Aluminum foil lunch boxes can be processed into two types, wrinkled and wrinkle-free, using different processes
Aluminum foil lunch boxes are a widely used type of tableware. The thickness of aluminum foil lunch boxes is generally between , which can be divided into wrinkled and wrinkle-free. It can also be divided into disposable and reusable types. It is often called tinfoil lunch boxes. In fact, it is 3 series or 8 series aluminum ingot raw materials, which are cold-rolled or hot-rolled into aluminum foil mother rolls with uniform thickness, smooth surface, no pinholes, no dust particles, and no odor. It is a one-time fully automatic cold stamping production process using equipment and molds.
Aluminum foil lunch boxes are easy to process and form, convenient to seal, and food hygiene. Aluminum foil has good formability. During the process of stamping tableware, even in the wrinkled and curled parts, no cracks or breaks will occur. Aluminum foil of different shapes, thicknesses, alloys and heat treatment states can be selected as needed to accurately reflect the purpose of the product. Aluminum foil lunch boxes and containers can use lids made of the same material as aluminum foil, or they can use lids made of paper or other materials. The aluminum foil lids can be easily deformed and wrinkled to achieve good sealing, and have strong heat preservation and freshness preservation capabilities. They can avoid spillage or contamination during food storage and transportation. For large-scale food delivery companies and kitchen delivery, the automatic sealing equipment developed by aluminum foil lunch box manufacturers can be used to improve delivery efficiency, and the effect is significantly better than that of lunch boxes made of other materials.
