Advanced Vacuum & Retort Packaging Solutions
Engineered for high-temperature sterilization and long-term vacuum freshness. With 135°C extreme heat resistance and ultra-high barrier technology, Sengelin Packaging redefines packaging standards for ready meals and meat products.

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.
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.
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.
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.
