1. How does sustainability affect plastic extrusion machine purchasing decisions?
Increasing recycled content requirements alter machine specification. Extruders need screws designed for high contamination and viscosity fluctuation, plus filters and degassing. Europe's Packaging and Packaging Waste Regulation sets recycled content targets for plastic packaging, pushing processors to retrofit older lines rather than buy virgin-only equipment. Single-screw machines with larger L/D ratios and side-feeding units are becoming the default for post-consumer resin processing.
