What gauge is aluminum foil food packaging? The range of food aluminum foil packaging bags is wide, including facial mask aluminum foil bags, coffee aluminum foil bags, and tea aluminum foil bags,etc.In fact, the production of food aluminum foil packaging bags must follow a basic principle, that is, its thickness should not be too thick. First of all, it is divided into two types: transparent and opaque in appearance. A transparent packaging bag means that the food inside can be seen from the outside, while an opaque packaging bag cannot see the food inside.The production of food aluminum foil bags must pay attention to the appropriate thickness, that is, it should not be too thick or too thin. A packaging bag that is too thin will not have the protective effect of the packaging. It will easily be damaged if it is torn by external forces.For example, when the oily food is wrapped in a thin aluminum foil packaging bag, the oil stains will penetrate through the inside to the outside, which will affect the food quality. In addition, food aluminum foil bags that are too thin are greatly affected by the environment, and are easily decomposed under sun exposure and rain soaking.Food packaging bags that are too thick also have many disadvantages. Too thick packaging bags are easier to affect the shelf life of food, which means that it can shorten the storage time of food. Apart form that, too thick aluminum foil packaging are also very harmful to the environment. They may not rot and dissipate after many years.In short, the aluminum foil sheet thickness should not be too thick or too thin. Haomei aluminium foil food packaging is usually 0.006-0.2 mm. The commonly used alloys are 1145, 1235, 1100, 3003, 8011, 8079, etc. , meeting the main international standards like ISO,SGS,MTC,etc.
