A retort pouch is a type of food packaging made from a laminate of flexible plastic and metal foils.It allows the sterile packaging of a wide variety of food and drink handled by aseptic processing, and is used as an alternative to traditional industrial canning methods.his multi-layer structure prevents the retort pouch from being recycled into other retort pouches or food packaging.

Such a situation can result in a very few cans of underprocessed product in a large lot of containers. After the product has been processed cooling water is normally brought into the retort to partially cool the product. In some systems the product is dumped from the bottom of the retort into a cooling canal. The discharge door on some systems is below the level of the water in the cooling canal. This causes a vacuum to be formed in the retort and the cans are supposed to drift slowly out of the retort into the cooling canal.
