Blown film lines P



WBL 400 P, WBL 600 P

These lines are designed for the production of films. The radial distribution system provides accurate thickness distribution, the vertical extrusion in a water cooling ring guarantees optimal transparency of films.

Several extruders in an elevated position discharge into a multi-layer die. The hose is guided downwards into a water cooling ring. After that, it is laid flat, dried if necessary, positioned or cut and then wound on rolls.

Advantages of the procedure

  • From the production of the hose up to the welding of the bag, the inner surface of the bag remains clean.
  • By shock-cooling, the clearness of the PP compound is reached.
  • A material with even orientation is produced.
  • By selecting suitable materials for the different layers, desired characteristics are optimally adapted to the requirements.
