High temperature retort bag (English name RetortPouch, referred to as RP) is a composite plastic film bag that can be heated. It has the advantages of both canned containers and boiling water resistant plastic bags. After more than ten years of use, it is a Ideal packaging container. The retort bags sold by Toyo Can Company in Japan contain aluminum foil called RP-F (resistant to 135 °C), and transparent multi-layer composite bags without aluminum foil are called RP-T and RR-N (resistant to 120 °C). European and American countries call this bag "soft can" (FlexibleCan or SoftCan).

The cooking bag is mostly made of three layers of heat-resistant materials. The typical structure of the cooking bag is: the outer layer is polyester film, which is used for reinforcement; the middle layer is aluminum foil, which is used to prevent light, moisture and air leakage; the inner layer is Polyolefin materials (such as polypropylene films) for heat sealing and food contact.
