It is widely used for packaging ready-to-eat meals, sauces, pet food, and liquid foods, offering a lightweight and durable alternative to traditional cans and jars.
In simple terms:
A retort pouch is used to safely preserve food while maintaining taste, texture, and nutritional value over long periods.
Retort pouches are made from multi-layer laminated materials, typically including:
Polyester (PET) – heat resistance
Aluminum foil (AL) – barrier protection
Nylon (PA) – puncture resistance
Polypropylene (CPP) – sealing layer
After filling, the pouch undergoes retort sterilization (usually at 121°C / 250°F), which eliminates bacteria and extends shelf life.
