Adhesive-backed polymeric film storage method and assembly

An adhesive-backed paint protection film assembly comprising:

• A transparent paint protection film comprising a polyurethane and having a back surface and a front surface, with a pressure sensitive adhesive bonded to said back surface, wherein said paint protection film is cut into multiple discrete adhesive-backed paint protection films, each said discrete adhesive-backed paint protection film having a surface area with a desired 2-dimensional shape and a closed peripheral edge that defines the 2-dimensional shape of said surface area;
• and
• a release liner having an outer surface and an inner surface, the adhesive on the back surface of each said discrete adhesive-backed paint protection film directly contacting, and being releasably bonded to, the inner surface,
• wherein said assembly is wound into a roll, with the outer surface of said release liner facing outwardly and the front surface of said paint protection film facing inwardly, said paint protection film will elongate at least 3% when subjected to an applied tensile stress of at least 6 MPa at ambient conditions, and said 2-dimensional shape is dimensioned to cover a corresponding area of at least one body part of a vehicle.
