Thermal Autoclave Resistance. Can-Replacing Flexible Barrier.
High-temperature autoclave-sterilizable barrier pouches for shelf-stable ready-to-eat meals and soups.
Retort pouches are heat-resistant pouches made from laminates such as PET, aluminum foil, nylon and CPP that survive sterilization after filling. Sealed food can then sit on a shelf without refrigeration, so retort pouches replace cans and jars for ready meals, curries, soups, seafood and wet pet food.
Also called: retortable pouches, sterilizable pouches, autoclave pouches, MRE pouches, high-temperature food pouches, shelf-stable pouches.
Custom Retort Pouches are thermal-processing flexible food pouches engineered to withstand high-temperature autoclave sterilization (up to 121°C / 250°F). Made from multi-layer laminates of PET, Aluminum Foil, Nylon, and CPP, these durable pouches replace metal cans and glass jars for ready-to-eat meals, curries, soups, seafood, and wet pet food, offering a shelf-stable shelf life without refrigeration.
Custom Retort Pouches represent a major technological leap in preserved food packaging, replacing traditional metal tin cans and glass jars with lightweight, flexible laminates. Engineered to endure commercial autoclave retort processing (high-pressure steam heating up to 121°C / 250°F for 30–50 minutes), retort pouches sterilize cooked food inside the package, giving ready-to-eat meals a multi-year shelf-stable shelf life without chemical preservatives or refrigeration.
Constructed using a specialized 4-ply laminate structure (PET for print clarity, BOPA Nylon for puncture resistance, Aluminum Foil for zero oxygen/light transmission, and Retort-grade Cast Polypropylene for high-temperature sealing), retort pouches heat faster than tin cans during cooking. This reduces thermal stress on food, preserving natural flavors, textures, and nutrients while reducing shipping weight by up to 75%.

Retort pouches are almost always ordered in bulk by food manufacturers and co-packers running sterilization lines. For a wholesale quote, tell us the fill weight, the retort temperature and time you run, and whether you need a tear notch or a spout, and we quote the laminate to match.
Yes. Cubit makes retort pouches to order in its own factory and quotes them factory-direct, so wholesale buyers deal with the manufacturer, not a reseller. Send your size, quantity and artwork, and we price your exact specification.
Price is per bag and depends on size, film, print colors, closures and quantity. The bigger the run, the lower the price per bag, because setup is spread over more bags. List several run sizes in your request, for example 5,000, 10,000 and 25,000, and we quote each one.
Yes. Large runs are where our factory is most efficient, and we quote orders of 100,000 bags and more. Tell us in your request if you need the order delivered in stages or repeated on a schedule.
