When we talk about how good retort pouches is, we are actually talk about its internal structural composition. It has the sturdiness of metal cans and protects the nutrient value of the food. Specifically, each retort pouch consists of four layers as shown in the image above:
1st layer (inner) – propylene which acts as a heat seal surface and provides strength and flexibility.
2nd layer – nylon layer protects from abrasion.
3rd layer – aluminum layer not only protects from lights, gases, and odor but also extends the product shelf life.
4th layer (outer) – polyester layer provides excellent strength and is very easy to print on.
The materials that we use to produce of retort pouches are FDA approved and undergo sterilization processes which increase the durability of the packaging.
