June 11-12, 2024 The Polymers Center, Charlotte, NC
It’s a workshop, not a conference!
Learn how to compound and process a wide range of bioplastic formulations. Space is limited, we suggest you register ASAP. Previous workshops have sold out.
Leistritz Extrusion will host the 2nd Annual Bioplastics Twin Screw Extrusion Workshop June 11-12, 2024 at The Polymers Center in Charlotte, NC. A unique facet of this program is that classroom sessions are supplemented by interactive “hands-on” extrusion demonstrations, as well as screw assembly, equipment cleaning and maintenance procedures.
