The manufacturers of aluminum foil bags introduce the physical protection and shell protection of food packaging bags
1. Physical protection: the food stored in the packaging bag needs to avoid extrusion, impact, vibration, temperature difference and other phenomena.
2. Shell protection: the shell can separate food from oxygen, water vapor and stains. Anti leakage is also a necessary factor in the design of aluminum foil bag packaging. Some packages contain desiccants or deoxidizers to extend shelf life. Vacuum packaging or removing air from packaging bags is also the main method of food packaging. Keeping food clean, fresh and safe within the shelf life is the primary function of aluminum foil bags www.dgbpk.com/
