Light instead of glue – paper bonding with laser

Papierverpackungen punkten gegenüber Kunststoff: Sie lassen sich häufiger recyceln, verursachen oft weniger CO₂ und kosten meist weniger in der Entsorgung. Bisher erschweren jedoch dichte, sichere Verschlüsse den Umstieg. Häufig braucht es dafür Klebstoffe oder Kunststoffschichten. Wir zeigen und ihr probiert, wie Papierfügen auch ohne Klebstoff gelingt.

Description

Paper packaging has several advantages over plastic: it can be recycled more often, often generates less CO₂, and is usually cheaper to dispose of. However, until now, creating airtight, secure seals has made the switch difficult. This often requires adhesives or plastic layers. We’ll show you – and you can try it out – how paper can be joined without using any adhesive.
