A mold is disclosed for forming a freezable and thawable bag of uniform thickness, especially useful for cryopreservation of thermolabile substances. The mold features one or more recessed planar surfaces, including radiused peripheral walls about the recesses, a planar top surface, and means for conforming a blank sheet to the mold. Two mold halves combine to form a completed bag. The mold halves may be complimentary.

[ I claim:] [1.] A medical bag mold for forming medical bags which resist breakage especially when exposed to a phase change, comprising, in combination:a recess defined by a planar surface, a radiused periphery circumscribing said planar surface in order to provide force dissipation of the bag at its periphery and a peripheral support circumscribing said radiused periphery and oriented parallel to said planar surface, andmeans for conforming a plastic sheet material blank to maintain a contour of the mold such that the conformed plastic sheet material results in a break resistant medical bag, having a complemental planar surface, radiused periphery and peripheral flashing circumscribing said radiused periphery.
