Borealis and Borouge introduce a lightweight BorPureTM PE innovation for caps and closuresBorealis and Borouge, leading providers of innovative, value-creating plastics solutions, 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.
BorPure MB5568 brings a lightweight innovation to caps and closures for carbonated soft drinks, juices, teas and bottled water. The grade was launched in Europe by Borealis in early 2014 and will be officially launched in Asia by Borouge at Chinaplas in April. Based on Borealis’ proprietary Borstar® polyethylene (PE) technology, BorPure MB5568 is designed particularly to complement the industry’s widening adoption of lightweight, standard short-neck closures (PCO 1881) that bring savings for the total packaging.
The unique Borstar platform allows the tailoring of PE mechanical and processing properties to match specific application needs without performance compromises, using less material. This advantage is further enhanced by the improved stiffness and Environmental Stress Crack Resistance (ESCR) exhibited by BorPure MB5568, which potentially enables additional cap and closure downgauging with consequent material and production cost savings, as well as contributing to carbon footprint reduction and, therefore, sustainability.
“Cost reduction in bottle production is a key factor in competitiveness for the beverage industry and lowering the volume of material used in caps is a focus element of that initiative,” comments Russell Tew, Borealis Marketing Manager, Advanced Packaging and Fibre. “BorPure MB5568 has been developed jointly by Borealis and Borouge to positively aid that objective by allowing converters and brand owners globally to further reduce the amount of plastic, which is contributing further to the cost-reduction initiatives taking place in the beverage industry.”
Also of primary importance to the consumer is the ‘as bottled’ taste of the product. BorPure MB5568, as all BorPure grades, offers excellent organoleptic properties and has no taste or odour influence on bottle contents – a parameter monitored to ensure consistent batch-to-batch quality.
As a multimodal polymer, BorPure MB5568 has a flow equal to that of benchmark monomodal MFR 2 HDPE resin. The advantage of the material is also evident in its enhanced ESCR performance, giving a 50% improvement on the already outstanding ESCR of its predecessor BorPure MB6561.
“Borealis and Borouge, as the leading suppliers to the caps and closures industry, work continuously to identify changing market demands and deliver timely solutions that benefit the whole value chain from converter to consumer,” adds Rainer Hoefling, Borealis Vice President Advanced Packaging and Fibre. “BorPure MB5568 offers a new level of packaging total cost performance efficiencies in line with that goal.”
From April 23-26, 2014, Borouge will be participating in Chinaplas 2014 in Shanghai, China, and will officially launch MB5568 at the event.
From April 28-30, 2014, Borealis will be participating in and sponsoring the Plastic Closure Innovations Conference in Berlin, Germany, and giving a presentation about HDPE and PP solutions to the challenges of the caps and closures industry.
