Description

  The present invention relates to a packaging material used for packaging of products stored in a container, and more particularly to a product packaging material with a header having a header capable of storing and displaying the packaged products by hanging them on a hook.

Conventionally, it is known to wrap a product in a packaging bag with a header, and the method is known in the gazettes of Japanese Utility Model Publication Nos. 55-233962 and 59-33786. the packaging bag for packaging, the utility model registration No. 2521171 discloses discloses.
Japanese Utility Model Publication No. 55-23962 Japanese Utility Model Publication No.59-33786 Utility Model Registration No. 2521171

These conventional packaging bags with a header are difficult to package tightly when packaging a box-shaped container, and it is necessary to design the packaging bag in accordance with the shape and size of the product, so that the versatility is poor. Utility Model Header with product packaging bag disclosed in Registration No. 2521171 publication solves the problem of packaging tight by providing the gusset portion to the header lower edge, but should be designed in accordance with the geometry of the product And there is a problem in cost.

  As a result of researching a packaging material with a header that can always be tightly packed in response to changes in the shape and dimensions of the box-shaped container, the present invention is to fold the lower edge of the packaging material along the box-shaped container and attach it with an adhesive layer Thus, the above problem is solved.

That is, the present invention
(1) A header part 3 is formed on the upper edge of the packaging body film 1 made of two synthetic resin films, separated from each other by a heat welding seal part 6 by heat welding, and extends downward from the header part 3. The front and back surfaces of the packaging material main film 1 are connected by a heat-welded portion 4 in which the lower edges of the front and back films of the packaging material main film 1 are heat-welded, and an adhesive surface 8 is provided on the lower edge portion. Product packaging material with a header, which is formed by opening the cut surface 2 on the side surfaces of the front and rear surfaces of the film,
(2) The product packaging material with a header according to item 1, wherein an adhesive layer is provided on one of the front and rear surfaces of the packaging material, and a release paper is attached.
(3) The product packaging material with a header according to item 1, wherein a core material sheet is sandwiched in the laminated structure of the header portion,
(4) The product packaging material with a header according to any one of Items 1 to 3, wherein the product is a box-shaped container,
Is to provide.

The present invention is such goods with a volume as a box-shaped container, the actual Sho 55-23962 discloses a conventional technology in the header with suspended bag, etc., Japanese Utility Model 59-33786, JP-Utility Model Registration No. 2521171 Although a gazette is disclosed, the cost is high and packaging cannot be performed tightly. The following effects can be achieved that can be easily and tightly packaged at low cost.
(1) The cost of the packaging material with the header can be reduced.
(2) packaging work process, fixed with an adhesive 9 a box shape container header with packaging material, bending the bending portion 13 along the longitudinal film lower edge 4 to the box-shaped container, with the adhesive 8 Just stick. Easy to take out after storage.
A product having a large volume is not limited to a box-shaped container.

The synthetic resin film used for the packaging material with a header of the present invention can be used without particular limitation as long as it is a thermoplastic synthetic resin film. For example, polypropylene resin, polyethylene resin, ethylene vinyl acetate copolymer, styrene-butylene copolymer can be used. Resin films such as polymers, acrylic resins, nylon, and PET, and laminate films of these resin films can be suitably used.
The product packaging material with a header of the present invention is a packaging material produced by a known continuous bag making method. For example, a long strip-shaped resin film is continuously half-fold polymerized to form a strip-shaped half-fold polymerized laminated film. An adhesive layer and a release layer are provided at any location on the inner surface, and the lower edge portion of the belt-like laminated film is fused or welded, and the adhesive tape portion is attached to the lower edge portion to provide a release paper. The laminated film is cut and separated at the portion corresponding to the side edge of the product packaging material with header to form the product packaging material with header.

The present invention is to melt-weld or weld the lower edge portion of the packaging material with a header, and fold and stick the box-shaped container along the box-shaped container in response to changes in the shape and dimensions thereof. The length of the packaging material with a header is always longer than the length of the box-shaped container, and the packaging material with a header can be always folded. Furthermore, in order to fix the product packaging material with a header and the box-shaped container so as not to be separated, there is a feature that an adhesive layer is provided at an arbitrary position on either the front or back of the product packaging material film with a header.
This feature will be described with reference to the drawings of the following examples, but the present invention is not limited thereto.

FIG. 1 is a cross-sectional view of a packaging material with a header according to an embodiment of one aspect of the present invention. The synthetic resin film is subjected to half-fold polymerization, and the lower edge portion 4 subjected to the half-fold polymerization is fused or welded, and the adhesive tape portion 7 is attached to the lower edge of the packaging material with a header. A double-sided tape 9 and a release paper 12 are provided on either of the front and rear films of the product packaging material with a header, which is extended from the welding seal portion 6 on which the header core sheet 11 is welded while the synthetic resin film is polymerized in half. It is sectional drawing of the state suspended by the down hole 5. FIG.
FIG. 2 is a plan view of the packaging material with a header.
FIG. 3 is a side view of a box- shaped container packaged with a header packaging material.
FIG. 4 is a perspective view of a box- shaped container wrapped with a header wrapping material.

  As the release paper used for the adhesive layers 7 and 9 of the present invention, a thin film made of a synthetic resin having a known release function such as a silicon release material can be suitably used.

FIG. 1 is a developed sectional view of an embodiment of the present invention. FIG. 2 is a plan view of the present invention. FIG. 3 is a side view of a box-shaped container packaged. FIG. 4 is a perspective view in which a box-shaped container is packaged.
