Paper reel downstream of the sealing module. The cutouts for the four-sided bags are clearly visible.
Paper packaging offers a number of advantages over its plastic counterparts: It has a high recycling rate, lower CO₂ emissions, and lower disposal costs. However, it cannot yet be sealed without adhesives or layers of plastic—a disadvantage for manufacturing and recycling processes. In the PAPURE project, four Fraunhofer institutes are developing a laser-based process that enables completely adhesive-free paper packaging.
