One method for making a laminate material comprising a first surface layer comprising resorcinol arylate polyester chain members and a second surface layer suitable for bonding to a substrate, comprises co-extruding a polymeric first surface layer material and a polymeric second surface layer material through a die and into the first nip of a calender roll stack comprising a first surface roll and a second surface roll that define the first nip, to form the laminate material. A nip load in the first nip of greater than or equal to about 400 N/cm can be applied to the laminate, and the laminate material can be collected from the roll stack. The first roll and the second roll can each have a surface smoothness of less than or equal to about 5 micrometers and temperatures of about 40&#xb0; C. to about 150&#xb0; C.
