Clear, rigid medical packaging that can be sterilized by autoclave steam without warping or shrinking. The packaging is made by extruding a crystalline thermoplastic like PET, then partially stretching the film, heating it, and thermoforming it into the final shape. This process limits crystal growth to small spherulites rather than large crystals that cause warpage. The film is then sealed around the device and steam sterilized. The spherulitic crystals provide clarity and strength, but the restricted crystal growth prevents warping during sterilization. The packaging can be made by coextruding layers of different thicknesses that are split and stacked by multiplier units to form the final multilayer structure.
