What MuCell Extrusion does

MuCell Extrusion LLC is a Boston-area (Leominster, MA) technology company that develops and licenses microcellular extrusion technology for the plastics packaging industry. Its core innovation is the injection of inert atmospheric gases—nitrogen (N₂) or carbon dioxide (CO₂)—in a supercritical fluid (SCF) state into polymer melts during sheet and film extrusion, producing a foamed cellular core encapsulated within solid polymer skins that performs equivalently to solid plastic while using substantially less material.

The company's product portfolio centers on three core components—the MuCell SCF Unit, Interface Kit, and MTM (MuCell Transfer Mixer) barrel extension—that together retrofit standard extrusion lines into microcellular extrusion lines. Supporting equipment includes the high-capacity Series K and compact Series S SCF delivery systems, Booster Box, Satellite Controller, Temperature Controller, Line Pressure Controller, Splitter, proprietary sheet and film dies optimized for foaming, and true gauge control systems. The technology is compatible with LDPE, LLDPE, HDPE, PS, PP, PA, PVDF, PET, PLA, PVC, and TPE, and is deployed across sheet extrusion (form-fill-seal, thermoforming, HDFT, signs/displays, construction, gaskets/seals) and film extrusion (lamination films, stand-up pouches, collation shrink, agriculture, pet food bags, surface protection). End products include pouches, sachets, trays, pots, and containers used in volume consumer packaging.

MuCell Extrusion operates on a turnkey licensing-plus-equipment model, in which each customer engagement includes a one-off fee for application-specific intellectual property plus equipment and installation, with technicians embedded in customer new product development workflows. The company maintains a lean staff of 1-10 employees and development facilities in both the USA and Europe. It is a wholly-owned subsidiary of Zotefoams plc, a UK-listed polymer materials technology group, and sells exclusively to enterprise consumer packaging manufacturers through a direct field sales motion.

Core offering

MuCell Extrusion develops, licenses and sells a patented microcellular foaming technology for sheet and film extrusion lines. The company injects inert nitrogen (N2) or carbon dioxide (CO2) in a Super Critical Fluid (SCF) state into polymer melts, creating a foamed core within a solid skin that uses 15-20% less polymer while maintaining solid plastic performance. It sells turnkey equipment packages (SCF units, interface kits, MTM barrel extensions, proprietary dies, gauge control systems) plus application-specific intellectual property to consumer packaging manufacturers.

Product overview

MuCell Extrusion offers a comprehensive portfolio of polymer reduction technology equipment centered on its patented microcellular foaming process. The core system comprises the MuCell SCF (Super Critical Fluid) Unit, Interface Kit, and MTM (MuCell Transfer Mixer) barrel extension, which together transform standard extrusion lines into microcellular extrusion lines. The technology is complemented by a range of delivery systems including Series S and Series K systems for precise gas injection, along with supporting components such as the Booster Box, Satellite Controller, Temperature Controller, Line Pressure Controller, Single Line Controller, and Splitter assemblies. The company also provides proprietary sheet and film dies optimized for microcellular foaming and true gauge control systems. This integrated hardware ecosystem enables manufacturers to produce lightweight plastic products using 15-20% less polymer while maintaining solid plastic performance characteristics.
