A new scale-up/scale-down method for the blown film extrusion [PDF]
AIP Conference Proceedings, 2019 The development of innovative film products is a two-step process: New composite films or material recipes are first experimentally tested on a laboratory-scale blown film line, and then the results regarding process conditions and final film properties are transferred to a large-scale production plant.
