1/17

Blown Film Unit 300

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.

A compact unit for blowing,

cooling, take off and wind up

of extruded hoses.

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

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.
