The Materials, Compounding and Extrusion department of the SKZ Plastics Center in Würzburg is expanding its range of modular training courses to include “Specialist in Blown Film Extrusion”. Blown film extrusion has become indispensable in today’s world and requires extensive know-how to control the sometimes very complex processes. Depending on the area of application, certain film properties are essential, for example, to ensure gas-tightness in food packaging.

Division into compulsory and elective modules
This qualification – like all others offered by SKZ – is divided into compulsory and elective modules. This ensures that participants can select the appropriate dates depending on their time constraints. The courses in the compulsory module provide a comprehensive overview of the topics of blown film extrusion. In addition to the material plastic and the material types relevant for blown film production, the course also covers the process structure and, in particular, the process sequence. Particularly in the case of multi-layer films, there is a significantly higher level of complexity here compared to other extrusion processes.

Extensive practical component on in-house blown film line
Particular attention is paid to process control and error analysis. In the in-house technical center, the knowledge gained can be put into practice on a laboratory-scale blown film line, and training can be provided in the start-up and shutdown and optimization process. The main topics are rounded off by the elective modules, which can be chosen according to individual requirements. At the end, the knowledge imparted is confirmed by a written examination.
