What is vacuum packaging

Vacuum packaging is also called decompression packaging, which is to extract all the air in the packaging container and seal it to maintain a high degree of pressure reduction in the bag. The scarcity of air is equivalent to the effect of low oxygen, so that microorganisms have no living conditions to achieve freshness and no disease. The purpose of the occurrence. Applications include vacuum packaging in plastic bags, aluminum foil packaging, glassware, plastic and its composite packaging, etc. The packaging material can be selected according to the type of item. Since fruits are fresh and live food, they are still undergoing respiration, and high hypoxia can cause physiological diseases. Therefore, fewer fruits use vacuum packaging.

Features of vacuum packaging

  • Part of the air (oxygen) in the packaging container is eliminated, which can effectively prevent food from spoiling and spoiling.
  • The use of packaging materials with excellent barrier properties (air tightness) and strict sealing technology and requirements can effectively prevent the exchange of packaging contents, which can avoid food weight loss, loss of taste, and secondary pollution.
  • The gas inside the vacuum packaging container has been eliminated, which accelerates the heat transfer, which can improve the efficiency of heat sterilization, and also avoids the packaging container from rupturing due to gas expansion during heat sterilization.
