Packaging bag Aluminium Foil Manufacturers

There are many materials that can be used in food packaging bags, including various functional plastics, paper and aluminum. Many people are wondering why aluminum can be used as a material for food packaging? What are the characteristics of food packaging bags made of aluminum?
 
The aluminum used in the production of food packaging bags is usually laminated with aluminum foil and other materials. There are two main reasons why this is used:
 
First, the laminated process requires that the composite substrate must be in the form of a sheet, and metal aluminum can be easily processed into thin sheets because of its low hardness and good ductility. The commonly used
aluminum foil thickness is 0.005 mm ~ 0.009mm.
 
Secondly, aluminum is very active and is easily oxidized by oxygen in the air, forming a dense oxide Al2O3 protective film on the metal surface. Al2O3 is extremely stable in air environment and can prevent oxygen from continuing to oxidize metal aluminum. Of course, a packaging bag made of aluminum foil can use this layer of dense protective film to well isolate outside air from entering the bag, and play a role in preventing food from being oxidized and deteriorated.
 
Aluminum foil bag is a packaging product that combines the advantages of various packages in one package, with low cost and exquisite printing; the appearance of the product is opaque, silvery white, reflective, and has good barrier properties, heat sealability, light shielding properties, resistance to light High temperature, low temperature resistance, oil resistance, fragrance retention; non-toxic and tasteless; softness and other characteristics.
