Explore the complete range of features built into our retort pouches. From advanced barrier protection to custom finishes, each element is designed to enhance performance, product life, and shelf impact.
Retort Pouch
Thin and lightweight pouches for ready meals to be heated in the microwave and are suitable for sterilisation.
The packaging of products like ready meals, sauces, soups, olives, chestnuts, and beets requires the ability to undergo sterilisation in pressurised tanks at temperatures of up to 131°C before being packaged. Retort flexible films and pre-made pouches emerge as the ideal packaging solutions for this product category.
Key Benefits of Retort Bags
In contrast to cans, they reduce retort time and offer convenience in terms of portability and usability. Our retort films and pouches can be crafted with two to four layers with recyclable options upon request.

Got questions about retort pouch packaging?
Here are some of the most common queries we get about our retort pouch packaging.
Products like cooked rice, pasta sauces, curries, soups, wet pet food, baby food, and ready-to-eat meals often use retort pouches for extended shelf life without refrigeration.
They undergo thermal processing in a pressure vessel (retort) where high temperature and pressure kill pathogens. This process allows the pouch to achieve similar food safety as canned products.
Typical structures include PET/ALU/CPP or high-barrier PET/EVOH/CPP laminates — designed to resist delamination, maintain seal integrity, and withstand retort conditions.
Retort pouches are designed for commercial sterilisation in pressurised retort chambers. Boilable pouches are typically for home use or low-temp pasteurisation, and cannot handle the same pressure or heat.
Retort pouches can offer a shelf life of 12–24 months without refrigeration, depending on the food type, barrier structure, and processing parameters.
Yes. We supply retort-compatible pouches suitable for form-fill-seal systems or pre-made pouch lines, designed with tolerances to handle high-heat conditions.
Absolutely. Proper headspace is essential to prevent over-expansion during the retort process. It also allows steam and heat to circulate evenly inside the pouch for thorough sterilisation.
Yes, vacuum sealing is required to remove oxygen before thermal processing. It helps minimise pouch expansion during the retort cycle and improves heat penetration for more efficient sterilisation.
Swelling can occur due to insufficient vacuum, overfilling, or incorrect headspace. Inadequate seal strength or poor lamination structure may also lead to pouch bursting under pressure and heat.
