1. Introduction to 8079 H18 Aluminum Foil for Cosmetic Packaging
8079 H18 Aluminum Foil for Cosmetic Packaging must protect sensitive formulations from moisture, oxygen, light, aroma loss, and external contamination.
At the same time, the packaging material needs to support printing, laminating, slitting, sealing, and high-speed converting.
8079 H18 Aluminum Foil is a high-barrier aluminum foil material suitable for flexible cosmetic packaging applications.
The 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, paper, or other functional materials to form multilayer packaging structures.
The main value of 8079 H18 aluminum foil comes from the combination of barrier protection, strength, thin-gauge efficiency, surface quality, and converting performance.
However, the final packaging performance does not depend on the alloy alone.
Foil thickness, pinhole control, surface condition, lamination structure, sealing layer, and converting process all influence the finished package.
2. What Is 8079 H18 Aluminum Foil?
2.1 What Is 8079 Aluminum Alloy?
8079 is an aluminum alloy in the 8xxx series, commonly used for aluminum foil applications that require a balance of strength, processing performance, and barrier properties.
Typical published composition data for 8079 aluminum foil include approximately 0.70–1.30% Fe and 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.
As a result, 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.
However, H18 is not automatically suitable for every cosmetic packaging structure.
Applications requiring significant forming or deformation may require a softer temper.
