Is the aluminum foil packaging bag made of metal?
Aluminum foil packaging bags usually refer to aluminum plastic composite vacuum packaging bags, which are composed of various plastic films and aluminum foil composite combinations. They are a type of composite packaging bag containing metal components, mostly adopting a four layer structure, and have good water and oxygen resistance functions. Suitable for moisture-proof, light proof, and vacuum packaging of large precision mechanical equipment, chemical raw materials, and pharmaceutical intermediates.
Is the aluminum foil packaging bag insulated?
Because aluminum foil is a metal, it itself conducts electricity. However, the material structure of aluminum foil packaging bags is usually PET/AL/CPP, PET/AL/PE, BOPP/AL/PE, PET/AL/NY/CPE. From this, we can see that aluminum foil has been wrapped in multiple materials on the inner layer, so aluminum foil packaging bags can be considered as insulation.
