Retort Packaging

Retort is a cooking process that uses heat and pressure to cook food in its sealed package. Retort conditions are quite demanding with temperatures typically ranging from 251°F to 270°F. Capran® biaxially-oriented nylon film provide the strength, toughness, puncture and burst resistance that enable flexible pouches to withstand the strenuous retort process, shelf life requirements and demanding shipping and handling distribution.

Common flexible retort pouch structures utilizing Capran® biaxially-oriented nylon film include the following :

PET / FOIL / C1500 or 1500RT / CPP
PET / C1500M or 1500RT / FOIL / CPP
PET-SiOX or AlOX / C1500 / CPP

Due to their thinner dimensions, it takes less time to cook food in a flexible pouch than in other forms of rigid packaging such as cans and jars. This reduced retort time results in foods that have superior taste. Flexible retort pouches offer a variety of additional benefits over rigid packaging to both retailers and consumers that include :

Superior taste due to reduced retort time
Extended shelf life
Reduced storage space, both in warehouse and pantries
Reduced transportation costs
Easier and safer tear-open/disposal consumer experience
Microwave convenience
