Problems solved by technology

That is, there is a problem that when the package is discarded after taking out the contents, it is desired to separately collect the base material made of plastic and the cover material made of aluminum foil from the viewpoint of recycling resources recently, which requires a lot of effort. , it is physically difficult
In addition, in the case of incineration, there are also problems such as damage to the incinerator due to the high calorific value of the aluminum foil, and a decrease in incineration efficiency due to fusion and integration.
In addition, a huge amount of electric energy is required in the manufacture of aluminum, and in terms of cost and CO 2 Environmental aspects such as emissions are also problematic
Furthermore, at the PTP packaging site, the actual situation is that the loading and unloading of the aluminum foil lid material roll to the packaging machine is basically done manually, and the burden on the operator increases due to handling heavy objects, and there is a risk of injury due to falling.

Embodiment 1

[0116]As the styrene-based resin, SMAA-1, HIPS-1, and HIPS-2 were used, respectively mixed in the ratio shown in Example 1 of Table 1, and a biaxially stretched film was formed by blow molding. Next, after corona treatment of 50 mN / m was performed on the obtained film, the above-mentioned alphabetical characters were printed using a gravure printing machine, and OP varnish was applied thereon. Furthermore, on the surface opposite to the printed surface, after corona treatment of 50 mN / m was performed in the same manner, it was converted into a dry film at about 7 g / m 2 The thickness of the ethylene vinyl acetate emulsion type heat sealant is applied to form a PTP lid material film. Next, the substrate sheet is made of polyvinyl chloride (PVC) with a thickness of 200 μm, and a concave portion is formed by a PTP molding machine (FBP-M1 manufactured by CKD Co., Ltd.), the substrate is filled with tablets, and the above-mentioned PTP caps are joined. Material film, obtained PTP p...

Embodiment 2

[0118] As the styrene-based resin, except that SMAA-2 and HIPS-3 were used in the compounding ratio described in Example 2 of Table 1, a biaxially stretched film was produced in the same manner as in Example 1, and then a PTP film was produced in the same manner. The lid material film was obtained as a PTP package.

[0119]

[0120] The PTP packages in Example 1 and Example 2 are packages made using a cover material film that does not contain inorganic fillers. When heat sealing with the base material, no deformation such as wrinkles occurs on the cover material film, and stable heat can be performed. It is a package body that is airtight and excellent in packing suitability. In addition, both the press-penetration property and printing clarity of the produced PTP package were very good.

[0121] In addition, regarding the extrusion sound of the tablet, the crackling sound is loud and clear, which is very good. For tablet extrusion volume, embodiment 1 is 61.7dB, embodimen...

Embodiment 3

[0124] Containing silica as an inorganic filler, a biaxially stretched film (thickness: 15 μm) with an area stretch ratio increased by about 30% was produced, and this was used as a cover material, and a PTP package was produced in the same manner as in Example 1. body.

Abstract

The press-through package of the invention has a covering material composed of a stretched film including at least one layer, the layer comprising a thermoplastic resin including at least one selected from the group consisting of styrene-acrylic acid copolymer resins, styrene-methacrylic acid copolymer resins, styrene-maleic anhydride copolymer resins and terpolymer resins comprising one of these three copolymer resins and an ester component, and an inorganic filler at less than 5 parts by weight with respect to 100 parts by weight of the thermoplastic resin.

Description

technical field [0001] The present invention mainly relates to a blister package having a cover material film suitable for packaging medicines such as tablets and capsules, or foods such as candy and chocolate. Background technique [0002] As one of the packaging methods for medicines, foods, etc., a blister pack (hereinafter referred to as PTP) package including a base material and a cover material is known. The PTP packaging body is formed as follows: a plastic sheet made of polyvinyl chloride resin or polypropylene resin is formed into a base material having a pocket-shaped recess by vacuum forming or pressure forming, and after the content is filled in the recess, The flange portion other than the recessed portion is sealed with a heat-sealable cover material. [0003] The PTP package is configured in such a way that, with respect to the stored contents, a force is applied from the outside of the base material toward the cover material to break the cover material, ther...
