Packaging Technology for Harsh Processing Conditions

Sengelin Packaging uses professional material structures and process parameters to help vacuum and retort packaging withstand high temperature, high pressure, oxygen exposure, and long-term shelf-life requirements.

01 / Retort Resistance

High-Temperature Sterilization

Our retort pouches support 121°C to 135°C high-temperature and high-pressure sterilization. A dedicated RCPP inner layer helps prevent delamination, cracking, and harmful substance migration during thermal processing.

121°C–135°C RCPP Inner Layer No Delamination
02 / Vacuum Barrier

Ultra-High Vacuum Barrier

For meat products and ready meals that require long-term ambient storage, PA nylon and AL aluminum foil multi-layer structures provide near-zero oxygen transmission, helping prevent fat oxidation and microbial growth.

PA Nylon AL Foil Barrier Oxygen Control
03 / Shelf-Life Protection

Flavor & Nutrition Retention

Excellent seal integrity helps food maintain its original taste and nutritional quality after sterilization. The pouch structure reduces leakage, moisture loss, and oxidation to extend shelf life to 12–24 months.

12–24 Months No Leakage Flavor Lock
