In order to plasticize PVC, the hard PVC powder is mixed together with a plasticizer in a heating mixer. The plasticizers reduce the hardness of the plastic but do not chemically bind with the plastic. Because of this they tend to be volatile which means that plasticized PVC does not generally remain soft forever. Soft PVC films are accordingly not suitable for outdoor use.

Even though most plasticizers are physiologically harmless, the use of plastics containing plasticizers in the foodstuffs sector or for children’s toys is not advised.

In addition to the conventional plasticizers, so-called flexibilizers are also used for making soft-PVC. These materials do make a chemical bond with the PVC and are therefore not volatile. “Flexibilized” PVC films consequently remain soft for a much longer time. PVC that has been plasticized in this way is referred to as “polymer plasticized PVC”. Unless otherwise stated, the soft-PVC semi-finished products that we have on offer are made from basic monomer plasticized PVC.

Adhesion film is a calendered, cadmium-free soft-PVC film which through molecular adhesion is able to stick to smooth surfaces without glue (e.g. window glass). The longevity of the film when used indoors is up to three years and in the outdoors up to 1 year in temperatures between -5° C and +70° C.

In order to attain a good amount of adhesive strength, the intended surface for application of the foil should be as smooth, clean and dry as possible. Cleaning with glass cleaner to remove any grease or other impurities is strongly recommended.

The film can be used in any number of ways: display window advertizing, decoration, lettering, surface protection (e.g. the display window on mobile phones), temporary advisory signs, pictures in windows (e.g. Christmas decorations), etc. For use in the realm of toys the film is certified as per EN 71/3.

For convenience when working with the adhesion film, it comes laminated to a smooth carrier board (200 g/m²). That way the films will not stick together when stacked, they can be easily cut (shears, blade, guillotine shears) and can be screen printed with PVC compatible inks without any problem (as an alternative method, UV offset). When attaching the film the ambient temperature should be 20° C because the film tends to lose its adherence when too cold.
