Hot/Cold-Needle Perforation

Description

In this process, conical needles pierce the web (e.g., paper, thin metal foils, PE films). The grooves of the counter roller match exactly with the needle pattern. The needles create funnel-shaped holes. This causes, for example, in paper increased water permeability and in PE films air permeability.
