One of the most exciting innovations in flexo today is the carbon fiber chamber blade system. Carbon fiber is extremely strong and much stiffer than aluminum by as much as 300%. Not being steel or aluminum, carbon fiber will not corrode and is resistant to all types of inks, solvents and adhesives.
They are generally easier to clean up and require much less water to rinse clean than conventional materials. Newer designs with carbon fiber systems usually mean the chamber does not need removing to replace the doctor and retaining blade. They can be up to 70% lighter than aluminum and even greater when compared with steel. This makes them much easier to handle and can often be lifted in and out of a machine if needed by one operator.
