Cast Film Extrusion


From the definition of a supply to the start-up of the equipment, we work together with the customer with the aim to define the most suitable machine, polymers and process design for the customers' specific requirements.

The design concepts of PCE series include the following modular components for films of width up to 3000mm, monolayer and coextruded up to 5 layers:

  • Feeding systems with individual or centralized pneumatic loaders

  • Gravimetric dosing groups up to 6 components per extruder

  • Extruder with automatic screen changer and customized screen view according to material to convert

  • Gear melt pump between extruder and die

  • Co-extrusion feedblocks for online variation of layer ratio and layer distribution

  • Die-heads of latest generation

  • Chill rolls where extruded melt is transformed into a film and quickly cooled down

  • Gauge measurement equipment with β- or X-rays for manual or automatic adjustment

  • Film oscillation devices of our design

  • Corona treatment units

  • In-line slitting equipment

  • Surface, centre/surface and gap automatic winding unit series PW for top quality finished reels with no defects and very strict reel geometry tolerances

  • Edge trim recycling system with recovery of film trims by feed hopper or lateral extruder

  • Automatic shaft and reel handling units

Raw Materials & Finished Product Applications
Polymers of LDPE, LLDPE, mLLDPE, HDPE, PP can be efficiently extruded on PCE series of cast film lines for the manufacture of co-extruded films with up to five layers and thickness from 15 to 100 µm. These films find an impressive variety of applications:

  • Disposable hygienic products

  • Disposable garment

  • Stretch wrapping film

  • Agricultural and garden cover/wrap

  • Food packaging

  • General purpose films
