The function of food packaging bag

Physical protection

The food stored in the packing bag shall be free from extrusion, impact, vibration, temperature difference, etc.

Shell protection

The shell can separate the food from oxygen, water vapor, stain, etc., and anti leakage is also a necessary factor for packaging design. Some packages include desiccants or deoxidizers to extend the shelf life. Vacuum packaging or air extraction 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 the packaging bag.

Same package

It's a good way to save volume to pack the same kind of small objects into a package. Powder and particles need to be encapsulated.

Convey information

Packaging and labeling 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 an important and changing phenomenon for decades. Marketing communication and graphic design applied to outer packing box and (for some reasons) highlights of sales presentation.


Packaging can play an important role in reducing transportation safety risks. Packing bags also prevent food from being put into other products. 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 logo, special color, SMS authentication and other labels. In addition, in order to prevent theft, the retailer pastes electronic monitoring labels on the food packaging bags, so that consumers can get the outlet of the store for demagnetization.


The packaging may be easy to add, load, unload, stack, display, sell, open, reload, use and reuse.

Partial control

A single package helps you stay in control. For example, the quantity of salt in stock can be known when it is packed. It also makes it easy to calculate sales, such as milk companies sending and recycling milk bottles, rather than letting consumers fill them themselves.
