Moisture-proof aluminum foil bags have metallic luster, good light protection, and high reflective ability to heat and light. The metallic luster and reflective ability can improve the brightness of printed colors; they have good isolation and protection, are impermeable to gas and water vapor, and prevent internal The material absorbs moisture and vaporizes, and is not susceptible to bacteria and insects; it has good shape stability and is not affected by changes in humidity. It is easy to process and can be used for printing, color difference, embossing, surface coating, gluing and painting on aluminum foil bags. Composite aluminum foil bags also have advantages such as insulation.
The production process of aluminum foil bags is simple and cumbersome. The overall production process is: aluminum ingot smelting-casting and rolling-cold rolling-intermediate annealing-cold rolling-aluminum foil wool-rough rolling-intermediate rolling-finishing Rolling (double closing) - slitting - annealing of finished aluminum foil - compounding - bag making - finished aluminum foil bag - packaging. In this process, it is the whole process from aluminum foil wool to processing of plain foil, and then composite bag making. In order to save costs and time, companies that produce aluminum foil bags generally choose to directly purchase aluminum foil films and then composite materials to make bags.
