The role of food packaging bags

Physical protection
The food stored in the bag needs to avoid extrusion, impact, vibration, temperature difference, etc.
2. Shell protection
The outer casing separates food from oxygen, water vapor, stains, etc. Leakage prevention is also a necessary factor in packaging design. Some packages include desiccants or deoxidizers to extend shelf life. Vacuum packaging or evacuating the air in the bag is also the main food packaging method. Keeping the food clean, fresh and safe during the shelf life is the primary function of the bag.
