Aluminum foil container is made of aluminum foil with certain strength and toughness after stamping and forming. It is a new type of food and beverage packaging and distribution container. Compared with other materials, it is of light weight, moisture-proof and anti-corrosion, and long shelf life.
Generally speaking, in the alloy composition of food container aluminum, various toxic elements must meet the requirements, such as: Pb≤0.2mg/kg, Cd≤0.02mg/kg, As≤0.04mg/kg, and some countries and regions are also toxic to Ni, Cr6+, etc.
At the same time, some countries and regions also put forward specific requirements for toxic elements such as Ni and Cr6+. It should comply with local food hygiene standards, such as FDA certification in the United States and Kosher certification in kosher regions.
The common alloys for food container are 8011, 8006, 30004 and 3003. 8011 aluminum foil has good molding performance and its strength is generally 120Mpa, which is suitable for non-wrinkle food tray. It is of low processing cost, but it is of low strength and low alloy content.
8006 aluminum foil features medium and high strength, generally 140Mpa, which is suitable for the production of wrinkle-free food container. It is not suitable to add a large amount of recycled aluminum. The strength is medium, and the thickness of the aluminum foil is thick, which is not conducive to reducing the cost of food container.
3004 alloy has high strength, up to 240 Mpa, which is suitable for punching large dinner plates. It has high alloy content, which can be added with large quantities of the recycled aluminum. It is of insufficient elongation, so it is difficult to meet deep drawing conditions. When a large amount of recycled aluminum is used, it is easy to cause the heavy metal content to exceed the standard.
3003 aluminum foil is well known for medium and high strength, generally 14OMpa, which is suitable for the production of ultra-thin and wrinkled lunch container. It beneficial to reduce the weight of lunch boxes and reduce costs.
Both 3003 and 8011 are the common choices for making food tray. Aluminum container foil 3003 h24 has a lower elongation in relative t0 8011, but it has higher tensile strength. It has two production processes: continuous casting and rolling rout and casting and rolling route.
Haomei Aluminum has introduced advanced Zhuoshen Foil Rolling Mill and ANDRITZ Profile Roller, which provides a guarantee for the realization of high-quality aluminum foil, and strictly controls the production of 3003 aluminum foil to make the product performance reach the international advanced level.
