What is ALU-ALU base foil

ALU-ALU base foil is one of the core materials for cold-formed aluminum foil pharmaceutical packaging, and is mainly used as the base layer in pharmaceutical blister packaging. The material is widely used to protect highly sensitive drugs, such as tablets, capsules and injections, due to its excellent barrier properties and molding characteristics.

Features of cold-formed aluminum foil:

1. Excellent barrier properties: The aluminum foil layer completely blocks light, oxygen and water vapor to prevent drug deterioration.

2. Cold stamping molding performance: The OPA layer brings ductility, allowing the material to be molded into complex shapes without cracks during cold stamping.

3. Physical and chemical stability: It has good chemical resistance to ensure that the packaging does not react with the drug.

4. Good heat sealing performance: The heat sealing strength between the inner layer and the sealing film is high to ensure the airtightness of the packaging.

5. Wide range of applications: Suitable for a variety of drugs with high barrier performance requirements, such as antibiotics, hormones and vitamins.
