Mingtai packaging aluminum foil manufacturing advantages
The aluminum foil used in food packaging bags is a flattened metal aluminum tool that can be used in the kitchen for cooking, holding food, or making materials that can be easily cleaned.
Foods packaged in aluminum foil on the market are generally reheatable and shelf-stable. Most of the aluminum foil used in food processing has a bright side and a gray dull side. Aluminum foil paper for food can be used to wrap food on both sides. It is usually recommended to wrap food on the shiny side to increase thermal conductivity.
Why do food packaging bags use aluminum foil? This is because metal aluminum will be oxidized by oxygen, forming a dense oxide Al2O3 protective film on the metal surface to prevent oxygen from continuing to oxidize metal aluminum. Of course, packaging bags made of aluminum foil use this layer The dense protective film can better isolate the outside air from entering the food packaging bag, preventing the food from being oxidized and spoiled.
On the other hand, aluminum foil has good ductility, excellent separation performance, strong corrosion resistance, and good printing adaptability.
Food packaging bags are not simply made of aluminum foil, but are made of composite materials. This composite material is made of aluminum foil and nylon. Some are made of four-layer co-extruded film. In some packaging When it comes to food, it is often a multi-layered composite material.
