The retort pouch is a composite plastic film pouch that can be heat treated. It has the characteristics of both a canned container and a boiling water resistant plastic bag. Therefore, it is also called a "soft can".
The retort pouch is made up of three layers of materials. The typical retort pouch structure is: the outer layer is a polyester film for reinforcement; the middle layer is the aluminum foil for light, moisture and leak proof; the inner layer is polyolefin Membrane (such as polypropylene film) for heat sealing and contact with food.
High-temperature cooking bags are usually stored at room temperature, requiring a long shelf life, and the shelf life is generally more than one year, so there is a high requirement for the composite quality of the package:
(1) The appearance is flat, no wrinkles, bubbles and foreign matter adhere.
(2) Non-toxic, odorless, residual solvent measured value is less than 5mg/m2.
(3) Completely sealed, the water vapor transmission rate is close to zero, and is not more than 0.5g/m2·24h for the three-layer and four-layer structures.
(4) It has light-shielding properties and no gas permeability. The PET/CPP ordinary bag is required to be slightly lower, the oxygen permeation amount is not more than 3000px3/m2·24h·atm, and the three-layer and four-layer structure is 12.5px3/m2·24h·atm.
(5) No leakage, excellent anti-grease performance, and oil absorption rate is not more than 1%.
(6) Excellent heat resistance and pressure resistance. After high temperature cooking at 121 ° C for 40 minutes, no deformation or peeling is required.
Weight or Capacity depends on bag's content sizes. Please consult us or request a sample to ensure the packaging fit to you.
