Doypack bags: innovative packaging for your products

In the world of packaging, the Doypack pouch has established itself as a modern, versatile solution. Designed to meet the varied needs of the food, cosmetics and chemical industries, this packaging offers attractive presentation and optimum product preservation. In this article, we explore the features of Doypack pouches, their benefits and the types of products they can contain.

What is a Doypack sachet?

The Doypack is a flexible packaging with a stable base that allows it to stand upright on shelves, improving its visibility. Invented in 1963, it is generally made up of several layers of materials such as paper, polyethylene and aluminium, providing an effective barrier against moisture, oxygen and external contaminants. This design ensures optimum protection for products, whether solid or liquid.
