☆☆☆ ☆☆☆ ▲ Vacuum Packing definition ▲: also known as decompression packaging, packaging container is air sealed inside all out to maintain the bag in a high vacuum condition, scarce air hypoxia equivalent effect, no microbial living conditions, so as to protect the effectiveness of the product. ▲ mechanism ▲: to reduce the oxygen content of the package to prevent the deterioration of packaged food mold rot 2, vacuum packaging relative to the normal method of packaging, it reduces the space occupied by the article and has anti-bacterial moisture and dust, etc., to make. more convenient transportation and clothing items. 3, greatly reducing losses caused some unexpected possibilities. Features ▲ ▲ :. exclude packaging container portion of the air (oxygen), can effectively prevent rust food spoilage and precision mechanical parts. 2, using barrier (tightness) excellent packaging materials and sealing technology and strict requirements, can effectively prevent the exchange package contents substances to avoid food weight loss, loss of taste, but also to prevent secondary pollution. 3, the gas inside the vacuum packaging container has been ruled out, accelerates the heat conduction, which can improve the thermal efficiency of sterilization, but also to avoid the heating sterilization because of expansion of the gas leaving the containers rupture
