Custom Retort Food Packaging Solutions

ICPG works with companies to select the ideal retort food packaging materials for their application.

Retort Packaging: How it Works

Retort packaging produced from rigid multi-layer plastic barrier structures offers an excellent alternative to cans or glass jars for shelf-stable applications. In the retort food packaging process, the food product is deposited into a barrier container, sealed, then processed in a multi-batch steam or water vessel, cooking the food product at a specified temperature over time in order to sterilize the food within the package.

Retort Food Packaging Applications

There are many advantages to using this method. Plastic rigid retort packaging materials are lightweight, durable and available in both clear and opaque structures. They are also customizable enabling branding opportunities such as utilizing post retort applicable printed shrink sleeves and lidding films. Common retort applications include packaging for products such as pet food, baby food, vegetables, and more. The sterilization process utilizing rigid barrier coextruded thermoformed containers ensures performance while providing extended shelf life protection.
