Borealis, the Austria-based provider of chemical and innovative plastics solutions, has launched its BorLite linear low density polyethylene (LLDPE) range claiming to give flexible packaging converters a unique opportunity to gain a further competitive edge in efficiency, environmental and product performance.According to the company, BorLite sets new standards in the performance of Machine Direction Orientation (MDO) films. Based on Borealis’ proprietary Borstar LLD bimodal technology, the range was developed specifically to optimise the enhanced film properties and production efficiency benefits created by MDO processing technology.
BorLite offers step-change downgauging, high impact strength, high puncture resistance, and good tear resistance in machine direction, in addition to lower operational costs and reductions in energy and CO2 emissions. It brings trouble-free, smooth operation to the MDO process, giving the flexibility for film performance properties to be tailored.
The BorLite range includes three grades to suit the needs of different applications: BorLite OPE792, BorLite OPE795 and BorLite OPE797. Trials in the heavy duty shipping sacks (HDSS) sector highlight the outstanding potential of the BorLite / MDO combination. Demanding performance specifications for HDSS films plus the industry’s concern regarding operational costs, has resulted in a move towards thinner, high performance film, with less material used in order to reduce expenditure.
Compared to existing market solutions, BorLite and MDO offer the HDSS market same or higher film performance, packaging process improvements, outstanding material reductions, and associated cost and environmental benefits. Advances include a 38% thickness reduction from 130 mikrons to 80 mikrons, 50% increase in impact strength, high line speeds with up to 2000 bags/hour achieved, high load security during transportation and storage, a reduction of bag cost per unit, 37% weight reduction, 8% reduction in energy use to produce a unit bag for 25kg as well as 130 tons of CO2 emission reduction per 1000 tons of goods packed.
