A stand-up pouch or doypack is a type of flexible packaging that is able to stand erect on its bottom for display, storage, and convenience.[1] It has characteristics of plastic bags, water bottles, and retort pouches. The bottom part of a stand-up pouch is gusseted to provide support for display or use.[2]
Stand-up pouches are commonly used for food packaging. They can be aseptically filled or filled on normal packaging lines.[3]
