Plastic Ingenuity in Cross Plains, Wis., which operates five thermoforming plants and builds its own machines, has patented pressure-forming tools that round the edges of medical trays. The “SafeEdge” method adds cost but prevents the tray from accidentally slitting a sterile pouch and exposing a high-value medical device to airborne contaminants. The SafeEdge process (U.S. Pat. 7232541 2007) forms a projecting ridge around the outside of the tray with a corresponding undercut that bends the ridge inward at an obtuse angle. The process uses proprietary trim tooling for PET, PETG, or HIPS. (608) 798-3071 • www.plasticingenuity.com
