STATIC CONTROL | MACHINERY Shock treatment:
keeping control of static electricity
Keeping static under control is critical if film and sheet extruders are to maintain product quality – on everything from blown film to rigid sheet
Film and sheet producers must handle a myriad of production problems in order to ensure high product quality, and one of the most pervasive is that of static electricity – which is commonly gener- ated on fast-moving lines and must be removed. Recently, Material-Plastik – a Hungarian flexible
packaging and label manufacturer – installed an anti-static bar from Meech International to overcome static generation problems. “Static charges are a big problem for consumer
packaging manufacturing – but this can be solved with the right technology,” said Attila Nemeth, sales manager and head of technical support. “Meech static control bars have been integral to solving this problem in our business for over six years.” Installed on Material-Plastik’s extruder and printing lines, Meech’s Hyperion 924IPS short-range and Hyperion 929IPS mid-range antistatic bars have helped prevent static and contamination build up. “Today, we use these products on all our
extruder and printing lines, and they have com- pletely eliminated static charge,” he said. In similar fashion, a leading North American
producer of flexible packaging for perishable foods turned to Meech to help it keep its produc- tion lines free of static electricity problems. The company has installed eight Meech Hype-

rion bars – four 929IPS models, and four 971IPS-15 models – plus 56 bulkhead nozzles, to help it remove static from its flexible packaging lines. With barrier films forming such an integral part
of its flexible packaging range, consistent produc- tion is essential in the factory and the generation of static poses a very real threat to this. “Our central trim system is a critical process that
supports production,” said the Canada-based company. “The presence of static in our separators and balers can trigger false alarms by covering photo-eyes that automate baler cycles or high-level diverters with material.” Meech’s Hyperion range of ionising bars are
engineered to include several key characteristics such as Ion Current Monitoring (ICM) technology, clean pin alerts, and adjustable output voltage, frequency, and balance. The 929IPS Mid-Range Pulsed DC Ionizing Bar and the 971IPS-15 Long-Range Pulsed DC Ionizing Bar provide the manufacturer with a solution to keep necessary production areas clean and free of debris, while ensuring production is kept flowing. “Static may cause trim to stick to a screen
located inside the separator, disrupting air flow and performance,” said the customer. “Continuous operation is necessary to keep work centres
