Soft packaging aluminum foil mainly uses the metallic luster, light-proof, air-proof and certain strength and ductility of aluminum foil. Therefore, aluminum foil for food soft packaging is widely used in the packaging of various foods, such as dairy products, juice, meat, fish, coffee, chocolate and other perishable foods. It can maintain the freshness of food, extend the shelf life, maintain nutrients, and avoid pollution and deterioration.

Food grade aluminum foil is completely opaque to visible light, non-toxic and pollution-free, clean and oil-free on the surface, and the composition of aluminum foil meets the requirements of food packaging standards. At present, soft packaging foil mainly uses 1235, 8011, 8021, 8079 and other alloys, and the thickness is usually 0.02mm, 0.015mm, 0.009mm, 0.007mm, etc.

The overall production process of aluminum foil for soft packaging is: aluminum ingot smelting - casting and rolling - cold rolling - intermediate annealing - cold rolling - aluminum foil raw material - rough rolling - intermediate rolling - finishing rolling (double-combination) - slitting - finished product annealing - packaging.
