What is a vacuum bag?
Vacuum bags are trendy in meat food packaging, the material of vacuum bags is NY/PE or NY/AL/PE mainly. Nylon is very soft and has good tensile properties, AL is lightproof and moisture-proof, and PE is food grade which can contact food directly.
You just need to remove the air from the bag, then the sealed bag reaches a predetermined degree of vacuum.
The main function of the vacuum bag is to remove oxygen to help prevent food spoilage. The principle is also relatively simple because the activities of microorganisms mainly cause the mildew and spoilage of food, and the survival of most microorganisms (such as mold and yeast) requires oxygen. , and vacuum packaging uses this principle to pump out the oxygen in the packaging bag and food cells so that the micro-materials lose the “survival environment”.
