What requirements should food packaging bags meet

　　What requirements should food packaging bags meet?

　　1. Physical protection of food packaging bags

　　The food stored in the packaging bag needs to avoid extrusion, impact, vibration, temperature difference and other problems.

　　2. Shell protection

　　The shell of food packaging bag can separate food from oxygen, steam and stains, and anti leakage is also a necessary factor in packaging design. Some packages contain desiccants or deoxidizers to extend the shelf life. Vacuum packaging or air extraction from packaging bags are also the main food packaging methods. The main function of the packaging bag is to keep the food clean, fresh and safe within the shelf life.

　　3. Package or load the same product package

　　It is a good way to save volume for food packaging bag manufacturers to stuff similar small things into packaging bags. Powder and granular objects need to be sealed.

　　4. Exchange of information

　　The packaging and labels of food packaging bags tell us how people package, or how food is used, transported, recycled or treated.

　　5. Food packaging bag marketing

　　The label on the box is usually used for marketing to encourage potential buyers to buy. For decades, packaging design has become an important and changing phenomenon. Marketing communications and graphic design apply to the focus of packaging and (for some reason) sales presentations.

　　6. Safety

　　The packaging design of food packaging bag manufacturers can play an important role in reducing the risk of enterprise transportation network security management. Packaging can also prevent food from falling into other related commodity economies. Food packaging technology can also reduce the possibility of food theft. In some countries, food and drugs are packed firmly and have anti-counterfeiting labels, which can protect the environment and protect the interests of enterprises from losses. The packaging bag can be labeled with laser identification, special color, SMS authentication, etc. In addition, in order to guard against theft, retailers pasted electronic data monitoring labels on food packaging bags, waiting for consumers to take the outlet of the store for degaussing.
