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.
Recommended Production Options:
Autoclave 121℃~135℃ Retort Cycle & Barrier Integrity
Medical and culinary retort packaging designed to survive pressurized steam sterilization with zero delamination.
Supports 135°C ultra-high temperature rapid sterilization without blistering.
Compensates internal pouch steam expansion to prevent seal burst during cooling.
Cast polypropylene (RCPP) inner layer resists sharp bone and shell puncture.
Odorless aliphatic adhesive eliminates solvent migration into processed meats.

Why Brands Specify This Pouch Format
Replaces Heavy Metal Cans
Saves up to 90% packaging weight and eliminates sharp tin can lids and metal taste leaching.
Withstands 121℃ to 135℃ Autoclaving
Specialized cast polypropylene (RCPP) maintains seal tensile strength (>40 N/15mm) through thermal processing.
Faster Thermal Cook Times
The slim profile allows heat to reach the center of the food 50% faster than round cans, preserving texture and nutrients.
Absolute Zero Gas Transmission (OTR/WVTR)
Pure aluminum foil layer prevents oxidation, color degradation, and rancidity for up to 3 years.
Microwaveable Retort Options
Available in non-foil transparent barrier structures (PET/BOPA/SiOx/RCPP) safe for consumer microwave reheating.
100% Hermetic Seal Assurance
Each lot is subjected to burst pressure inflation tests and ASTM bubble vacuum leak tests.
