Embodiment 1

[0016] Blister medical blister film suitable for packaging, including an aluminum foil layer, one side of the aluminum foil layer is provided with a layer of protective film produced by coating a protective agent, and the other side of the aluminum foil layer is provided with a plastic sheet, the aluminum foil layer and plastic The sheets are heat-sealed through the adhesive layer;

[0017] The plastic sheet is prepared by calendering with resin, heat stabilizer and lubricant. The resin, heat stabilizer and lubricant are respectively used in the following parts by mass: 35-50 parts, 20-25 parts, 10-15 parts;

[0018] The protective agent includes the following components by mass: 25-30 parts of nitrocellulose, 17-25 parts of synthetic resin, 6-9 parts of plasticizer, 3-5 parts of cosolvent, and 10-15 parts of diluent;

[0019] Further, any one of acetamide, urea, and nicotinamide is used as the cosolvent.

[0020] Further, the adhesive layer is made of nitrocellulose fiber, a...

Embodiment 2

[0031] The preparation was carried out completely according to the method of Example 1, and the difference from Example 1 was that the following parts by mass were used for resin, heat stabilizer and lubricant: 40-48 parts, 23-24 parts, and 13-14 parts.

Embodiment 3

[0033] Completely prepared according to the method of Example 1, what is different from Example 1 and Example 2 is: the protective agent includes the following components by mass: 25-27 parts of nitrocellulose, 19-23 parts of synthetic resin, plasticizer, 7-8 parts, 3-4 parts of co-solvent, 12-14 parts of diluent.

Abstract

The invention relates to the technical field of medical plastic-suction films, in particular to a blister medical plastic-suction film suitable for packaging. One side of an aluminum foil layer is provided with a protective film produced by coating of a protective agent, the other side of the aluminum foil layer is provided with a plastic sheet, and the aluminum foil layer and the plastic sheet are heat-sealed through an adhesive layer. The design is novel, materials are exquisite, the protective film can play a certain role in toughness and abrasion protection on the aluminum foil layer, the problem of overall breakage caused by stress during die cutting is avoided, meanwhile, product information on the surface of the aluminum foil layer can be protected, and the situation that the drug use danger is increased due to product information disappearance caused by abrasion is avoided. The aluminum foil layer and the plastic sheet are seamlessly attached through the adhesive layer, the problem that layering and falling are prone to occurring is solved, the plastic sheet prepared from resin, a heat stabilizer and a lubricant has good heat stability, and the problems that in the heat sealing process of a product, molecular crosslinking is prone to occurring, and consequently the product becomes black and is poor in physical performance are solved.

Description

technical field [0001] The invention relates to the technical field of medical blister film, in particular to a blister medical blister film suitable for packaging. Background technique [0002] The blister packaging of medicines is filled with medicines in the blisters formed by vacuum foaming (blowing) or compression molding, and covered with aluminum foil, etc., and heat-sealed with the blister substrate under certain temperature and time conditions under pressure. made. However, the current blister film on the market is prone to delamination and rupture during die-cutting, and the product information on the surface of the aluminum foil layer is easily worn off. Therefore, those skilled in the art provide a blister medical blister film suitable for packaging to solve the problems raised in the above-mentioned background technology. Contents of the invention [0003] The object of the present invention is to provide a blister medical blister film suitable for packaging...
