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, fibers 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.

Testable Raw Materials

• Pellets, powder and flakes

Module I + II (included)

• Film Surface Analyzer (FSA100V2/FSA200V2)

Features

• Cleaning positions of the Measuring Extruder (ME) can be approached via electric motor
• Modular architecture of the Modular Film Analyzer (MFA) to facilitate customization 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
