Anti-fog flexible packaging
Fogging is a phenomenon observed commonly in applications of plastic films in the food packaging specially in the fruits,salad and vegetables packaging The term Fog describes the condensation of water vapour, in the form of small discrete water droplets, on a plastic film surface when an enclosed mass of air cools to a temperature below its dew point. The extent of the phenomenon depends on the actual temperature and relative humidity of the enclosed air mass, as well as the temperature of the plastic film.
Fogging reduces the consumer's ability to see the product and will give an impression of lower quality. In some applications condensation of water within the packaging may lead to actual reduction in quality.
