PVC stretch film for food purposes or cling film is an innovational packaging material. It is used as a one-shot package for food products since it prolongs their shelf life and makes it possible to pack hot food. The film of such type has a unique capability to let the vapour and CO2 out and let the oxygen in. In such a way it prevents the condensate formation in a package and bacterial growth. PVC film has a special micro-structure that allows the packed product to “breathe”. Therefore the sweating, which may appear right after the packing, disappears within a short space of time and the film becomes crystal clear. The packing of warm food products increases the elasticity of PVC film and after the film gets cold, the settling effect appears making the product look good, prolonging the lead time to several days and preserving the tastiness and aesthetic characteristics of products.
