Cold-formed medicine foil is one of the indispensable key materials in modern pharmaceutical packaging. Its excellent barrier properties and excellent forming ability make it an ideal choice for protecting the quality of medicines and extending the shelf life. By combining high-strength aluminum alloys and advanced coating technology, cold-formed medicine foil can not only resist the damage of oxygen, moisture and light, but also adapt to complex packaging design requirements, providing comprehensive protection for the safety and stability of medicines.

Aluminum foil base alloy for cold-formed medicine foil: 8021-O state aluminum foil, 8079-O state aluminum foil, thickness of 0.025-0.08mm; with high cupping value, high heat sealing strength, no pinholes, good sealing and other advantages. It is a supplier of raw materials for cold-formed medicine aluminum foil for various foreign pharmaceutical packaging companies.

Structure of cold-formed aluminum foil:
Cold-formed aluminum foil is usually a multi-layer composite structure, which is composed of aluminum foil and other barrier materials to ensure that the packaging has excellent mechanical strength and barrier properties. The common structure is three layers:

OPA (nylon) layer + aluminum foil layer + PVC (or PP) layer

Nylon (OPA) layer: the outer layer material, which provides high tensile strength and impact resistance for cold-formed aluminum, making it not easy to break during the cold forming process, and also provides certain barrier properties.

Aluminum foil layer (Al): the middle layer, usually 45-60 micron thick pure aluminum foil, is the main barrier layer, with extremely high moisture resistance, oxygen resistance and light resistance, effectively protecting the stability of the drug.

Polyvinyl chloride (PVC) or polypropylene (PP) layer: the inner layer material, directly in contact with the drug, has good heat sealing and chemical resistance to ensure the safety of the drug and the sealing of the packaging.

8021 8079 cold-formed aluminum foil performance advantages:
1. Excellent barrier properties: effectively block gases (such as oxygen, water vapor) and light radiation, protecting drugs from external influences.
2. High sealing: compounded with a variety of materials to form a firm sealing structure to ensure the stability and safety of drug packaging.
3. Excellent mechanical properties: high strength and high toughness, heat and low temperature resistance, able to withstand various stresses and deformations.
4. Easy to process and form: suitable for various processing techniques, meet different drug packaging needs, and adapt to automated packaging equipment.
5. High safety: non-toxic, odorless, environmentally friendly, will not pollute drugs, and has good chemical stability.
6. Protect drug quality: keep drugs dry and moisture-proof, extend shelf life, and good light-shielding properties to prevent deterioration.
7. Easy to carry: light and easy to carry, convenient for patients to use.
