An additional output increase becomes possible by using PLAST-CONTROL’s double air ring technology, PRO-CON DUO. Mechanical properties can be improved using DUO as well.

The Electrical controlled upper air ring elevator allows easy adjustment and accessibility. The combination of “improved output – better mechanical properties” ensures a fast return on investment


  • High bubble stability
  • Perfect basic tolerances
  • Significant higher output
  • Fast return of investment
  • DUO air ring for increased film strenght and higher outputs (machine permitting)
  • Better mechanical film properties
