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.

slide2

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

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“ )

Blow Film Unit 300- Blow Film Head / Blow Film Die

Standard dies

30 mm - 50 mm - 60 mm

- other diameter and on request -

  • Blown Film Head:
  • The blown head / blown film die is attached to the laboratory

means of a deflection head.

  • The long orifice land ensures good homogenization and

conveyance to the die outlet.

slide8

Applications for Polyethylen

  • 1 x mandrel D = 50 mm
  • 1 x orifice D = 51,0 mm =
  • > gap width of 0.50 mm -> LDPE
  • 1 x orifice D = 51.5 mm =
  • > gap width of 0.75 mm -> HDPE
  • 1 x orifice D = 52,0 mm =
  • > gap width of 1.0 mm -> HDPE
  • 1 x orifice D = 52.4 mm =
  • > gap width of 1.2 mm -> LLDPE
  • 1 x orifice D = 53,0 mm =
  • > gap width of 1.5 mm -> LLDPE
