    Abstract: In one embodiment, a method for making a film comprises: heating thermoplastic to above a glass transition temperature of the thermoplastic; passing heated thermoplastic through a die and onto a polished calendaring roll and a resilient calendaring roll, and passing the heated thermoplastic between the polished calendaring roll and the resilient calendaring roll to form the film. The resilient calendaring roll has an average roll surface roughness of about 0.5 ?m to about 0.9 ?m. A nip pressure between the calendaring rolls is about 100 kPa to about 2,000 kPa. The film has an average film surface roughness of about 0.5 ?m to about 0.9 ?m, a gloss of less than or equal to about 10, an average stress of less than or equal to about 60 nm, and a stress spread of less than or equal to about 50.
