ABSTRACT:
A receptacle for handling contaminated waste for sterilization and subsequent disposal which is a pore forming sterilization bag made from a thermoplastic resin which has been embedded with either soluble materials or melt materials which respond to the temperature and moisture of steam sterilization to form pores in the bag, thus permitting the entrance of sterilant and the exit of air for sterilization of the waste. The melt materials are low molecular weight polymers such as carbowaxes. The soluble materials can be either organic or inorganic materials such as polyvinyl alcohol, polyvinyl acetate, polyvinyl pyrrolidone and various inorganic salts, such as sodium chloride.
