Methods of increasing the haze of a thermoplastic film include incrementally stretching thermoplastic films in the machine direction. In one or more implementations, methods of incrementally stretching thermoplastic films include reducing the gauge of the films without reducing the films' haze. The methods can involve cold stretching the films and imparting rib patterns into the film. The linear ribs can have alternating thick and thin gauges. Incrementally stretched thermoplastic films can have a haze that is approximately equal to or greater than the haze of the film prior to stretching.
