Food plastic packaging bags can be divided into: general food packaging bags, vacuum food packaging bags, inflatable food packaging bags, poached food packaging bags, retort food packaging bags and functional food packaging bags according to the scope of their application.
The role of food plastic packaging bags.

Physical protection
The food stored in the bag needs to avoid extrusion, impact, vibration, temperature difference and the like.
2. Shell protection
The outer casing separates food from oxygen, water vapor, stains, etc. Leakage 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 package.
3. Packaged into the same package
Stuffing a small item of the same kind into a package is a good way to save volume. Powders and granular objects need to be packaged.
4. Communicate information
Packaging and labels tell people how to use, transport, recycle or treat packaging or food.
5. Marketing
Marketing often uses box labels to encourage potential buyers to buy goods. Packaging design has become a pivotal and ever-changing phenomenon for decades. Marketing communication and graphic design are applied to the outer box and the highlights of the sales show (for some reasons).

6. Security
Packaging can play an important role in reducing transportation safety risks. The bag also prevents food from being returned to other items. Food packaging also reduces the likelihood of food being stolen. Some food packaging is very strong and has anti-counterfeiting labels to protect the interests of the business from loss. The bag can have a laser logo, special color, SMS authentication and other labels. In addition, in order to prevent theft, the retailer has an electronic surveillance label attached to the food packaging bag, and the consumer receives the outlet of the store for degaussing.
Convenience
Packaging may be easy to add, handle, stack, display, sell, open, reload, use and reuse.
8. Partial control
A single package helps you get the most out of your situation. For example, the amount of stock can be known by loading salt into the package. It also makes it easy to calculate recent sales, such as dairy companies sending and recycling milk bottles instead of letting consumers fill themselves.
