A retort pouch is a sterilizable flexible pouch constructed of a thin, bonded film that can withstand processing a product inside at 250°F (120°C) for a minimum of 50 – 55 minutes. It is probably most familiar to the public for tuna fish in a pouch, one of the industry’s earlier adopters.

Why is the Retort Pouch Revolutionary?
Many consumers may not be aware that the product within a retort pouch is cooked right in the sealed pouch. This revolutionary packaging process is called retorting and is the same process as autoclaving, which is the ability to heat and sterilize the packaging and contents. Both these heating and sterilization methods are used in the food and non-food manufacturing industry to commercially sterilize instruments or packaging and components, or cook product after it has been placed into its package. The retort pouch is filled with the product to be heated, is then hermetically sealed (airtight), and processed according to industry guidelines for time and temperature. Usually, this is a minimum of 50 minutes at 250°F
The construction of layering various types of plastics and thin metal foils takes the place of traditional cylindrical metal cans or glass jars, and the flexible retort pouches are then processed in a heated pressure vessel.
Retort food canning removes all the air from the container. Commercially, this is done by filling a large chamber with steam and then cooling the steam, creating a vacuum. Chamber vacuum sealers are an alternate way of creating the vacuum, though they do not heat the contents. The commercial version of the retort process also cooks the food in the pouches at the same time; home process will see the food cooked in a pressure cooker instead, much as if you were doing regular canning, except with the vacuumed pouch instead of a mason jar. Read more for regulatory and safety information on acidified foods and low-acid hermetically sealed foods.
The key to retort pouch production is excellent and high-quality lamination. IMPAK understands the technology and methodology required to bond the layers of a retort pouch together with a secure seal and a polished look.
Our machines can produce retortable and autoclavable flexible packaging from small sizes to larger options. Retort pouches can include other design considerations such as having tooling available to create a dispenser tip, 55-gallon drum liners with integrated round bottoms, stand up pouches, and other custom shapes and fitments. The layers of plastic and thin foils create a barrier impervious to gases and moisture entering or exiting the packaging.
IMPAK can customize the retort pouch design using the raw materials in various sizes or shapes. We can produce retortable pouches, from 1” x 3” to 30” x 68” and more. Call now for more information about your product requirements.

How is retorting and asceptic processing different than traditional industrial canning methods?
Retorting differs from traditional canning methods using metal cans or glass jars as it takes considerably less time to heat the contents to temperature. Retort pouches allow more surface area and even distribution of heat, rather than waiting for the contents to heat from the outside walls to the center through a cylinder.
Retorting technology’s goal is to produce ambient-temperature, shelf-stable, high-water activity, low-acid foods with higher quality than traditionally canned contents.

IMPAK produces custom printed pouches and packaging with an emphasis on materials with distinctive barrier properties to protect products from the adverse effects of moisture, oxygen, light and more. Learn about our unique custom capabilities.
High barrier bags are used to preserve and protect products. When paired with an oxygen absorber or desiccant, products enjoy even greater shelf-life and stability. However, selecting the appropriate package is not always as straight forward as it seems.
Not every Industrial Vacuum Sealer applies to every application. There are different models and types of Vacuum Sealers available, and each one of those sealers has different features that can affect the way a production line works.
