High temperature cooking bag is a kind of compound plastic film bag which can be heated. It has the advantages of can container boiling water resistant plastic bag, so it is also called "soft can". After more than ten years of use, it has proved to be an ideal sales packaging container.
High temperature cooking bag is composed of three layers of materials. The typical structure of cooking bag is: the outer layer is polyester film for strengthening; the middle layer is aluminum foil for light proof, moisture proof air leakage proof; the inner layer is polyolefin film (such as polypropylene film) for heat sealing contact with food.
