Two companies, Swedish compounder Polykemi (www.polykemi.se) and German extrusion blowmolding machinery manufacturer Bekum (www.bekum.de), have teamed up to test the processability of calcium carbonate-filled polyethylene (PE). The result is a material being marketed as ‘EcoScan’, which the companies think may meet market acceptance as a potential replacement over conventional high-density polyethylene (HDPE) for foodstuff containers.
According to the development partners, processors choosing the material will be able to blowmold packaging with good barrier properties, UV protection, and at a cost that may make them smile. Using the company’s fully electric Eblow 206 D blowmolding machine, Bekum has tested a dual-station machine running a three-layer bottle at a rate of 5220 200-ml milk bottles per hour. EcoScan already has FDA food-contact certification.
