Extrusion International 1-2023

27 Extrusion International 1/2023 state-of- the-art materials BOPP and BOPET, a new opportunity is opening up with BOPE. • Several developments for PP mono-material packaging have been successfully launched recently: E.g. flexible pouches, where com - plex laminates are now substituted by all-polypropylene versions based on BOPP and CPP or even retortable applications. • Trials on the Brückner labora- tory line clearly showed that post- consumer waste recylate PET can be added to the virgin material in a proportion of above 50% without any losses in quality. • Line concepts for the production of BOPE films, also having the flex - ibility to produce BOPP films. Film producers can choose lines between a working width of 6.6 m and an output of 3 t/h, or a working width of 8.7 m and an output of 5 t/h. Specialty film lines: Further developments Special film lines from Brückner are in great demand worldwide, especially for the rapidly growing e-mobility and new energy sector. The patented simultaneous LISIM stretching process is ideally suited for the very efficient production of a wide variety of specialty films with the best properties: • Battery separator films and ca- pacitor films: In these segments, a further increase in the previous line width from 5.5m to over 6m and the associated increase in out- put of over 20% will take place in stages. • Green energy solutions are supported by Brückner’s special BOPET thick film lines, producing high performance solar backsheet used for photovoltaic panels. • Industrial films for a wide va- riety of applications: Insulating film, composite films, electrical enclosures for cables and wires, membrane switches in motors and transformers, window film, pro- tection and release film, motor in- sulation film. • Flexible and printed circuits and electronics: Substrates for RFID antennas, organic displays, organic photovoltaic, medical sen- sors, printed batteries.
