Borealis Extends Range of High Performance Polypropylenes for Thin Wall Packaging

The new grade is the third in Borealis’s BorPure random PP family. BorPure grades RG466MO and RJ377MO have melt flow rates of 30 and 45 respectively.

Nov 25 2011 --- Borealis, a leading supplier of innovative and sustainable solutions for the plastics packaging industry, will introduce the latest addition to its range of BorPure random polypropylene (PP) copolymers with improved organoleptics at the Thin Wall Packaging 2011 conference on December 6-8 in Cologne, Germany.

BorPure RJ766MO is intended primarily for transparent injection moulded, thin walled food packaging. Its excellent organoleptic properties mean that it will not impart taste or odour to the packaged product. BorPure RJ766MO is the product of a combination of Borealis’ Borstar PP polymerisation technology and Borealis Nucleation Technology (BNT). Together these technologies produce a material with a tailor-made molecular weight distribution (MWD) and crystalline structure resulting in fast crystallisation and a good balance of stiffness and impact properties.

Energy savings are also achieved thanks to the material’s excellent flow characteristics, which enable processing equipment to run at lower temperatures than is possible with many competing materials with sufficient organoleptic properties. “With its high melt flow rate of 70, BorPure RJ766MO now brings energy saving advantages to containers with even the thinnest walls,” says Rainer Höfling, Borealis Vice President Moulding. “Given its excellent organoleptic properties, our new BorPure material is now the preferred grade for all types of food packaging.”

The new grade is the third in Borealis’s BorPure random PP family. BorPure grades RG466MO and RJ377MO have melt flow rates of 30 and 45 respectively. These materials have helped Borealis to strengthen its position as a market leader in thin wall consumer packaging in Europe.
