Cooking bags full analysis, not to be missed!

Cooking bags, commonly known as & other; Soft canned & throughout; , commonly used in food packaging, at room temperature preservation, shelf life of more than 6 months, and requires good barrier property, penetration resistance, and do not break in cooking environment properties, such as, no contraction, no smell. 1. Cooking bags of PET/AL/RCPP common structures ( PE） PET / PA / AL / RCPP ( PE） PET / AL / PA / RCPP ( PE） PA / AL / RCPPPA / RCPP ( PE） PET / RCPP ( PE） PA / PA / RCPPPET / PA / RCPP ( PE） 2. Cooking bags for barrier property: good resistance, resistance to wet gas, good mechanical strength. Safety and health, non-toxic, no smell, determination of residual solvents value is less than 5 mg/m2; After high temperature cooking without harmful ingredients decomposition and precipitation. The contents resistance: resistance to medium ( Sour, hot, salt, alkali) , good oil resistance and oil absorption rate & le; 1%. Heat: during cooking, instant high temperature resistance. Good mechanical strength, compression resistance, asked not broken after high temperature cooking bags, discoloration, deformation, no delamination. Good appearance: smooth and no fold, bubble and foreign body attached. 3. Cooking packaging sterilization temperature low temperature cooking bags, 105 ℃ for 30 minutes sterilization) Medium temperature cooking bags, 121 ℃ for 40 minutes (sterilization) High temperature cooking bags, 135 ℃ for 20 ~ 30 minutes) sterilization Ultra high temperature sterilization bags ( 145 - 150 ℃, a few seconds to a few minutes the sterilization) 4. Cooking transparent class should choose on the choice of packaging material and structure of PET, PA, CPP, PE structure; Opaque class should choose to contain AL material composition structure; On the bag size and the thickness of lining material and how much content, and shall ensure that the bearing strength, when select material should emphasize the packing for retort pouch, major indicators have corona strength, tear strength, tensile strength, temperature tolerance, surface cleanliness, less additives after cooking is not easy to precipitate, extraordinary good heat sealing of lining materials. Cooking bags each material selection requirements are as follows: AL: hot-rolled wool, pinhole, cleanliness, 1% elongation, tensile strength of 65 n/was and corona strength and thickness of choice. PA: to understand the forming method, mainly by stretching, synchronization, stretching and tube membrane forming, uniform thickness and anisotropy abnormity good should be the membrane of the synchronous stretch forming, and used for cooking and packaging will be only a small part of the room, it necessary to choose double corona, used in the middle tier and packing is good, because the PA easy absorption of moisture. Ink, glue and the choice of solvents cooking conditions to choose to suit the corresponding ink and glue, and get the production validation. Purity of solvent ethyl ester is crucial, want is required ( Water cut less than 0. 1%, alcohol is less than 0. Not more than 0 1%, free acid. 004%) 。 5. In the production of cooking bags should be equipped with testing instruments with back pressure adjustable temperature and pressure cooker tensile sample instrument measuring the gluing quantity with the analysis of the balance gas chromatograph water pressure test gauge meter halo pen or the processing of the mixed fluid is 6. Cooking bags production as far as possible choose fewer printing design, best left blank heat sealing side. To understand the cooking bags of food enterprise production conditions, should strictly control the temperature when told they use within the range of retort pouch production enterprise guarantee, because even beyond a few degrees, due to various kinds of materials have reached are often limit, the performance of the retort pouch can guarantee is critical. Food enterprises should make use of batch cooking bags before cooking bags, confirmed that the performance of this kind of release in the specific process under the condition of retort pouch could use the technology conditions of verification, because the packaging of the physical and chemical properties, as well as at high temperature because of the physical and chemical changes may occur and produce new substances such as are possible in the retort pouch layer infiltration causing retort pouch packaging performance degradation, such as to cause to take off the floor, even if is the vacuum degree within the retort pouch can also cause retort pouch stress differences between layers, leading to poor fastness of film layer between layers. Retort pouch production to strengthen production management work, completes the technical index of each process detection and control, in particular to hold good cooking cooking bags before they leave the factory test finally. To check before feeding film corona treatment whether meet the requirements, it is very important to print fastness and composite fastness. Ensures that the curing time, let the two-component ink and glue fully crosslinking curing reaction.
