[0034] Such as figure 1 As shown, it reflects the arrangement of each layer of the high temperature sterilization-resistant medical device blister packaging film of the present invention. It can be seen from the figure that it has a five-layer structure in terms of material composition. The first to fifth layers are heat-sealing layer A, sub-inner layer B, core layer C, adhesive layer D, and weather-resistant layer E.
