With
increasing film thickness as well bowon film lines, air- and watercooled,
run into their limits. Therefore films in a higher thickness range,
wich starts depending on product and resins at 150 to 250 microns, are
produced by means of polishing. Each application deserves a tailor cut
solution, which can be supplied at low prices because of the soct consions
modular PLAMEX technology.
