High temperature cooking bag is a kind of composite plastic film bag that can be heated, which has the advantages of canned container and boiling water plastic bag. Food can be sealed in the bag, after high temperature (generally in 120~135℃) sterilization heating, take out can be edible. It has the following advantages:
（1）The cost of nylon vacuum packaging bag is relatively low, compared with glass, paper, aluminum foil packaging. In order to achieve the same barrier effect, the nylon membrane has a great advantage in cost.
（2） Nylon vacuum packaging bag type, flexible material distribution design: the packaging industry often designs according to the bag products of different bag type and composite type, and the nylon vacuum packaging bag can be a good solution to this problem,
（3） High barrier resistance of nylon vacuum bag; high barrier effect on air and water.
（4）Nylon vacuum bag function diversity; nylon vacuum bag has oil resistance, moisture resistance, high temperature resistance of 120℃, low temperature freezing, quality protection, preservation, odor prevention and other properties.
