Compared with the rice brick bag, the type of vacuum bag is relatively much more, and its use is more extensive. For example, clothes, food, etc. can be packed in a vacuum bag. The vacuum bag mainly takes out the air in the packaging container and seals it, maintains the bag in a state of high decompression, and the air is rare, which is equivalent to the low-oxygen effect, so that the microorganisms have no living conditions, so as to achieve the purpose of fresh fruit and no disease rot. Applications include vacuum packaging in plastic bags, aluminum foil packaging, and glassware packaging. Packaging materials can be selected according to the type of item. Since the fruit is a fresh food, it is still undergoing respiration, and high oxygen deficiency can cause physiological diseases. Therefore, the fruit is less vacuum-packed. Its material can be roughly divided into four categories:
(1) wherein PE is suitable for low temperature use, RCPP is suitable for high temperature cooking;
(2) PA is to increase physical strength and puncture resistance;
(3) AL aluminum foil is to increase the barrier properties, shading;
(4) PET, which increases mechanical strength and is excellent in stiffness.
