Green's the Theme in Extrusion and Compounding

摘要

Many extrusion and compounding machine builders are keeping their K 2019 plans under wraps,perhaps hoping to create a”wow”factor as attendees walk the halls in Diisseldorf next month.What follows is a rundown of new technology news gleaned by Plastics Technology though early August.Sustainability and the Circular Economy will be a prevalent theme throughout the show.In blown film,that will be reflected in technology to produce thinner films more consistently,sometimes using biobased materials such as PLA.Reifenhauser says film processors that upgrade lines with its EVO Ultra Flat Plus technology,an inline stretching unit integrated in the haul-off that was introduced at K 2016,can downgauge PLA films by as much as 30%.What's more,because with Ultra Flat Plus the film is stretched while it's still warm,the line can be run at speeds comparable to those of PE film production.This is significant because,according to Reifenhauser,PLA's inherent lack of stiffness generally slows production speeds.
