Retort pouch built from AlOx PET, PA and RCPP for heat sterilisation up to 135°C, giving a high barrier to oxygen and moisture for ready meals and sauces.
This retort pouch is a flexible pack designed for in-pack sterilisation. The structure is a three-layer laminate: an AlOx PET outer layer, a PA middle layer and an RCPP food-contact sealant. AlOx PET provides an oxygen and moisture barrier without aluminium foil, so the pack can be metal-detected and microwave-reheated. PA adds puncture and flex-crack resistance through the retort cycle, while RCPP gives a seal that holds at 135°C. Thickness is set by the application; the sealant layer must be thick enough to survive the fill and retort process without channeling.
The format suits foods, soups, stews and sauces that are filled hot or cold and then retorted. Fill through the open top, then seal and trim. A spout and cap can be added for squeezable or pourable products, and a tear notch helps opening. A zipper is not recommended for retort because the track can deform under heat. If you need a fully recyclable structure, a mono-PE laminate will not match the 135°C barrier of AlOx PET/PA/RCPP; it is better for pasteurised or chilled products. Choose this retort structure when shelf stability and heat resistance are the priority.
