Berlin-based blow molding machinery maker Bekum Maschinenfabriken GmbH and Swedish resin maker Polykemi AB of Ystad have created a new bioplastic made of a polyethylene with calcium carbonate filler.
Called EcoScan, the material replaces conventional HDPE for blow molded food containers.
The first fully electric blow molding machine, the Eblow 206 D, is being tested as a dual-station unit for three-layer coextrusion of EcoScan.
Bekum delivered a six-layer BM 206 DL machine to German pharmaceuticals company Gaplast GmbH before the Interpack trade show in April in Dusseldorf, Germany. Gaplast ordered a dual-station BM 206 DL with four extrusion heads and six extruders.
Gaplast is making pharmaceutical bottles with a bag-in-box design.
The machine features a centrally arranged extrusion head. To meet quality requirements for pharmaceutical bottles, Bekum engineers installed an additional bobbing hydraulic on the extruder for optimized control over the parison.
The extrusion was combined into a spiral distributor for the bottle — a side-fed die head with a heart-shaped, curved tube for the inside bag.
The company's U.S. operation, Bekum America Corp., is in Williamston, Mich.
