. can do. For example, if the resin layer 120 of the resin film material 100 is made of polyvinyl chloride, the resin layer of the central portion 301 can be made of polyvinyl chloride.
When the resin layer 120 of the resin film material 100 is a plurality of layers made of different resins, the resin layer of the repair film material piece is the weight of the resin constituting the resin layer 120 of the resin film material 100. The ratio can be the same as the most resin. As described above, in this embodiment, the resin having the largest weight ratio among the resin layers 120 of the resin film material 100 is PTFE. Therefore, according to this, the resin layer of the central portion 301 can be PTFE. .
When the resin layer 120 of the resin film material 100 is a plurality of layers made of different resins, the resin layer of the repair film material piece is the outermost layer of the plurality of layers constituting the resin layer 120 of the resin film material 100. It can be made the same as the resin constituting. As described above, in this embodiment, since the outermost layer of the resin layer 120 of the resin film material 100 is made of FEP, the resin layer of the central portion 301 can be made of FEP.
When the resin layer 120 of the resin film material 100 is made of a fluororesin, the resin layer of the repair film material piece may be made of a fluororesin. As described above, in this embodiment, the resin layer 120 of the resin film material 100 includes a layer made of PTFE and a layer made of FEP, and both PTFE and FEP are fluororesins. Therefore, the resin layer of the central portion 301 can be made of PTFE, FEP, or other fluororesin.
In addition, the resin layer of the central portion 301 may meet the same as the resin layer 120 of the resin film material 100. In this case, the repairing film material piece 300 can be made of the same kind of film material as the resin film material 100.
The peripheral portion 302 includes a large number of yarns that are loosened and loosened from the base fabric in the center portion 301 to the outside. Although not restricted to this, the warp and the weft contained in the base fabric of the center part 301 in this embodiment are orthogonal to any two sides of the rectangular center part 301 and are parallel to the other two sides. The work of loosening the base fabric of the repair film piece 300 is performed by leaving a thread (one of the warp and the weft) that is perpendicular to each side from each side of the center portion 301 and a thread parallel to each side (the warp and the warp). This is done by removing the other of the weft.
As a result, the yarn included in the peripheral edge portion 302 is orthogonal to each side of the central portion 301 and continues from the base fabric in the central portion 301.

Next, the center portion 301 of the repair film piece 300 is positioned so that the latter overlaps the former in the excision range 100A of the resin film material 100, and the base fabric 110 of the target range 100B along each side of the excision range 100A. Then, using the thread extending from each side of the central portion 301 of the repair film piece 300 adjacent to each side of the cutting range 100A, the filing process is performed (FIG. 10).
Such hooks pass through the yarn extending from each side of the central portion 301 of the repair film piece 300 adjacent to each side of the cutting range 100A between the yarns of the base fabric 11 of the target range 100B along each side of the cutting range 100A. Go and finally cut the waste yarn. As a method of lacquering, this is an ordinary one, which is often used, for example, as a lacquering of cloth constituting clothing.
Thereby, the repair of the resin film material 100 is completed.

Although the repair of the resin film material 100 has been temporarily completed by the above-described process, as an additional process, the resin dispersion is applied to both sides of the part where the peeling has been performed, and is cured, and then the peeling is performed. The coated portion can be covered with a new resin layer 130 that is a layer of the solidified dispersion (FIG. 11).
The resin contained in such a dispersion can be selected by the same method as the resin covering the center portion 301. However, the resin covering the center portion 301 and the resin contained in the dispersion are not necessarily the same.
The new resin layer 130 is made of resin (preferably selected as described above, preferably the same resin as that constituting the resin layer 120 of the resin film material 100), and the outermost layer of the central portion 301 is also a resin. (The resin selected as described above, preferably the same resin as the resin constituting the resin layer 120 of the resin film material 100). Therefore, from the outside, the resin layer 120 of the resin film material 100 and the new resin layer 130 are formed. The series of surfaces following the central portion 301 of the repair film piece 300 can be seen as a series of surfaces that have not been repaired. The new resin layer 130 is a sheet piece made of the same resin as that contained in the above-described dispersion and having a shape and size corresponding to the range in which the above-described dispersion is applied. It is also possible to form it by adhering to a range corresponding to the range to which the dispersion is applied by adhesion or fusion.
Note that the new resin layer 130 may also cover the resin layer 120 of the resin film material 100 or the central portion 301 of the repair film material piece 300 on both sides of the resin layer 130 as long as it covers the portion where the stripping has been performed. Absent.
Further, as a further additional process, the additional film 400 that covers at least the new resin layer 130 and the center portion 301 of the repair film piece 300 is replaced with the resin film material 100 (more precisely, the center portion 301 and the new resin For example, it may be attached to the layer 130 by fusion (FIG. 12). The additional film 400 is, for example, a single-layer resin film made of the same resin as that constituting the resin layer 120 of the resin film material 100. The resin constituting the additional film 400 can be selected, for example, by the same method as the resin that covers the center portion 301.
By performing such treatment, an effect that the surface can be smoothed can be obtained. In this case, since the outermost layer of the resin layer 120 of the resin film material 100 is FEP, the same resin as the outermost layer, that is, FEP should be selected as the resin constituting the additional film 400. Further, the additional film 400 is preferably thin from the viewpoint of appearance. The thickness is 0.5 mm or less, preferably 0.2 mm or less.
