Product information

AQUAREX - Water-quench blown film line - extrusion turned up-side-down

AQUAREX turns blown film production upside down and changes the typical structure of a blown film line. It extrudes downwards and uses water instead of air as cooling medium. The use of water allows extremely fast cooling of the melt, a low degree of crystallization and an extremely amorphous film structure. The result is a film with a striking gloss, high transparency and exceptional puncture and tear resistance.

These properties could formerly only be achieved by PVC extrusion or - to a limited degree - on cast film lines. AQUAREX thus opens up completely new applications for PE materials in the packaging sector and scores with its user-friendly handling.
