Problems solved by technology
At present, medicinal blisters and polyvinyl chloride have existed in our country for many years. As a material for packaging drugs, it has good processing performance and light texture, but medicinal polyvinyl chloride has hidden dangers in safety.
First of all, it contains chlorine, and it will be polluted by chlorine to some extent in medicines with a long storage period, which will have a great impact on human body and health. Secondly, medicinal polyvinyl chloride is the permeability of water vapor and oxygen. The overdose is large, and the impact on the stability of the drug quality is fatal. It greatly shortens the storage and guarantee period of the drug. It generally adopts a dry compound process in production

Embodiment Construction
[0011] The present invention will now be further described in conjunction with the accompanying drawings and preferred embodiments. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.
[0012] like figure 1 A cold stamping pharmaceutical composite hard sheet shown has a polyamide layer 1, an aluminum layer 2 and a polyvinyl chloride layer 3, an aluminum layer 2 is attached to the polyvinyl chloride layer 3, and an aluminum layer 2 is attached to the aluminum layer 2. There is a layer of polyamide1. The polyamide layer 1, the aluminum layer 2 and the polyvinyl chloride layer 3 are bonded by an adhesive layer. Good cold stamping performance, waterproof, light-blocking, taste-retaining, light-shielding, and heat-resistant. When rolling below 0.015mm, pinholes often appear. The more pinholes, the greater the air permea...

Abstract
The invention relates to a package material, and especially relates to a cold punching press type medicinal composite hard sheet. The invention relates to a polyamide layer, an aluminum layer and a polyvinyl chloride layer, the polyvinyl chloride layer is attached with the aluminum layer, and the aluminum layer is attached with the polyamide layer. The cold punching press type medicinal composite hard sheet has the characteristics of good waterproof resistance, gas barrier property, flavor and odor barrier property, light shading performance, thermal resistance performance, and is suitable for the package materials with high sealing performance and long shelf life of expensive medicines and new medicines, the pollution of the medicines can be avoided, the electric energy can be saved, and the pollution on air can be avoided.
Description
technical field [0001] The invention relates to a packaging material, in particular to a cold-stamped pharmaceutical composite hard sheet. 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 large gap between the packaging quality of most domestic pharmaceutical products and developed countries. At present, medicinal blisters and polyvinyl chloride have existed in our country for many years. As a material for packaging drugs, it has good processing performance and light texture, but medicinal polyvinyl chloride has hidden dangers in safety. First of all, it contains chlorine, and it will be contaminated by chlorine in medicines with a long storage period, which will have a great impact on human body and health. Secondly, medicinal polyvinyl chloride is a water vapor and oxygen permeability. If the overdose is large, the impact on the stability of t...
