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 of3004 aluminium alloy foilis 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.
