Macro’s PLA Foam Extrusion Line is a tandem extruder system that produces expanded poly lactic acid sheet with 12:1 expansion ratio at output rates up to 400 kg/h.

Using advanced foaming technology, Macro's PLA line enables processors to foam biopolymer PLA - one of the most challenging resin to foam. A proprietary new extruder design is used to address obstacles that processors face when foaming PLA, namely working around the material’s low melt strength, melt crystallinity and narrow processing window. The result is uniform melt temperature distribution and reliable foaming.

The line is equipped with a sophisticated blowing agent injection system that ensures the right cell structure is created in the foam.
