Abstract
Multi-layer films, and processes to make the films, that enable the delivery of a substrate featuring a peelable thin layer of low haze, amorphous, isotropic film with the desired properties of high modulus, high usage temperature, UV blockage, and toughness. The films are made using a co-extrusion, co-orientation and annealing process to enable the delivery of a thin isotropic, UV blocking layer on top of a release layer and support substrate. These film constructions can be kept together during additional processing steps such as coating and converting. The release and dimensionally stable substrate layer can be easily removed once processing steps are completed.
