The blown film process is being used for more and more high quality and advanced films whereas historically it was employed typically for basic, lower quality commodity films.

This progress has been enabled by the development of better-quality processing equipment and polymers. 

Industrial gauging has also developed so where lines used to be run with no gauging or at best with slow gauges mounted on the bubble above the frost line today extrusion companies are investing in faster and more accurate measurement systems which are mounted on the lay-flat.
