For converters considering whether to invest in a triplex machine like the TRI-1300A versus sticking with duplex machines, the comparison comes down to efficiency and quality:

• 
  

  Efficiency: Running a PET/Foil/CPP structure on a duplex machine requires: Run 1 (laminate PET to Foil) →→ Rewind →→ Move roll to second machine →→ Run 2 (laminate PET/Foil to CPP). The TRI-1300A does this in one continuous operation, effectively doubling the output for three-layer structures.

  Quality Control: With two-pass lamination, the adhesive on the first pass is fully cured by the time the second pass occurs. This can sometimes lead to poor secondary adhesion. On the TRI-1300A, both adhesive layers are applied and cured together, often resulting in better interlayer bond strength.

  Factory Footprint: While a triplex machine is larger than a single duplex, it is significantly smaller than the space required for two separate duplex machines and the staging area for intermediate rolls.
