Wrapping film made from a polyethylene
Hygiene is one of the most important demands made on the production facilities when it comes to the production of foodstuffs. faigle Kunststoffe GmbH, Hard, Austria, has therefore developed a wrapping film made from a polyethylene (grade: PAS-PE) with added steriones. This film is used in prefermenting cabinets to guarantee hygienic conditions for raw bakery products.
Steriones are metal organic substances with an ionizing effect. They provide protection against a wide range of health-endangering micro-organisms such as molds, bacteria, germs and viruses. Furthermore, the protection is maintained over a prolonged period of operation. The steriones mostly prevent germs settling on the surface of the film at all. If, for example, for mechanical reasons – e.g. due to scratches – germs do settle on the film surface, the metal organic substances disrupt the energy metabolism of the micro-organisms so that they die off. In the medical and clinical sector, steriones, that are harmless to humans, have been in use for many years. Even under the strict rules of the American Food and Drug Administration (FDA) they are included on the positive lists and regarded as generally safe. Their effect is quick and lasting, and nevertheless they develop no toxicity.
For easy separation of the bakery products, the surfaces of the film and the underlying surfaces of the guide elements are structured with longitudinal grooves.
