Adhesive-Free Paper Packaging Sealing: Where Laser and Heat-Bonding Processes Could Move Recyclability Forward, and Where They Can't Yet
Drawing on Fraunhofer’s PAPURE project and IOM3 reporting, this post organizes what laser-treating paper surfaces and bonding them under heat and pressure could mean for paper-packaging recyclability. It also walks through the paper conditions, seal strength, throughput, quality control, and pre-commercialization checks that have to be verified.
