Aluminum foil packaging bag has metallic luster, good light avoidance, high reflective ability to heat and light, metallic luster and reflection ability can improve the brightness of printing color; good isolation, strong protection, impermeable gas and water vapor, prevent moisture from moisture and vaporization, and are not vulnerable to bacteria and insects; shape stability is good, it is unacceptable. The influence of humidity change. It is easy to process. It can print aluminum foil bags, color difference, embossing, surface coating, gluing and lacquer, etc. the composite aluminum foil bag also has the advantages of isolation.

The production process of aluminum foil bag is simple and tedious, and the overall production process is: aluminum ingot smelting - casting rolling - cold rolling - cold rolling - cold rolling - aluminum foil wool - rough rolling - middle rolling - finishing rolling (double) - cutting - aluminum foil finished annealing - composite bag - aluminum foil bag finished product - packaging. In this process, the whole process starts from the aluminum foil to the processing of the plain foil, and then in the compound bag making. In order to save cost and time, aluminum foil bag enterprises usually choose to purchase aluminum foil directly, and then make composite material bags.
