What Is Retort Packaging?

Retort packaging is lighter than metal containers.

Food product packaging is constantly being improved and revamped to increase convenience, enhance storage options and lower shipping weights. Retort packaging combines several packaging options to augment all of these aspects.

Definition

The retort packaging process utilizes pressure and heat to cook and seal food in a container made of polymer plastic. Non-food retort packaging is commonly used for over-the-counter medicines.

Practical Advantages

Foods packaged in this manner are shelf stable, meaning they need no refrigeration to preserve them. The containers for food are often shaped like pouches or bowls that are microwaveable for convenience. Since there is no glass or metal in the packaging, items are lighter in weight and less expensive to ship. Retort packaged goods are also more convenient for consumers to take with them to work or school and generally less bulky, so they take up less space in cupboards.

Aesthetic Advantages

Retort packaging provides more space for verbiage and pictures on the containers than traditional package labels. Additionally, the lighter weight of the products provide retailers with more creative merchandising options throughout the store.
