Influence of the nature of pro-oxidants on the photooxidation of polyethylene blown films
Heliyon, 2022 In an attempt to reduce the accumulation of polymeric waste in the environment, such as plastic bags, the use of pro-oxidants has been adopted in polyolefins, including polyethylene (PE), which is one of the most used polymers in film production.

Product-Related Process Data Acquisition in Blown Film Extrusion [PDF]
, 2022 In today’s advanced plastics processing industry, a quality-based control of an entire production line is desirable. This requires a product-related process data acquisition allowing to merge process data and quality data with high accuracy. In this context, an approach for the blown film extrusion process will be presented.

Interface analysis of three-layer co-extrusion blown film [PDF]
AIP Conference Proceedings, 2019 The three-layer co-extrusion blown film could combine a variety of different characteristics in the extrusion process and significantly decreased cost, therefore this technology is being applied more and more broadly. The flow channel geometry of three-layer co-extrusion blown film die was built and then meshed by ICEM CFD with all-hexahedral elements ...

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.
