Abstract:
Blown film extrusion is a process requiring a high level of operator
skill. Producing film to geometric specification requires a good
understanding of the dependence of bubble dimensions on the interrelationship
of process variables. Dimensions include film thickness, bubble
diameter, and frost line height. Process variables for controlling
these dimensions include screw speed, nip speed, cooling air speed,
and bubble air volume. An experienced operator understands that
changing any one variable will affect all three dimensions, and
understands the change that will result. A highly realistic blown
film extrusion simulator has been used to elucidate these interrelationships
for all personnel.
