A retort pouch is designed to withstand high temperatures and pressures, making it ideal for preserving and sterilising food and beverages. Retort pouches are commonly used for packaging ready-to-eat meals, soups, sauces, and other shelf-stable products.

They are sealed using a process called retort sterilisation, which involves heating the pouches to high temperatures to kill bacteria and other pathogens, ensuring the safety and extended shelf life of the packaged goods.
