Blown Film Line
All parameters of the system, e.g. extruder speed, temperature, haul-off speed, film width, film bubble ratio, etc. are stored in the touch panel control system, which guarantees the reproducibility of the film quality at any time.
Possible testable polymers include materials such as PP, PET, PC, HDPE and LDPE and can be in the form of pellets, powders and flakes.

Film Thickness Measurement (FTM)
The OCS Film Thickness Measurement (FTM) allows the continuous measurement of the thickness of
polymer film (flat film, blown film or tape). For measurement, the film is guided between two precision
rollers. One of the rollers is deflected according to the film thickness. This deflection is measured by
a digital probe and evaluated by microcontroller-based electronics. The measured value is shown on a
display and can be evaluated via analogue or digital interfaces.

Gloss Measurement (OGM)
The OCS Gloss Measurement (OGM) is designed for the constant and precise control of film gloss properties.
The measuring device is integrated into the Modular Film Analyser (MFA). It enables a continuous measurement
of the gloss value on polymer film. The gloss properties of films are analysed based on their different ability
to reflect light. A special LED lighting unit illuminates the continuous film while a photo diode measures the
strength of the reflected light. The measured amount of gloss, from matt to glossy, is given in GU (Gloss Units).
Features
- Robust, precise measuring unit
- Gloss measurement in GU (Gloss Units), matt to gloss
- Alarm function when limit value exceeds or falls below a specified range
- Continuous measurement of the gloss value as well as calibration according to ASTM D523, DIN 67530, DIN EN 14086 and ASTM D2457

Spectroscopical Measurement APLAIRS®
APLAIRS® (Analysis of Plastics by InfraRed Spectroscopy) is a spectroscopic method for
measuring additives, (co-)monomer compositions and chemical and physical properties in
the production of polyolefins. This concept allows the automation of the daily continuous
measurement requirements for quality control. For this purpose, the polymer film runs through
the APLAIRS® system, which is equipped with an FTIR spectrometer and specially developed software.
The measurement takes place in real time. The spectra are recorded and properties are predicted,
documented and graphically processed. The results can also be transferred to superordinate systems.
This ensures continuous quality control and documentation and the resulting reliable control of
various processes. The automated sample preparation leads to personnel savings and significantly
reduces labour costs.
Features
- Using the software, continuous recording of spectrums and prediction of analysis data (every three minutes)
- Robust and precise FTIR spectroscopy
- Conventional as well as multivariate analysis can be applied to predict the analysis data
Application Areas
- Analysis of materials, such as LDPE, LLDPE, HDPE, PP, ABS, PS, PET, EVA and PC
- Analysis of additives such as antioxidants, lubricants, UV absorbers, stabilisers, fillers, processing aids, etc.
- Testing of physical properties, such as density in polyolefin, thickness, etc.
