Identification 

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.

Causes

  2. The sealing bar settings were not correct (i.e., the temperature, pressure and/or dwell time).
  3. The seal area was contaminated with product, moisture, grease, or other contaminants.
  4. The corner folded during the sealing operation, resulting in non-fusion at the corner.
