Polylactic Acid (PLA) Foam Extrusion Line

Renewable, Compostable Alternative to PS Foam
 

 

 

Macro’s PLA Foam Extrusion Line is a tandem extruder system that produces expanded poly lactic acid sheet with 16:1 expansion ratio at output rates up to 300 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.

Along with the line, Macro provides the know-how to operate it; Macro supplies the complete PLA recipe and processing conditions along with process training, and stands behind the machinery with industry-leading after sales support.

As with all Macro machinery, the line is constructed using the latest technology, highest quality materials and superior workmanship.

Macro is actively developing new technologies for use with this extrusion line to expand the application range of foamed PLA.
