So far, the PQMex® tests recyclate using blown film. Many processors, however, produce on cast lines – for example stretch and wrap films or packaging films. For them, we are planning the PQMex® – Cast. The project is still a concept; implementation is expected next year.
Testing as in your own production
With the PQMex® – Cast, the melt leaves a flat die and is cooled on a chill roll to form a flat film. The material is thus tested under conditions that correspond to the later processing method. Gels, fisheyes and contamination are to be detected before a batch reaches the cast line – where they cause visible defects or web breaks.
Built like the PQMex®
The basis is a cast laboratory line that we are rebuilding along the lines of the PQMex®: single-screw extruder, flat die and chill roll, followed by camera and LED lighting, haul-off, winder and edge-trim winding. Operation and equipment are taken over from the PQMex® – the touch monitor, for example, is the same.
Proven inspection technology
The evaluation is the same as on the PQMex®: CAMEN detects and classifies the defects, the material is assigned to quality grades, and the results are available in vSTAT on request.
