Plastic films can be bent, molded, printed on and twisted into different shapes and designs that are not easily achievable with other materials. Its versatility is only limited by the imagination of the artist shaping and designing the film. Much like an artist, plastic film fabricators require a canvas to paint their picture. The most common and effective canvas is a white film, one that does not allow light to shine through, i.e, high opacity. There are several options to create the white plastic film. One technique is to add a material in the film construction that can alter or attenuate the light so that the light is scattered. Film producers most commonly use rutile TiO2 to make a clear plastic film opaque.
