OPA AL PVC Alu Alu Cold Forming Foil For Blister Packaging

OPA AL PVC Alu Alu cold forming foil for blister packaging is a multi-layer composite material commonly used in pharmaceutical packaging, which can provide excellent protection for drugs from the effects of light, air and moisture.

OPA/AL/PVC is a common structural configuration of this cold forming foil, and each layer of material has its specific function:

– OPA (Oriented PolyAmide): Usually used as the outer layer, it has good mechanical strength and toughness, can withstand stretching and impact during production, and provides a good printing surface.

– AL (Aluminum): The middle layer, the aluminum foil provides excellent gas and light barrier properties, helping to extend the shelf life of drugs and protect them from external environmental factors.

– PVC (Polyvinyl Chloride): The inner layer, in direct contact with the drug, has good heat sealing properties and ensures the sealing of the package.

This multi-layer structure makes Alu Alu cold forming foil very suitable for blister packaging (also known as blister packaging), especially for pharmaceutical products that are sensitive to moisture, oxygen or require light protection. By using such high-performance packaging materials, the quality and effectiveness of drugs can be effectively protected while meeting the strict requirements of the pharmaceutical industry.

Cold forming process

– No heating required: Direct stamping and forming through the mold to avoid the impact of high temperature on drugs (such as volatile components) and reduce energy consumption.

High-precision forming: Blisters of complex shapes can be manufactured to improve the packaging aesthetics and drug protection.

Advantages of OPA AL PVC Alu Alu cold forming foil for blister packaging:

– Independent unit sealing: Each blister forms an independent sealed unit, and the drugs in other blisters will not be affected when taking the drugs.

– Moisture-proof, oxygen-proof, and light-proof: The aluminum foil layer completely isolates the external environment and extends the shelf life of drugs, especially for solid drugs such as tablets, capsules, and powders.

– Increase product added value: The appearance is simple and generous, and the market competitiveness of drugs is enhanced.

OPA/AL/PVC Alu-Alu cold forming foils have become the mainstream choice for drug blister packaging due to their excellent barrier properties and forming process. In the future, with the tightening of environmental protection regulations and the development of intelligent technology, material innovation and functional integration will become the key direction of industry development.
