Unwinding a plastic web generates static electricity and gives electrical discharge shocks to operators. Static electricity will also attract ambient dust. The thermoform process also creates static and will cause further dust attraction and stacking problems. Simco static control blowers produce a gentle ionized air stream and eliminate the side effects of static charges. In line systems in particular suffer from the contamination on the film, particularly when the “cups” immediately after being vacuum formed are filled with a product; i.e. yogurt. To remove the contamination on the web just before vacuum forming, Simco recommends a web cleaner.
