Stand-up pouch, also known as doypack, is a type of flexible packaging which is able to stand erect on its bottom for display, storage, and use. It is a type of bag but sometimes also has bottle characteristics. Doypacks are commonly used for powders or ready to drink beverages. The bottom part of a stand-up pouch is gusseted to provide support for display or use.
The packaging machinery involved typically forms the pouch from preprinted roll stock. The preformed pouches are shipped to a packager where they are filled and the top is sealed.
The alternative is an integral form-fill-seal machine, whether vertical or horizontal. The equipment forms the pouches, fills the pouches in-line, and seals them. With foods, drinks, or medical products, special sanitizing and wash-down requirements are critical.
