The difference between high temperature vacuum bags and frozen vacuum bags?

by：Kolysen 2021-01-27

High temperature vacuum bags and frozen vacuum packaging, are typical of polyolefin polymers. Two kinds of vacuum bags have many similarities, such as non-toxic, odourless, tasteless, health reliable performance; Acid, alkali, salt and a variety of chemicals, stable performance. Physical and mechanical properties of equilibrium; Well protected against dampness, moisture resistance, good, has the certain oxygen resistance, oil resistance; It has excellent formability and good heat sealing. And high temperature vacuum bag, high temperature vacuum bags also has the advantages of large quantity and wide source, low price. Compared to high temperature vacuum bags and frozen vacuum bags, the main difference is the following: 1, high temperature vacuum heat resistance is far better than the vacuum bags, frozen bags can be above 120 ℃ high temperature resistant, high temperature vacuum bag packaging food even able to withstand more than 140 ℃ high temperature cooking requirements. 2, high temperature vacuum bags transparency and strength is superior to frozen vacuum bags. High temperature vacuum bags oil resistance is not very ideal, but better than frozen vacuum bag. 3, and frozen vacuum plastic bags, compared the main disadvantage of high temperature vacuum packaging is the difference in cold tolerance, high temperature vacuum bag homopolymer in 0 ℃ or may show obvious brittleness. In summary: high temperature vacuum bags and frozen vacuum packaging difference is very big, see the product packaging requirements to determine what kind of vacuum packing bag suitable, is not the most expensive is the best, only suitable for product packing bag is the best.
