8021 aluminum foil is one of Mingtai Aluminum’s key products. It is produced in thicknesses ranging from 0.018mm to 0.2mm, and widths can be controlled from 100mm to 1650mm according to customer requirements. 8021 aluminum foil is a primary product for pharmaceutical packaging and battery soft-pack aluminum foil. It possesses excellent moisture-proof properties, light-blocking capabilities, and extremely high barrier properties. It is non-toxic, odorless, safe, and hygienic. After lamination, printing, and adhesive coating, the aluminum foil is widely used as a packaging material.
1. Safe and non-toxic, water-resistant (Grade A), high cupping value;
2. Strong mechanical properties, high burst resistance, strong puncture and tear resistance;
3. Excellent moisture-proof performance, light-blocking ability, and high barrier properties;
4. Clean surface, uniform color, no spots, no oil stains, smooth and free of pinholes;
5. Multiple tests for bacteria, mold, etc., heavy metals not exceeding 0.25 parts per million, strictly adhering to industry standards to ensure safety and hygiene.
Differences between 8021 aluminum foil and 8079 aluminum foil
Feature
8021 Aluminum Foil
8079 Aluminum Foil
Main Composition
Silicon (Si) ≤ 0.15%, Iron (Fe) 1.2–1.7%
Silicon (Si) 0.05–0.30%, Iron (Fe) 0.7–1.3%
Core Advantages
High barrier properties, extremely few pinholes, excellent moisture-proof and light-blocking performance. Known as “high-performance aluminum foil.”
High strength, good ductility, easy formability, outstanding stamping performance.
If your top priority is sealing, moisture resistance, and light blocking—i.e., ultimate protection—especially in pharmaceutical, premium food, or lithium-ion battery packaging, then 8021 is the better choice.
If your packaging requires complex stamping, deep drawing, or forming processes that demand high material ductility—such as in certain pharmaceutical blister packs—then 8079 would be more suitable.
