Flexible packaging foil is an aluminum foil material used for packaging food, medicine, daily necessities, etc. It is widely used in the food flexible packaging industry because of its non-toxic and tasteless, light-shielding, heat-insulating, anti-corrosive, high moisture-proof and low-cost characteristics.
Flexible packaging foil is usually used in combination with plastic film or paper. Commonly used alloy grades include 1235 aluminum foil, 8011 aluminum foil, 8079 aluminum foil, etc. Packaging aluminum foil can be used to package milk powder, puffed food, meat products, condiments and other foods, as well as medicines, cosmetics and other products through lamination, coloring, printing, printing, coating and other processes.
