Borealis and Borouge have launched an advanced grade of their BorPure high density polyethylene (HDPE) family to support the global beverage industry’s lightweighting trend for caps and closures.
The BorPure MB5568 grade, which was launched in Europe in early 2014 and will be officially launched in Asia at the upcoming Chinaplas, is based on Borealis’ proprietary Borstar polyethylene (PE) technology and designed to produce caps and closures for carbonated soft drinks, juices, teas and bottled water, particularly to complement the industry’s widening adoption of lightweight, standard short-neck closures (PCO 1881). The material features improved stiffness and Environmental Stress Crack Resistance (ESCR), which enables additional cap and closure downgauging with consequent material cost savings. As a multimodal polymer, BorPure MB5568 has a flow equal to that of benchmark monomodal MFR 2 HDPE resin. In addition, all BorPure grades offer very good organoleptic properties and has no taste or odour influence on bottle contents.
