Features of vacuum packaging:

1 Excluding the local air (oxygen) in the packaging container can effectively prevent food from decaying. Can effectively prevent the exchange of substances in the package;

2 Use packaging materials with excellent barrier properties (air tightness) and strict sealing technology and requirements. It can prevent food from losing weight and losing taste, and can prevent secondary pollution. Accelerate the conduction of heat;

3 The gas inside the vacuum packaging container has been removed. This can improve the heat sterilization efficiency and avoid the rupture of the packaging container due to the expansion of the gas during the heat sterilization.

PE is a plastic bag divided into high pressure and low pressure. High pressure sound, no low pressure, general plastic bags are PE, and vacuum bags (called PA) are not completely nylon. The special vacuum packaging bag is PA+PE, which is nylon polyg Ethylene

Every day, the film bags we are in contact with are actually leaking. If you want to not leak, technically use the "composite" or "coating" method to thicken, you can keep airtight for a long time.

The PE bag is the code name of “polyethylene” plastic. If it reaches the thickness of 20 wire, it can also be used as a vacuum bag.

You said "vacuum bag", which material is a lot. It can be produced by a method of compounding and coating, or it can be made of a film of polyethylene, polypropylene or the like.

The leaking of the vacuum bag may be that the film is too thin or is pinched by a pointed object.
