Borealis launches random copolymer PP for rigid packaging applications

Borealis has introduced its high-flow random copolymer polypropylene (PP) RJ901MO to the rigid packaging market.
The company said the material can be used for thin-wall packaging and houseware applications, such as storage boxes, CD and DVD cases. The grade is manufactured using Borealis' proprietary Borstar technology.
The material has a melt flow rate (MFR) of 110, which enables lower processing temperatures. For packaging converters, this creates the potential for increased productivity through optimized cycle times and energy savings. Compared to MFR 70 materials, it is possible to obtain a 20ºC reduction in melt temperatures resulting in a 20% cycle time reduction.
When compared to MFR 70 materials, the material has a 10%-15% reduction in maximum injection molding pressure.
Borealis states the RJ901MO offers a good balance of stiffness and impact performance comparable to that of MFR 70 random copolymers at ambient temperatures, which allows stable stacking of finished articles. The flow and stiffness combination also makes the material qualified for the production of complex shapes or long, narrow lengths.
Borealis touts the material's high transparency, gloss, and a non-yellowing effect. Transparency is achievable also at low processing temperatures.
"The launch of RJ901MO reinforces our commitment to provide the rigid packaging market with value-added, sustainable solutions for the value chain," Rainer Höfling, Borealis, VP business unit molding, said in a statement. "The potential for lower temperature processing created by the grade's superior flow results in clear productivity advantages for converters and more environmentally-considerate processing, with converters able to offer the market finished articles displaying highly-appealing transparency."
NPE2012
At NPE2012, Borealis will showcase some of its products together with its machinery partners. Borealis resins will be demonstrated on the stands of Engel Austria (booth #943) and Arburg (booth #3927).
Some of the products featured include:
BorPure MB6561, which was developed to meet specific cap and closure needs for still and sparkling water and carbonated soft drinks. The company claims it offers benefits in terms of processing for the converter, and enhanced aesthetics for the brand owner. It is based on multimodal technology that gives improved organoleptic behavior with very low taste and odor.
Designed for the healthcare market, Bormed RG835MO is a specially modified polypropylene random copolymer with a high melt flow rate, characterized by good processability, high transparency, controlled low friction, and high stiffness-impact balance at ambient temperatures, the company stated. This grade can be sterilized with ethylene oxide or steam and has a high chemical resistance and solid printability. |
