    摘要: A system and a method for providing a film having a matte finish. The system includes means for providing a coated substrate, the coated substrate comprising a first coatable material applied to a substrate, the coatable material forming a first major surface of the coated substrate; means for changing the viscosity of the first coatable material from a first viscosity to a second viscosity; a face-side roller having an outer surface positioned to contact the first major surface of the coated substrate to impart a matte finish thereon; and optionally, means for hardening the first coatable material. The method of the invention includes the steps of (1) providing a coated substrate comprising a coatable material disposed on a substrate, the coatable material providing a first major surface of the coated substrate; (2) changing the viscosity of the coatable material from the initial viscosity to a second viscosity; (3) contacting the first major surface of the coated substrate with at least one face-side roller to impart a matte finish; and (4) optionally, hardening the coatable material to provide the film.

    摘要: A system comprises a slot die including an applicator slot extending about a width of the slot die, wherein the applicator slot is in fluid communication with a fluid flow path through the slot die, and a plurality of actuators spaced about the width of the slot die, wherein each actuator in the plurality of actuators is operable to adjust a cross-directional thickness of the fluid flow path at its respective location to provide a local adjustment of fluid flow through the applicator slot. The system further comprises a controller configured to set the position of each actuator according to one of a plurality of discrete settings for operation of the slot die. The controller is further configured to, using fluid dynamics and a digital model of the die, predict a set of discrete settings from the plurality of discrete settings corresponding to a preselected cross-web profile for the extrudate.
