Aluminum foil for fast food boxes is a safe, hygienic and environmentally friendly material, and as a packaging product its main feature is excellent insulation performance, which can effectively isolate gas, water and light, thereby maintaining or increasing the preservation of food. period and freshness. Aluminum foil lunch boxes are generally made of 8011 aluminum foil or 3003 aluminum foil aluminum alloy aluminum foil and are formed by one-time stamping molds through high-speed punches and molds. A recyclable and environmentally friendly material that is continuously recycled. The heat conduction properties of aluminum foil are suitable for the requirements of fast heating for short voyages. Fast food boxes used on airplanes are mostly made of aluminum foil. As a raw material, aluminum foil lunch boxes also have high performance requirements.
The aluminum foil material of aircraft lunch boxes has many advantages such as harmlessness, high and low temperature resistance, environmental protection, and good sealing.
The aluminum foil material of airplane lunch boxes is an extremely thin sheet made of high-purity aluminum after multiple rolling processes. It is an excellent thermal conductor and light-shielding body. The surface has good light reflectivity and heat resistance (121 ℃) and low temperature resistance (-50 ℃), it has good shape under high and low temperatures, is non-toxic and tasteless, and meets the packaging standards of food and medicine.
