The retort pouch is a composite plastic film pouch that can be heat treated. It 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 aluminum foil for light protection. For moisture and leak proof; the inner layer is a polyolefin film (such as polypropylene film) for heat sealing and contact with food. In terms of food packaging,
retort pouches have many unique advantages over frozen food pouches and metal cans:
Advantages and disadvantages of the retort pouch Do you make it?
1. Maintain the color, aroma, taste and shape of the food. The retort pouch is thinner and can be sterilized in a short period of time, and the original color, aroma, taste and shape of the food are preserved as much as possible.

Disadvantages of the cooking bag:
The retort pouch also has its shortcomings, mainly due to the lack of high-speed filling equipment, which has a certain impact on mass production.
