Food Container Foil 3003 3004 8006 8011 0.03-0.2mm For Lunch Box

Aluminum foil containers are a widely used tableware. The thickness of aluminum foil lunch boxes is generally 0.03 mm to 0.20 mm, and they are divided into two types: wrinkled and wrinkle-free. It can also be divided into disposable and reusable. In China, it is often called a tinfoil lunch box. In fact, it is 3 series or 8 series aluminum ingot raw materials, which are cold-rolled or hot-rolled into aluminum foil rolls with uniform thickness, smooth surface, no pinholes, no dust particles, and no odor. Special equipment and molds are used for one-time automatic cold stamping.

3003 aluminum foil is one of the commonly used lunch box materials. The tensile strength is 140-170 MPa, and the elongation is ≥9%. It has higher tensile strength and elongation than 1 series and 8 series aluminum lunch box materials, ensuring a low breakage rate when stamped into lunch boxes.
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 finished product rate of lunch boxes made of 3003-H24 aluminum foil can be as high as 95% or more.

3004 aluminum foil is used for food packaging, food box materials, aluminum foil container foil, etc.
3004 aluminum foil has high hardness, good load-bearing capacity, and better stamping effect than 3003 aluminum foil. It can be used for aluminum foil lunch boxes, and the product is hygienic.

Yongsheng Aluminum is the raw material manufacturer of 8011 container aluminum foil. 8011 aluminum foil has the advantages of a smooth surface, no oil stains, bright lines and other inclusions, product safety and hygiene, and high elongation.

8006 aluminum foil is a representative of the special aluminum foil for aerospace lunch box materials. The tensile strength is 125-135 MPa. The edge of the stamped lunch box has no wrinkles, and the appearance is high-end and beautiful.
Another container foil material is 8011 aluminum foil, which has a tensile strength of 120-170 MPa and an elongation of more than 8%. The mechanical parameters of these two lunch box materials are very different. However, the elongation and cup convexity of 8006 aluminum foil for lunch box materials are higher than those of 8011 and 3003 aluminum foils.
