Pressing business: latest in thermoforming
Recent advances in thermoforming technology include a high impact material, a barrier coated film and a granulator developed specifically for processing skeletal waste. Lou Reade reports
Thermoforming is a dynamic, fast-changing area, so it’s no surprise that recent advances cover the whole spectrum of materials, machinery – and ancillaries. Oman Oil Refineries and Petroleum Industries
Company (Orpic) has launched a new polypropyl- ene (PP) thermoforming grade, which it says will increase the productivity and overall performance of transparent thermoformed cups, trays and containers. The material, called Luban HP1151K, uses Hyperform HPN-600ei nucleation technology from Milliken. It combines high clarity and aesthetics with a new level of superior dimensional stability for thermoformed products, says Orpic – offering the food packaging and household storage solutions industries a new standard in PP. As well as being able to increase the number of
articles that can be produced, the high quality finished products provide good stacking perfor- mance. It also offers a broad processing window that allows product quality and consistency advan- tages, as well as productivity benefits for converters.

Additionally, the grade delivers optimal environ- mental and handling-related advantages associ- ated with using lightweight PP compared to other materials, says Orpic. “Luban HP1151K reduces haze in the product
and increases clarity and gloss,” said Gilles Rochas, general manager for polymers at Orpic. “We are confident that it will help international packaging customers reduce their cycle times and achieve better results through less wastage – while offering all-round productivity improvements.” Hyperform HPN-600ei also offers good organo- leptics with no contamination risk – making Luban HP1151K suitable for food applications.
