Blown Film Line
The OCS Blown Film Line is used to carry out optical and physical property measurements of polymers in the production of high-quality blown films (blowing, cooling, laying flat, haul-off and winding). All parameters of the line, e.g. extruder speed, temperature, haul-off speed, film width, film bubble ratio, are stored by a touch panel control system, which ensures that the film quality is reproducible at any time. This is an important parameter for optical and physical on-/offline measurements, for use with gels, impurities, fibres and other contaminants, as well as for turbidity, transmission, gloss, density and additive measurements.
Possible testable polymers include, for example, LLDPE, LDPE, PP and HDPE.
Features
Cleaning positions of the Measuring Extruder (ME) can be approached via electric motor
Modular architecture of the Modular Film Analyser (MFA) to facilitate customisation of additional measuring and test devices
Automatic control of the bubble diameter according to the preset film width
Operation via touch panel with data trend as well as optical and acoustic alarm functions
All system parameters are monitored and saved in the touch panel control system
