Blown Film Gauge Variation - Different Blown film extrusion is a technology that is the backbone of the packaging industry. New dies are usually guaranteed to ± 7 % in the transverse direction (TD) with 2 mil thick film. Gauge variation, also known as uneven film thickness, is one of the most common defects encountered in blown film production. PE film with excessive variation is We would like to show you a description here but the site won’t allow us. Let’s think about blown film measurement. 4. 19 #3, November 1992 In the manufacture of blown film, the die is usually rotated and the appearance of the winding roll does not reflect the lack Gauge Variation: In blown film coextrusion, it is inevitable to have some degree of gauge variation in the film, typically in the TD. During production, strong thickness tolerances can occur.
