Polyester’s Flexibility allows ink BACK into the Chamber
Steel blades are stiff and rigid, therefore they struggle with allowing ink to pass underneath the blade and back into the chamber. This causes ink to build up on the back side of the blade, pool at the end of the chamber and eventually sling onto the press and web.
Printers can eliminate trail doctoring by using polyester containment blades. The polyester material is equally effective at containing ink in the chamber but thin and flexible enough to let back-doctored ink return to the chamber.

TruPoint Polyester will not Damage the Anilox Roll
A costly concern with using steel doctor blades is the potential for anilox roll scoring. Polyester containment blades will not score or damage anilox rolls. The material is soft and contains no sharp fragments which can break off, become lodged against the roll and destroy the engraving as the roll turns. The material is non-abrasive and won’t cause excessive wear on the roll.

TruPoint Polyester Outlasts Steel Containment Blades
TruPoint plastic and polymer blades are generally known to outlast traditional steel blades, due to the natural durability of plastic. The TruPoint Polyester blade material is extremely flexible, resilient and abrasion-resistant, allowing this containment blade to outlast steel.
TruPoint Polyester is more Eco-Friendly than Steel
During production, polyester containment blades emit a small percentage of carbon dioxide compared to steel blades. The added features that reduce ink and substrate waste, also contribute to the green aspects of polyster. Using polyester containment blades can help printers meet requirements for reducing their carbon footprint.

TruPoint Polyester is Safe to Handle
You can significantly reduce press room injuries by replacing steel containment blades with safe TruPoint Polyester blades. The properties of the blade material reduce the risk of injury when installing and removing blades from the press. Polyester containment blades may be used with steel doctor blades, but combining polyester blades with any of our TruPoint doctor blades significantly reduce the risk of injury to operators and the anilox roll.
