A new production line for cast polypropylene (CPP) film has been introduced by German equipment maker Reifenhäuser can produce high quality, transparent film in seven-layer structures at output rates of 300 m/min. The unit, MIDEX 7-150/90/80/4x60-2500, consists of seven extruders (150-, 90-, 80-, and four 60-mm units), a seven-layer feed block, as well as a company-developed flat die (BSD-CR04-2400) with thermobolts. It includes encapsulation on the sides to reduce scrap production and promotes edge trim recycling which can be feed back into one of the extruders for optimal processing at lower costs. Throughput is up to 1000 kg/hr, the film width is 2000 mm, and web thickness can vary from 0.012-0.250 mm. The unit targets PP markets such as barrier packaging, metalized PP films, lamination web produced in either PP or polyethylene, as well as stretch film. The unit allows remote diagnostics via the companys VPN (virtual private network) system conducted through the Internet to help prevent downtime of a processor's line.
