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 ...

Increased output of blown film extrusion lines by using a cooling sleeve [PDF]
AIP Conference Proceedings, 2014 Production efficiency is one of the most important demands in blown film production. In many cases, the cooling power is the limiting factor for an increased output. A possible solution for a better cooling is the use of a cooling sleeve right after the outlet of the die in addition to the conventional air rings and internal bubble cooling (IBC).

Impact of molecular architecture and draw ratio on enhancement of targeted mechanical properties of machine direction oriented polyethylene films produced after blown film extrusion [PDF]
Journal of Plastic Film & SheetingConventional multi-material multi-layer flexible packaging offers excellent properties. However, it has recycling challenges, necessitating a shift to mono-material multi-layer flexible packaging for example all-polyethylene (PE) packaging which can be ...

Blown film extrusion of poly(lactic)acid/poly(3‐hydroxybutyrate‐4‐hydroxybutyrate) blends for improved toughness and processability [PDF]
Polymer Engineering & Science, 2023 Poly(lactic acid) is one of the most commonly used bioplastics thanks to its mechanical performance and low environmental impact. Strategies to overcome excessive rigidity of PLA are constantly investigated.
