There are many kinds of materials that can be used in food packaging, including various functional plastics, paper, aluminum and so on. Many people wonder why aluminum can be used as food packaging material? What are the characteristics of food packaging made of aluminum foil? The aluminum used in the production of food packaging is usually compounded with aluminum foil and other materials.


There are two main reasons for this:

First, the composite process requires that the composite substrate must be in sheet form, while aluminum foil can be easily processed into sheet sheet because of its low hardness and good ductility. The thickness of commonly used aluminum foil is 0.005 mm ~ 0.009 mm.

Secondly, aluminum is very active and easy to be oxidized by oxygen in the air, forming a dense oxide Al2O3 protective film on the metal surface. Al2O3 is extremely stable in the air environment, which can prevent oxygen from continuing to oxidize aluminum. Of course, the packaging bag made of food packaging aluminium foil company can use this layer of dense protective film to well isolate the outside air from entering the inside of the bag, and play a role in preventing food from being oxidized.
