What determines the haze level of a clear film
Haze is greatly influenced by material selections and product design. Resin characteristics, such as crystallinity and molecular weight distribution, have a key impact. Copolymers are generally hazier than homopolymers. Additives and coatings usually contribute to increased haze. All other things being equal, thicker films will be hazier than thinner films. Additional variables, like process temperatures in the different stages of film-making, can further affect haze, so they are tightly controlled.
