vacuum freezer bags
The barrier property is an important index to evaluate the permeability of vacuum freezer bags to porous objects, and it is also a basic function that vacuum freezer bags must have, especially the packing material which requires a higher barrier property of food, such as packaging materials need to have high barrier properties to prevent oxygen, water vapor, microorganisms, acids, alkalis, and other corrosive solvents and other substances infiltration, while anti-pollution, moisture-proof role, maintain performance inside the package. The moisture-proof properties keep the vacuum freezer bags' internal environment stable and protect the contents, thereby extending the shelf life of the food.
