A Doypack is a sealed plastic bag that is designed to stand upright. Doypacks are commonly used for powders or ready-to-drink beverages. They can be aseptically filled or filled on normal packaging lines.

The Doypack was invented in 1962 as a packaging for fruit juice and olives, by the French inventor Louis Doyen, president of Thimonnier Company. The trademark “Doypack” (from DOYen PACKaging) is filed internationally and is owned by Louis Doyen.

Doypack is a sachet with a bottom fold and a particular outlay of stiffening weldsmikrodalgawhich create a modern and universal packaging. Its main advantages are: displaying the product in an upright position, a large surface for printing, a possibility of welding in a string closing or a topper, a price lower than that of alternative packaging systems.

Doypack packages are used for both manual and automated packaging of foodstuff (i.e. coffee, tea, spices, dried fruit, nuts, juice, mayonnaise, candy, etc.), seeds, chemicals, tobacco, etc. Doypack sachets are available in a variety of sizes, with or without a string closing, a topper, made out of materials of different colours, thickness and structure.
