Different commodities have different requests for packaging materials, such as food packaging materials, which must conform to the hygienic standards of food packaging.

Moisture-proof packaging, vacuum packaging and air-filled packaging should have the function of preventing water vapor and oxygen from penetrating into the packaging bag and preventing the escaping of inert gas in the bag. The packaging of quick-frozen vegetables and frozen food should be cold-resistant.
For the packaging of greasy food, the utility of air tightness, oil resistance and ultraviolet penetration resistance is requested. For body-fitted packaging and shrinkage packaging, the plastic film should have certain shrinkage tension. For tea, tablets, biscuits and other packaging, the need for a high degree of moisture resistance, air tightness and shading functions, to adhere to its original flavor, and so on, this is also the most basic function, assuming that this function can not be done, then the packaging is intact and unnecessary.

It also implores that it has certain rigidity and stiffness, can adapt to the automatic packaging of packaging machinery, conform to the sealing and bag making of heat sealing machinery, and is easy to fill articles, easy to expose and other properties.
3. Transport and Storage Performance
Packaging boxes should have a certain compressive strength, to ensure that they are not easily damaged under ordinary pressure in the circulation area. The shape of packing boxes should be easy to stack and occupy less space. For example, some of our packing boxes can be folded to stop transportation, which can greatly reduce the transportation space and cost.
