How to choose medicinal cold stamping aluminum?
Firstly, let's explain what medicinal cold stamping aluminum is. Medicinal cold stamping aluminum, also known as cold aluminum, is a composite high barrier material mainly used in the packaging of tablet and capsule drugs, in direct contact with drugs. It can block water, oxygen, and sunlight for packaged drugs, extending their service life.
In the market, the commonly used pharmaceutical packaging materials are PVC hard sheets and PVC/PVDC composite hard sheets, which come in various colors and are affordable. Cold stamped aluminum, with its inherent metallic properties, has a barrier effect 60 times that of ordinary PVC, making it particularly suitable for packaging drugs that are prone to moisture.
So there are also many pharmaceutical packaging manufacturers in the market that produce medicinal cold aluminum products. As procurement or pharmaceutical customers, how should we choose?
Firstly, it is necessary to choose a manufacturer with production qualifications. As a type of packaging material, drug packaging materials come into direct contact with drugs, and the strength and production qualifications of their manufacturers are the first hurdle. Domestic production can refer to whether the manufacturer has a drug packaging production license, a national drug packaging production record, and whether it is a purification workshop.
After reading the paper materials, if you are still unsure, you can communicate with the manufacturer to test the sample machine, provide samples according to the requirements, and observe the actual testing effect. Generally, manufacturers can provide a certain number of samples or samples free of charge to customers for testing. For cold aluminum, there are two main tests: layering test and brewing test. Due to the fact that cold aluminum is a three-layer composite material, will there be delamination at the edge of the blister after the cold stamping process due to the adhesion between each layer. Secondly, for the brewing of the double zero bubble cap, can the material be made to not break and have a complete shape.
