The wrinkle-free aluminum foil lunch box means that after the aluminum foil is stamped and formed, the wrinkles are minimal, and only four right-angle wrinkles are allowed. Wrinkle-free lunch boxes usually use aluminum foil as the raw material. They are cold-rolled and foil-rolled to produce aluminum foil of the required thickness. They are coated on both sides to form an aluminum foil master roll with a smooth surface, no pinholes, no dust particles, and no odor. After a special Equipment and molds are a one-time fully automatic cold stamping production process.

What are the characteristics of wrinkle-free lunch box materials made of 6061 aluminum alloy:
6061 aluminum alloy is an aluminum alloy with magnesium and silicon as the main alloy elements and the Mg2Si phase as the strengthening phase. It is a heat-treated aluminum alloy that can be strengthened. It has medium strength, high corrosion resistance, no tendency of stress corrosion cracking, good welding performance, and It has the advantages of unchanged corrosion resistance, good formability and process performance.
Aluminum foil lunch boxes have become a better alternative to plastic tableware in the catering and takeout markets due to their safety and hygiene, high and low temperature resistance, environmental protection, renewable energy saving, good sealing, convenience and speed. With people increasingly paying attention to environmental protection, aluminum foil lunch boxes have developed rapidly in recent years, and many companies have begun to seize the market, with bright future prospects.
