Why Cold Formed Alu Alu Foil Is Suitable For Blister Packaging?
There are many materials used in the packaging of medicines, from the original paper and plastic to the present metal pharmaceutical aluminum foil. With the progress of technology, people have carried out more detailed divisions on the packaging of drugs, what kind of aluminum foil corresponds to what kind of drugs. Among aluminum foil pharmaceutical packaging, Cold-formed Alu Alu Foil has become popular in recent years and has a good performance in blister packaging.
We all know that the storage of medicines is very sensitive to the environment. Sometimes the packaging is intact and the capsules are damaged. The reason is that some pharmaceutical packaging materials do not have a very good barrier to air, gas, and light. In order to meet the barrier performance of packaging, Alu Alu Foil has been widely used in the pharmaceutical packaging industry. Alu Alu foil is also known as cold formed foil/cold forming foil.
Alu Alu Blister Foil or CFF is a multilayer structure composite film composed of OPA (nylon), aluminum Foil, and PVC film, which is combined together by processing technology and adhesive. Alu Alu foil has several common specifications and is also the composite form of various layers.
OPA 25 microns/adhesive/aluminum foil 45 microns/Adhesive /PVC 60 microns
OPA 25 microns/adhesive/aluminum foil 50 microns/Adhesive /PVC 60 microns
OPA 25 microns/adhesive/aluminum foil 60 microns/Adhesive/PVC 60 microns
Alu Alu Foil on pharmaceutical packaging has strong hygroscopicity, is sensitive to light, and can protect drugs from atmospheric water vapor, oxygen, and strong light. Alu Alu Foil is completely formed by cold forming technology in the manufacturing process. Has many excellent properties, it provides 100% protection against light, oxygen, water vapor, and other gases. And the formability, stability is a good performance. In terms of appearance, the silver surface gloss can make Alu Alu Foil Packaging have a better aesthetic feeling.
In general, the PVC film in the cold-formed foil is used as the contact layer to seal the aluminum cover foil on the pharmaceutical blister package.
PVC after the cold forming process is very stable, will not be deformed, because it is very hard, so after the cold forming process is completed to help the cavity to maintain its shape.
Most of the pharmaceutical packaging materials used by drugs on the market are required to have good barriers, and some special drugs also require light avoidance. And the excellent characteristics of Alu Alu Foil in medicinal packaging will be more widely used in packaging in the future.
