EXTRUSION PERFORATION SYSTEM AND METHOD

An extrusion system includes a system to pump a thermoplastic resin melt through an extrusion die, the thermoplastic resin including a polymer base whose rheological properties are modified using fillers, a perforation/embossed roll, and a resilient/pressure backing nip roll through which the extrud...

Zusammenfassung:	An extrusion system includes a system to pump a thermoplastic resin melt through an extrusion die, the thermoplastic resin including a polymer base whose rheological properties are modified using fillers, a perforation/embossed roll, and a resilient/pressure backing nip roll through which the extruded thermoplastic resin melt travels between the perforation/embossed roll and the resilient/pressure backing nip roll in a roll nip/station area, exiting the roll nip/station area and around the resilient/pressure backing nip roll and subsequently released from the resilient/pressure backing nip roll as a perforated film, film or fabric carrier supported perforated film, coex laminate, or cut into sheet
