Key Considerations for Designing a Retort System for Shelf-Stable Food Packaged in Flexible and Semi-Rigid Containers
Consumers today increasingly prefer flexible and semi-rigid packaging as compared to rigid materials in a growing number of human and pet food products. Consumers perceive pouches, bowls and trays as new and innovative, space saving, convenient and more sustainable through less waste. New microwaveable packaging is a big part of the convenience factor. Not only do flexible and semi-rigid materials help to boost sales, but this packaging also lowers unit cost and can reduce sterilization time by up to 50%.
Making the switch from rigid containers such as steel cans and glass jars and bottles is not as simple as substituting one material for another. Flexible and semi-rigid packaging does not fill, seal, handle or perform in a retort like cans or jars. Basically, a new line is required.
