NPE2015 will mark the North American debut of the Mirex-MT-V polishing stack for cast film and sheet from Reifenhauser. The stack can reportedly produce PET film thicknesses of 120 microns or less. Previously, specialized equipment was required to produce PET film any thinner than 150 microns, according to Reifenhauser. The reduction in thickness allows producers of blister and display packaging to cut material costs. The newest generation of the stack can also accommodate PS and PP production.

The polishing stack also is equipped with features that allow processors to reduce product changeover times and rejects by about 80% and to digitally adjust the nip more precisely by a factor of 10, automatically during running production. All set data are 100% reproducible.
