Food vacuum packaging bag
Vacuum bags are also called decompression packaging, which is to extract all the air in the packaging container and seal it to maintain a high degree of decompression in the bag. The scarcity of air is equivalent to the effect of low oxygen, so that microorganisms have no living conditions, so as to achieve fresh fruit and no disease. purpose of occurrence.
Applications include vacuum packaging in plastic bags, aluminum foil packaging, glassware packaging, etc. Packaging materials can be selected according to the type of items. Since fruit is a fresh food, it is still undergoing respiration, and a high degree of hypoxia will cause physiological diseases. Therefore, vacuum packaging is less used for fruit.

With the gradual improvement of people's living standards and the continuous improvement of the quality of life requirements, vacuum packaging has occupied an indispensable and pivotal position in contemporary people's lives.
