Barrier Shrink Packaging Currently Used Includes Barrier Shrink Packaging Bags

Low-temperature Barrier Shrink Packaging is also called decompression and low-temperature Barrier Shrink Packaging, which extracts all the air in the packaging bag and seals the Barrier Shrink Packaging to make the Barrier Shrink Packaging in a high vacuum state. The scarcity of air is equivalent to a vacuum effect, so that microorganisms are not Breeding and living conditions to achieve fresh fruit without corruption. One of the steps is deoxygenation, which helps prevent food from spoiling. The principle is also relatively simple. The mildew and spoilage of food is mainly caused by the activities of microorganisms, and most microorganisms (such as molds and yeasts) need oxygen for their survival, while low temperature Barrier Shrink Packaging uses this principle to extract the oxygen in the packaging bag and food cells, so that the microorganisms lose the \"survival environment\". It does not deteriorate and reduces the loss of vitamin A and C.

Barrier Shrink Packaging currently used includes Barrier Shrink Packaging bags, aluminum foil packaging bags and glassware packaging. The packaging material can be selected according to the type of item. Because fruits are fresh and live food, they are still undergoing respiration, and high hypoxia can cause physiological diseases. Therefore, Barrier Shrink Packaging is rarely used in fruits.
