Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a Nipristar packaging, and more particularly relates to a tamper-proof Nipristar packaging.

[Conventional technology]

Conventionally, individual thin-walled plastics were pre-thermoformed, and the molded parts were individually measured.

This is then covered with a card-like mount coated with wax on one side and heat-sealed to form a pre-printed paper, which is used for toy packaging, industrial material packaging, food packaging, drug packaging, etc.

This conventional sealant is opened by peeling off the wax layer between the eyebrows, and there is a possibility that it can be resealed after being opened, and there is no means to detect or prevent tampering. It's something that doesn't exist.

[Problem that the invention seeks to solve]

Therefore, the problem to be solved by the present invention is to provide a pristar package provided with means for detecting or preventing tampering.

[Means for solving problems]

As a result of research in order to solve the above problems, the present inventor found that the release columnar surface of a base paper having a release property on one side, or a base paper with a release layer laminated on one side to impart release properties. A transparent resin ink layer is provided on the entire surface, a polyolefin resin layer is provided on the transparent resin ink layer, and a hot melt adhesive layer is further provided on the polyolefin resin layer. A mount and a film molded body are placed in the molded recess of the film molded body. We have discovered that it is possible to form a tamper-proof pristar package by heat-sealing between the surface of a single mount and the surface area of the film molded object facing it while the contents are accommodated, and based on this knowledge, Thus, the present invention was completed.

°The Pristar packaging of the present invention is made of a base paper that has release properties on one side, or a base paper that has a release layer laminated on one side to provide release properties, and a transparent resin ink layer on both surfaces. , a polyolefin resin layer is provided on the transparent resin ink layer, and a hot melt adhesive layer is further provided on the polyolefin resin layer, and a mount and a film molded body are placed in a state in which the contents are accommodated in the molded recesses of the film molded body. The mount surface and the opposing surface area of the film molded body are heat-sealed.

Therefore, in the present invention, it is used as a base paper.

Aluminum foil, plastic film, or plastic film is applied to the first layer, which is a vapor-deposited film formed by vapor-depositing one side of paper, aluminum foil, plastic film, or plastic film, through an interlayer adhesive layer such as adhesive or polyethylene. A composite sheet formed by laminating a second layer made of a vapor-deposited film coated with VcyX on one side of a film may be used.

The plastic and film that make up the base paper are polyester, polyamide, polypropylene, and saponified ethylene-vinyl acetate copolymers.

Alternatively, a polyvinylidene chloride coated film, so-called a coated film, can be applied to these films.

When the second layer is made of biphasically oriented polypropylene, polynisdel, biaxially oriented polyamide, or a film thereof coated with vinylidene chloride, it is not necessary to provide a release layer.

Of course, characters, patterns, etc. may be printed on the side surface of the first layer or the side surface of the second layer of the base paper using a conventional printing method.

0.1 to 5 as a release layer to polyamide, nitrocellulose, polyamide-nitrocellulose, rubber, urethane, or chlorinated polypropylene resin.
A material prepared to be easily peeled and bonded to a polyolefin resin layer with a strength of 10 to 200F/30m width by adding a mold release agent such as lincon or a surfactant dissolved in a solvent within the range of A coating can be applied. In addition, when the second layer of the base paper is made of aluminum foil, a vinyl chloride resin-based, vinyl chloride-vinyl acetate copolymer-based, or acrylic resin-based anchor coat layer is provided, then a release layer is provided, and the separation between the base paper and the base paper is improved. Make sure that sufficient adhesive strength is obtained.

Next, chlorinated polypropylene is used as a transparent resin ink layer. Also, chlorinated ethylene vinyl alcohol.

or polyester-based or ethylene acrylic acid copolymer resin-based emulsion, ionomer emulsion,
Alternatively, an ink composition made of wax may be printed by a printing method such as a gravure printing method, or applied by a method such as a gravure coating method.

Next, as a polyolefin resin layer, a polyolefin resin such as polyethylene or polypropylene may be extrusion coated, or a polyolefin resin film such as polyethylene or polypropylene may be dry laminated. The appropriate thickness of this layer is 15 to 50 microns.

Next, as a hot melt adhesive layer, a mixture of paraffin wax or microwax, polyethylene or ethylene vinyl alcohol, or modified products thereof, an i-additive, etc., and other additives as necessary is applied. I can do it. As the material for the hot-melt adhesive layer, a material is selected that can provide a drawstring strength of 600 y/15 m or more in width with the surface of the film molded object to be sealed. 600P/
This is because if the width is less than 15 m, peeling may occur easily, and there is a risk that the mount may peel off from the film molding during storage or transportation.

Next, in the present invention, polyvinyl chloride, high impact polystyrene, polypropylene, polyethylene, or a laminated film thereof can be used as the material for the film molded body.

[For production]

In the present invention, the release surface of the base paper allows the polyolefin resin layer to be peeled off.

Therefore, when an attempt is made to peel off the mount, separation occurs between the base paper and the polyolefin resin layer, and the polyolefin resin layer is separated from the base paper while being adhered to the film molding.

Next, when the base paper is peeled off, the transparent resin ink layer undergoes cohesive failure and most of it is removed to the side of the polyolefin resin layer, and as a result, the transparent resin ink layer turns white.
