selected so as to maximize operation at these lower temperatures the multilayer film 10 is extruded onto a chill roller 42 which may be patterned so as to impart a pattern to the newly formed film 10 this is particularly advantageous to reduce the gloss of the film and give it a matte finish using a three layer film construction such as is shown in fig4 typically the multilayer film 10 as initially formed will have an overall thickness 28 of approximately 40 microns or greater with the first skin layer 18 and each skin layer 20 having an initial thickness of 3 microns or greater which collectively may be approximately 15 percent of the overall initial thickness in a construction as in fig4 from the co extrusion film apparatus 40 the film 10 may be directed to a film stretching unit not shown such as a machine direction orienter or u201c mdo u201d which is a commercially available device from vendors such as the marshall and williams company of providence rhode island such an apparatus has a plurality of stretching rollers which stretch and thin the multilayer film 10 in the machine direction of the film which is the direction of travel.
