A laser-based process that enables adhesive-free paper packaging
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…
