  1. Blown Film Unit 300 A compact unit for blowing, cooling, take off and wind up of extruded hoses. It is suitable for production of small films used by the food industry and in the packaging field where the application of big production machines is often not profitable.

  2. application • Production control: • Monitoring the dispersion performance of compounders or extruders used in batch production • Inspection of incoming goods for gels and color distribution • Inspection in polymer processing • Production: • Production of small films used by food industry and in the packaging field • Development: • For control of the maximum polymer extensibility • To monitor the suitability of polymers or polymer blends in the laboratory

  3. Blown Film Unit 300 with ALR - M station Combination with MBR Online rheometer to measure online MFR and Viscosity Machine Frame: The machine frame executed as a stable, movable and fixable support with a central telescope- type profile system. Easy installation of all components. The automatic lifting function enables the Blown Film Unit to be easily adjusted to any take-off height Lab – extruder with exchangable cylinder diameter and length ( D= 20 / 30 mm / 1“ )
