Retort Autoclave Pouches
Engineered to withstand extreme autoclave steam sterilization (121℃–135℃) while providing 24-month ambient shelf life without refrigeration.
Engineered for High-Barrier Protection & Shelf Pop
The Retort Pouch is a flexible laminate container capable of withstanding the thermal processing pressure and temperatures (121°C to 135°C / 250°F to 275°F) required for commercial sterilization of food products. Often termed flexible tin cans, retort pouches deliver 18 to 24 months of shelf stability at room temperature without preservatives. QINPACK produces both foil-based ultra-barrier retort pouches and microwaveable transparent barrier pouches using specialized cast polypropylene (R-CPP) sealant films that maintain seal strength throughout 45-minute autoclave cycles.
