Aluminum Foil Bags Retort Pouch is a kind of composite plastic film bag that can be heated, which has the advantages of canned containers and boiling water resistant plastic bags, so it is also called "soft cans". After more than ten years of use, it has proved to be an ideal sales packaging container. The cooking bag is composed of three layers of materials, and the typical structure of the cooking bag is: the outer layer is polyester film for strengthening; The middle layer is aluminum foil, which is used for anti-light, anti-moisture and anti-leakage; The inner layer is a polyolefin film (such as polypropylene film) for thermal bonding and food contact.
