Correct the problem:

Evacuating and vacuuming are actually the same concept. In operation, they are generally called vacuuming. They are both a kind of food that is placed in a vacuum machine to extract air and seal it. Packaging technology will sterilize food before or after bagging, and there is no real difference.

The packaging technology of inflating the inside of a bag is called inflating.

So, the difference is obvious. Vacuum packaging is to extract as much air as possible from the packaging bag, while inflation is to replace the air in the bag with inert gases such as nitrogen or carbon dioxide. The purpose is to maximize the Reduce the contact between food and air, slow down the oxidation process of food, and avoid rapid deterioration of food.
