Taicang high-temperature cooking bag is a composite plastic film bag can be heat-treated, it has plastic containers and cans of both boiling water resistant advantages. Food can in the bag intact, high temperature (usually in 120 ~ 135 ℃) sterilization heating, remove and serve. After ten years of use it proved that it is an ideal sales packaging containers. For meat, soy products packaging, convenient, hygienic and practical, and can be good to keep the original flavor of the food, the more consumers. Taicang high temperature cooking bag structure in order to meet performance requirements retort pouch, its structure outer select high-strength polyester film, an intermediate layer of aluminum foil choose an opaque and air tightness, the inner layer of polypropylene film selection. There are three-layer structure: PET / AL / CPP, PPET / PA / have a PET / AL / PA / CPP CPP two kinds, four-layer structure. Retort pouch characteristics and requirements: 1, health: non-toxic, odorless, residual solvent measured value is less than 5mg / m2; no harmful component decomposition, precipitated by high temperature after cooking. 2, barrier: good gas barrier, moisture barrier, good mechanical strength. 3. Heat resistance: resistance to cooking resistance, high temperature resistance moment. 4, content resistance: resistance to media (sour, spicy, salt, alkali), excellent anti-oil properties, oil absorption rate of less than 1%. 5, Appearance: Good smooth, no wrinkles, bubbles and foreign attachment. 6, mechanical strength: good pressure resistance, high-temperature cooking requirements after the bag is not broken, do not change color, no distortion, separated layers.
