Flexible Retort Pouch Food Packaging
A retort pouch built from AlOx PET, PA and RCPP that withstands sterilisation, protects flavour and shelf life, and suits ready meals, soups and sauces.
This is a retort pouch, a flexible pack designed for heat sterilisation after filling. The structure is AlOx PET / PA / RCPP. AlOx PET is a transparent oxide-coated polyester that provides an oxygen barrier without foil. PA (nylon) adds puncture and flex-crack resistance. RCPP is a cast polypropylene sealing layer that survives retort temperatures. The laminate is typically 100–120 microns, though exact thickness depends on the fill weight and process. It protects against oxygen, moisture and light while keeping the contents shelf-stable.
Retort pouches are used for ready meals, soups, stews, sauces and similar wet foods. They run on horizontal form-fill-seal or pouch filling lines, then go through a retort cycle. Sealing requires clean, flat seal bars and controlled pressure to avoid channel leaks. A tear notch helps opening; a spout suits pourable sauces but adds cost and needs a cap rated for retort. A window is possible only if the structure remains transparent, which AlOx PET allows. Choose a foil laminate when you need an absolute oxygen barrier for very long shelf life. A mono-material recyclable structure is lighter and more sustainable but may not match the retort performance and barrier of this AlOx PET / PA / RCPP build.

Frequently asked
Can this pouch be used for retort sterilisation?
Yes, the AlOx PET / PA / RCPP structure is designed for retort. It withstands typical sterilisation temperatures of 121°C for 30 minutes, depending on the exact laminate and fill weight. Always validate the process with your own retort cycle.
What is the minimum order quantity for custom printed retort pouches?
With digital printing, MOQ starts at 100 pouches. For rotogravure printing, MOQ is 10,000 pouches. Digital runs ship in 10–15 working days after artwork approval, while rotogravure takes 20–25 working days.
Does this pouch work on my filling line?
It is compatible with standard pouch filling and sealing equipment. The RCPP sealing layer needs clean, flat seal bars and controlled pressure. If you use a spout, confirm your filler can handle spouted pouches. Free stock samples are available so you can test before ordering.
