8079 H18 aluminiumsfolie for kosmetisk emballasje

1. Introduksjon til 8079 H18 aluminiumsfolie for kosmetisk emballasje

8079 H18 Aluminum Foil for Cosmetic Packaging must protect sensitive formulations from moisture, oksygen, lys, aroma loss, and external contamination.

Samtidig, the packaging material needs to support printing, laminering, spalting, forsegling, and high-speed converting.

8079 H18 aluminiumsfolie is a high-barrier aluminum foil material suitable for flexible cosmetic packaging applications.

De 8079 alloy belongs to the 8xxx aluminum series, while H18 indicates a hard, strain-hardened temper with relatively high strength and dimensional stability.

In cosmetic packaging, 8079 H18 aluminum foil normally serves as the barrier layer rather than the complete package.

It can be laminated with PET, PE, CPP, papir, or other functional materials to form multilayer packaging structures.

The main value of 8079 H18 aluminum foil comes from the combination of barrierebeskyttelse, styrke, thin-gauge efficiency, overflatekvalitet, and converting performance.

Foil thickness, pinhole control, overflatetilstand, lamination structure, tetningssjikt, and converting process all influence the finished package.

2. Hva er 8079 H18 aluminiumsfolie?

2.1 Hva er 8079 Aluminiumslegering?

8079 is an aluminum alloy in the 8xxx serien, commonly used for aluminum foil applications that require a balance of strength, processing performance, og barriereegenskaper.

Typical published composition data for 8079 aluminiumsfolie include approximately 0.70–1.30% Fe og 0.05–0.30% Si, with other elements controlled according to the applicable material specification.

2.2 What Does H18 Mean?

H18 refers to a strain-hardened aluminum temper.

The material reaches the H18 condition through substantial cold working rather than full annealing.

Som et resultat, H18 foil generally has higher tensile strength and greater rigidity than soft O-temper foil.

The trade-off is lower elongation and flexibility.

This characteristic can be useful for converting processes where the foil needs good web stability, dimensional control, and resistance to tearing during slitting or laminating.

Imidlertid, H18 is not automatically suitable for every cosmetic packaging structure.

Applications requiring significant forming or deformation may require a softer temper.
