Abstract
It has now been determined that an internal optical defect can be eliminated by controlling the relative speed mismatch between the resilient roll and the casting roll in a film extrusion coating process. In particular, slowing down the surface speed of the resilient roll relative to the casting roll when coating a biaxially orientated film was found to remove the optical defect. Conversely, speeding up the surface speed of the resilient roll relative to the casting roll when coating a uniaxially orientated film was found to remove the optical defect.
