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.

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.

Computer simulation of the load test of an extrusion blow moulded product
MATEC Web of Conferences, 2018 The results of compression "top load" test of an extrusion blow moulded container, performed in ANSYS Mechanical software, were presented. The non-uniform wall thickness of the blown product was considered because the thickness distribution was the ...

An experimental study on process-oriented scale-up/scale-down in blown film extrusion [PDF]
AIP Conference Proceedings, 2020 The transfer of experimental test results from a small-scale system to a large-scale production system is known as scale-up or, conversely, scale-down. For film-producing companies, scale-up is a common procedure in the development process of new composite films or material recipes, where the main objective is to obtain equal film properties in the ...

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.
