During retort processing, pouches are exposed to 121–135°C under pressure.
The packaging must maintain its seal integrity, barrier performance and structural stability throughout this process.
A pouch that looks perfect before retort may delaminate, develop pinholes or lose barrier properties after retort — and that failure only becomes visible months later on the retail shelf.
