ABSTRACT:
A multilayer polymer film includes first and second polymer layers. The first polymer layer includes a first ultraviolet radiation absorber. The second polymer layer overlies the first polymer layer and includes a second ultraviolet radiation absorber. The first ultraviolet radiation absorber has a peak absorbtivity wavelength less than 300 nm and the second ultraviolet radiation absorber has a peak absorbtivity wavelength greater than 300 nm.
