Decoseam™

What is it?

Decoseam™ is Aisa’s unique side-seam welding technology. For the first time, this technology allows the properties of the outer web layer to be changed independently from the inner web layer. In fact, because the outer layer is no longer welded onto the inner layer (overlap), we can now optimise for sustainability, security, touch, decoration or any other value-added functionality that customers desire.

1. Decoseam™ strip is fed into the centre of the butt-weld seam, while the flat decorated laminate is formed into an endless tube!
