Vacuum & High-Temperature Retort Pouches
Engineered to withstand autoclave steam pressure sterilization at 121℃ to 135℃. Delivers 2-year ambient shelf life for ready-to-eat meals without refrigeration.
Engineered for High-Barrier Protection & Shelf Pop
Retort pouches are the technological successor to traditional metal tin cans and glass preserve jars. Engineered using advanced high-temperature barrier polymers, retort pouches withstand intense pressurized steam autoclaving at 121℃ (250℉) up to 135℃ (275℉) for 30 to 45 minutes, destroying all microorganisms inside the sealed pouch. At QINPACK, our retort pouches use multi-layer composite structures combining heat-stabilized PET, oriented Nylon (BOPA) for hydraulic puncture resistance, pure soft aluminum foil for absolute light and gas barrier, and medical/food-grade cast polypropylene (RCPP) for ultra-tough heat seal bonding. Ready-to-eat meals, curries, and pet wet foods maintain pristine flavor and nutrients at room temperature for 18 to 24 months without chemical preservatives.
