Returning high-barrier film back into the circular economy has been considered almost impossible. Together with partners, however, W&H has developed a film concept that allows the multilayer barrier film made from different types of plastic to be dissolved. The separation of the polymer layers is made possible by water-soluble layers within the structure. The result is pure plastics that can be regranulated and recycled individually as a product. The VAREX II blown film line provides the optimum melt distribution necessary for the production of the recycled film.
