Processing Methods

All processing methods outlined below act to extend food shelf life


Retort flexible packaging is a food processing method that uses steam or superheated water to heat product to temperatures typically in excess of 121°C or 135°C in a retort chamber. This sterilizes the product after food is packaged. Retorting is a technique that can achieve a shelf life of up to 12 months at ambient temperatures. Extra high barrier packaging is required for this process < 1 cc/m2/24 hrs.

Microwavable Retort Pouch contains a special ALOx polyester film, which has a comparable barrier property to that of the aluminum layer.
