Cast Stretch Film

Cast Film - starts by having granular resin fed into a heated screw barrel. The molten resin is then fed through a narrow slot die. The dimension of the die helps determine the finished width and thickness of the film. The molten resin is then fed over a chilled roller which rapidly cools and solidifies the film. The film is then drawn through tension rollers to the slitting and winding stations.The philosophy behind manufacturing stretch film via the cast process has increased because it is the cheapest possible method of production
