What is cold-formed aluminum foil?

Cold-formed aluminum foil is an aluminum foil product processed by cold stamping and forming process. It is a high-performance composite packaging material widely used in the pharmaceutical industry, especially in blister packaging (Blister Packaging), for packaging tablets, capsules and other medicines that require high protection.

What is alu alu foil?

Alu Alu Foil, also known as double aluminum foil, is a high-performance composite packaging material mainly used for blister packaging in the pharmaceutical industry, such as tablets, capsules and other medicines. Alu alu foil is widely used in product packaging with strict storage conditions due to its excellent barrier properties and mechanical strength.

Is cold-formed aluminum foil alu alu foil?

Both cold-formed aluminum foil and alu alu foil are produced by cold forming process, and have consistent product structure. Both are the same aluminum foil packaging material.

Structure of cold-formed aluminum foil

Cold-formed aluminum foil is usually composed of three layers of materials:
1. Outer layer: Nylon (PA)
Provides tear resistance and high-strength support, and enhances structural toughness.
2. Middle layer: aluminum foil
Provides excellent shielding performance, blocks external factors such as light, oxygen, and water vapor, and protects the inner packaged medicines.
3. Inner layer: polyvinyl chloride (PVC) or polypropylene (PP)
Has good sealing performance, contacts with medicines, ensures that the packaging is non-toxic, hygienic and has heat sealing capabilities.

Structure of Alu Alu Foil

Alu Alu Foil is usually composed of the following three layers of materials:
1. Outer layer: Nylon (PA)
– Provides excellent tear resistance and mechanical strength, and enhances the toughness and stability of the packaging.
2. Middle layer: aluminum foil
As the core barrier layer, it has extremely high barrier properties and can completely block external factors such as water vapor, oxygen, and light.
3. Inner layer: polyvinyl chloride (PVC) or polypropylene (PP)
As a heat-sealing layer, it is in direct contact with the product to ensure sealing and non-toxicity.

Characteristics of cold-formed aluminum foil for pharmaceuticals

Excellent barrier properties

With the high barrier properties of aluminum foil, it can effectively protect drugs from moisture, oxygen and light, and extend the shelf life of drugs.

High puncture resistance and mechanical strength

The cold forming process gives the packaging high tear resistance and strength, which is suitable for protecting fragile drugs.

Environmental characteristics

Since cold aluminum packaging can reduce dependence on other plastic materials and aluminum foil is recyclable, it is more environmentally friendly.
