Abstract
The present invention is directed to a sterilization tray assembly for sterilizing medical instruments. The sterilization tray preferably includes a base tray and a cover. Also, a secondary tray may be mounted within the base tray. These components ideally include ventilation apertures to allow steam or vapor to pass through the sterilization tray assembly to effect sterilization of medical instruments stored therein. The components of the sterilization tray assembly preferably are made of a mineral filled polypropylene and most preferably is a homopolymer which is filled with calcium carbonate, 40% by weight. This material exhibits good heat deflection characteristics at high temperature while being relative inert to absorption of H.sub.2 O.sub.2 vapor.
