Retortable Tests for Retort Plastic Bags
Retort plastic bags (typically made from structures like PET/AL/NY/RCPP, PET/NY/RCPP, or PET/AL/RCPP) must undergo strict testing to ensure they can withstand high temperature, steam pressure, and long-term food storage. The following tests verify bag performance, safety, and durability.
Temperature: 115°C – 135°C (commonly 121°C or 125°C)
Duration: 20–45 minutes
Bag is placed in a retort autoclave under steam + pressure.
Checks for:
- Lamination stability
- No delamination
- No leakage
- No deformation
- Seal integrity maintained after heating and cooling
Burst & Pressure Resistance Tests
Burst & Pressure Resistance Tests
Bag is filled and pressurized until it fails.
