Avoiding fog on the surface of a transparent plastic film can be very useful in food packaging and on films used for the agricultural industry, in green houses, on glasses and helmets.
Anti-fog properties will keep your products looking as fresh as when they were wrapped, increasing the shelf appeal not only by preventing fog to be created on the surface, but also by giving the surface an exceptional transparency that is much better than the raw film.
The EASI-Plasma Nano Coating Technology creates Anti-Fog properties by applying an extremely thin silica coated layer with a thickness between 5 and 50 nm (0.005-0.05 microns). Some of the big advantages of applying a coating thickness that is only a fraction of the conventional coating are a reduction in consumables and elimination of the need for drying. This brings the running cost down to a level unmatched in the industry. Not only will the EASI-Plasma Nano Coating Technology bring down the cost per square area, but also the layer thickness will be uniform over the entire surface.
The most used way to create Anti-Fog properties today is by adding additives to the formula when extruding the film. The additives react with the water vapour and change the surface tension of the water, not the surface tension of the film. The downside to this method is that the additives on the surface wear out and “drip” causing contamination of either the product in the food packaging, or the soil and the crops when used for agriculture or in green houses. This is, however, not the case with the EASI-Plasma Nano Coating Technology as it is an actual coating, that does not wear off with time and consequently does not contaminate the product or pollute the soil.
