At present, food containers are rapidly entering the fields of aviation food, home cooking and large chain cake shops around us. And these aluminum foil lunch boxes are made of 3003, 8011, 1100 aluminum foil and other 3 series, 8 series or 1 series aluminum foil lunch box materials, usually with a thickness between 0.03mm ~ 0.20mm.
1 series aluminum foil represented by 1100 aluminum foil contains 99% Al, retaining the advantages of pure aluminum such as excellent ductility. In fact, aluminum foil will be treated with a surface coating, which can be directly heated on a gas stove or baked in a microwave oven without generating harmful substances. In addition, 1 series aluminum foil has simple processing technology and low cost, which is very suitable for mass production of household foils with fast update speed and large consumption, and can be recycled without pollution.
3003 aluminum foil is one of the commonly used lunch box materials. Its tensile strength is 140-170Mpa and the elongation is ≥9％. It has higher tensile strength and elongation than both 1 series and 8 series aluminum lunch box materials, ensuring low fracture rate when stamped into a lunch box. Therefore, 3003 aluminum foil can well meet the production needs of three-cavity, multi-cavity or complex special-shaped lunch boxes. It is worth mentioning that the yield of lunch boxes made of 3003-H24 aluminum foil can be as high as 95% or more.
8006 aluminum foil as a representative is the exclusive aluminum foil for aerospace lunch box materials. It has a tensile strength of 125-135Mpa. The edges of the stamped lunch box have no wrinkles, and the appearance is high-grade and beautiful. For another lunch box material 8011 aluminum foil, which has a tensile strength of 120-170Mpa and an elongation greater than 8%, the difference in mechanical parameters between this two lunch box materials is small. However, 8006 aluminum foil for lunch box material has higher elongation and cup convexity than 8011, 3003 aluminum foil.
