The Complete Guide to Retort Pouch Packaging: Materials, Sterilization Standards, and QC
Retort pouch packaging is designed for heat, pressure, and long-term shelf stability. It acts as a "flexible can," saving logistics costs while maintaining food quality.
Manufacturer's Warning
A retort pouch MUST be engineered based on your specific sterilization temperature and pressure curve.
Material Structures: 121°C vs. 135°C
| Structure | Layers | Strength |
|---|---|---|
