Problems solved by technology

Its disadvantages are: the waterproof performance of the packaging film is poor, it is not suitable for packaging medicines that are sensitive to light, water vapor and oxygen, and the scope of application is narrow
Expensive drugs and new drugs with excellent therapeutic effects produced by Chinese pharmaceutical companies, due to the strict requirements of the drug itself on packaging and the need to enter the international market, the packaging of solid drugs are all imported, resulting in too high a cost

Embodiment Construction

[0018] The barrier property of aluminum foil is very good, not light, moisture, and air. However, due to the purity of aluminum and the rolling environment, the quality of aluminum foil will be affected. When the aluminum foil is rolled below 0.015mm, pinholes tend to appear. The more pinholes, the larger the pore size, the greater the permeability and the worse the barrier property. Since the thickness of the aluminum foil is thinner, the packaging performance is worse, but the calendering cost of the aluminum foil is high. Combined with the purpose of the present invention, it is to provide a kind of high-grade medicine. Packaging material, so the thickness of aluminum foil is 0.055mm.

[0019] The concrete processing process of the product of the present invention is as follows:

[0020] 1. The polyurethane glue and the polyurethane glue ester are strictly formulated into a polyurethane adhesive according to the weight ratio of 100:20, and stir evenly. The diluent is the ...

Abstract

The invention relates to a composite rigid sheet used to pack solid medicine and relative preparation, wherein it uses aluminum layer as central layer whose one surface via polyurethane adhesive layer is adhered to the polyamide layer and another surface via polyurethane adhesive layer is adhered to the polychloroethylene layer; the thickness of aluminum is 0.055mm; the thickness of polyamide layer is 0.025mm; the thickness of polychloroethylene layer is 0.055mm. The invention uses dry compose machine, and solidification. And the product has better thermal insulation and gas insulation, to keep medicine longer.

Description

technical field [0001] The invention relates to a packaging material and a preparation method thereof, in particular to a composite hard sheet used for solid medicine packaging and a preparation method thereof. Background technique [0002] With the rapid development of my country's pharmaceutical industry, the pharmaceutical packaging industry has gained a huge living space. There is a big gap between the packaging quality of most domestic pharmaceutical products and developed countries. Keeping up with the pace of international counterparts, seizing opportunities, and establishing a packaging concept that meets the needs of the times have become the top priority of the local pharmaceutical packaging industry. The traditional concept of packaging believes that the purpose of packaging is only to contain and protect products for transportation. The background of the emergence of this concept and its existence is the era of seller's market where the product level is low and...
