What is a retort pouch?

times   2018-11-19

Retort pouch is a kind of composite plastic film bag which can be heated. It has the advantages of both canned container and boiling water resistant plastic bag. Therefore, it is also called "soft canned". After more than 10 years of use, it is proved to be an ideal packaging container for sale.

Retort pouches are made of three layers of materials. The typical structure of retort pouches is as follows: polyester film as the outer layer for strengthening; aluminum foil as the middle layer for light, moisture and air leakage protection; polyolefin film (such as polypropylene film) as the inner layer for thermal bonding and food contact.
