They are bags made with special and reinforced materials that in order to enter a recycling process, the laminations have to be maintained with materials from the same family of plastics (PE or PP), which allow them to enter a recycling process without having to to detach and separate the layers by type of plastic and likewise they can end up in the manufacture of another type of product with recycled materials. Sustainable packaging has evolved over the years, and new materials with higher barriers are being developed every time to provide a longer shelf life. At this time we find the possibility of manufacturing bags exclusively for dry products with sustainable materials in any type of bag, both with matte and gloss finishes. They can also be manufactured with a metallic layer that allows the products to have a longer shelf life.
