A method of producing a multi-layer product that includes an extruded polymeric layer comprising an enhancer composition is disclosed. The disclosed product is produced by applying an enhancer composition (25) onto a transfer surface (22), such as that of a chill roll (12) on an extruder station (10), and then contacting the applied transfer surface against molten polymer (24) either before or during extrusion process of the molten polymer onto a substrate (20). The enhancer composition may impart functional and/or decorative properties to the treated substrate. When desired, the enhancer composition may be applied onto the transfer surface using an electrostatic spraying device.
