All CenterPointLock skin barriers feature the unique Floating Flange and CenterPointLock closure, which ensure the highest degree of confidence, comfort, and security. All CenterPointLock pouches feature odor-barrier Quiet Film - an advanced pouch film (exclusive to Hollister), that minimizes the noise generally associated with ostomy pouches. Pre-cut openings with built-in convexity means added security and skin protection for recessed, retracted and flush stomas. The Floating Flange eliminates pressure on sensitive post-operative abdomens, while the CenterPointLock feature prevents unintentional pouch - skin barrier separation. Porous paper adhesive allows the skin to breathe.
