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
An extrusion system comprising:
The system of 2 wherein the perforation/embossed roll and the resilient/pressure backing nip roll include internal circulation of a heat transfer medium.
The system of 3 wherein the perforation/embossed roll is a metal roll such as a steel core roll or equivalent whose surface has been engraved to contain three-dimensional designs.
The system of 4 wherein the resilient/pressure backing nip roll is a hard durometer rubber roll.
The system of 5 wherein the resilient/pressure backing nip roll is encased in polytetrafluoroethylene (PTFE) shrink-wrap or similar fluoropolymer film to enhance roll durability, durometer, and release of cooled polymer film and chads.
A system comprising:
A method comprising:
