The Containment Blade: What it is and how it can save you money

One of two doctor blades used in a chambered coating system, the containment blade serves the function of containing the excess coating in the chamber and preventing it from leaking out of the chamber.  The blade has no relation to metering or print quality unless trail doctoring is occurring.  This can happen when the containment blade re-meters the anilox roll before it enters the coating chamber, causing misting or spitting onto the printing plate. 

The containment blade is a good place to economize: the blade does not impact the coating quality and, as a result, achieving a fine bevel is not a concern.  Plastic containment blades offer up to twice the blade life of steel and can reduce anilox scoring and help prevent trail doctoring.  A longer-lasting blade will save you time and money in terms of fewer blade changes and shutting the press down less frequently to install a new blade.
