A method for producing an improved coextruded polymeric film is disclosed. First, a base layer containing a polymeric matrix and at least one additional layer on at least one side of the base layer are coextruded. If the coextruded polymeric film is to be opaque, the base layer also contains at least one cavitating agent. Next, the coextruded multi-layer film is cooled. Finally, the coextruded multi-layer film is oriented in at least the machine direction (MD). At least the base layer of the coextruded polymeric film contains a fluoropolymer. The inclusion of the fluoropolymer in at least the base layer of the coextruded polymeric film provides a more even distribution of polymer flow through a die, which in turns leads to improved film gauge uniformity.
