3004 Aluminum foil used in food packaging
Aluminum foil is made of electrolytic aluminum with a purity of 99.0%-99.7%. After repeated calendering, it forms a soft metal film. It has moisture-proof, air-tight and light-shielding properties. It does not shrink and deform at -73-371 °C, but also has fragrant, non-toxic and tasteless, and has strong protective properties, which makes the packaging materials less susceptible to damage by bacteria, fungi, and insects. These advantages are fully in line with the global food packaging standards and are unmatched by any other existing packaging materials, so It can become food-grade aluminum foil.
Features of 3004 Aluminum Foil
1. Excellent Punchability. Because the specific gravity of 3004 aluminum foil is lighter, compared to the products of the same size stamped from other materials, the stamping of 3004 aluminium alloy foil is also lighter, and the cost is effectively reduced while the formability is good.
2. Good Anodic Oxidation. The anodized surface-treated 3004 aluminum foil effectively improves the hardness and abrasion resistance of the aluminum foil and also gives the surface of the 3004 aluminium alloy foil a bright and colorful color.
3. Other Characteristics. Of course, 3004 aluminum foil also has the excellent barrier properties of aluminum foil itself, and strong light-shielding, air-tightness, oxidation resistance, waterproof, moisture-proof, non-toxic and tasteless, etc., meeting food packaging standards.
