Target Group and Workshop Content:

To everyone who wants to learn more about blown film extrusion in theory and particularly in practice, Intertek offers an ideal training in the form of this workshop, taking place in the technicum and laboratory of Intertek Polychemlab. The workshop is ideal for beginning machine-operators, commercial professionals and managers from other areas that want to gain practical experience in this field.

First, theoretical aspects of machine techniques and raw materials PE and PP will be discussed, followed by the effects of machine settings, after which all these aspects will be demonstrated in practice in our technicum and laboratory.

On the second day we'll focus on the correlation between practical (real life) experience and test results from the laboratory. Test methods will be demonstrated in practice by means of performing real production measurements.
