Food packaging bag function:
The food stored in the packaging bag should avoid squeezing, impact, vibration, temperature difference and other phenomena.
The shell can separate food from oxygen, water vapor, stains, etc., and leakage prevention is also a necessary factor in packaging design. Some packages include desiccant or deoxidizer to extend shelf life. Vacuum packaging or removing the air from the packaging bag is also the main food packaging method. Keeping food clean, fresh and safe during the shelf life is the primary function of the packaging bag.
Stuffing small objects of the same type into one package is a good way to save volume. Powder and granular objects need to be encapsulated.
Packaging and labels tell people how to use, transport, recycle, or dispose of packaging or food.
Marketing often uses box labels to encourage potential buyers to buy goods. Packaging design has become a pivotal and constantly changing phenomenon for decades. Marketing communications and graphic design are applied to the outer box and (for some reasons) the highlights of the sales presentation.
Packaging can play an important role in reducing transportation safety risks. Packaging bags can also prevent food from being included in other commodities. Food packaging can also reduce the possibility of food being stolen. Some food packages are strong and have anti-counterfeiting marks, which protect the interests of businesses from loss. The packaging bag can have laser marking, special color, SMS authentication and other labels. In addition, in order to prevent theft, the retailer puts an electronic monitoring label on the food packaging bag, and waits for the consumer to get it at the outlet of the store for demagnetization.
The packaging may be easy to add, load, unload, stack, display, sell, open, repack, use and reuse.
