- A critical defect.
A leaker is a retort pouch that is unsealed or in some way has lost container integrity. Contents generally seep from the pouch. The leak may occur anywhere on the pouch.
- The pouch was punctured or cut during processing, handling or distribution.
- The sealing bar settings were not correct (i.e., the temperature, pressure and/or dwell time).
- The seal area was contaminated with product, moisture, grease, or other contaminants.
- The corner folded during the sealing operation, resulting in non-fusion at the corner.
