Borealis upgrades RJ901MO for rigid packaging

Borealis, a leading provider of innovative solutions in the fields of polyolefins, base chemicals and fertilizers, is offering tangible cost and performance-related benefits to its customers in the rigid packaging market thanks to the improved properties of its superior flow random copolymer polypropylene (PP) RJ901MO. 

Manufactured using Borealis' proprietary Borstar? technology, the RJ901MO grade was launched in 2012 and has already been tested and approved by customers for a variety of housewares applications in which high transparency, improved aesthetic appearance and good mechanical properties are essential. Customers also benefit from a high melt flow rate (MFR) of 110 and thus subsequent cost and energy savings.  

Products based on RJ901MO are visually appealing thanks to the grade's superior aesthetic performance in terms of transparency and gloss. Enhanced transparency may also be obtained at low processing temperatures. The grade also features a balanced mix of stiffness and impact performance comparable to that of MFR 70 random copolymers at ambient temperatures which allows for versatile use – an ideal profile for manufacturers such as Sunware BV.  

Sunware realises tangible benefits of RJ901MO Based in The Netherlands, Sunware BV is a leading manufacturer of plastic storage solutions for the home. When switching from the current Borealis grade RJ470MO (MFR 70) to RJ901MO (MFR 110) on a product in its popular Q-line series, Sunware obtained significant cost and energy savings. Due to the high flowability and good performance of the new grade, a lower processing temperature could be used, resulting in shorter cooling and cycle times and lower energy consumption. Temperature was reduced by 35°C and cycle time by 15.5%, resulting in energy savings of 7.7% and cost reductions of EUR 39.2 per tonne of material used.
