A new manufacturing process uses lasers to seal paper packaging instead of glue
SMRTR summary
German researchers developed a laser-based sealing process that uses carbon monoxide lasers to seal paper packaging without glue or plastic adhesives, making recycling easier and more effective. The technology heats paper surfaces to create natural bonding compounds from lignin and cellulose, producing seals strong enough to support 44-pound loads while eliminating contaminating additives.
