Abstract
The present disclosure relates to a multilayer film may include a fluoropolymer based layer that may include a fluoropolymer based material, and an adhesive layer in contact with the fluoropolymer based layer. The adhesive layer may include a first ultra-violet (UV) absorber component. The multilayer film may have a lower ultra-violet light transmission (L-UVLT) of not greater than 1.0%, where the L-UVLT of the multilayer film is defined as the percent transmission between 200 nm and 360 nm. The multilayer film may further have a high ultra-violet light transmission (H-UVLT) of not greater than 5.0%, where the H-UVLT of the multilayer film is defined as the percent transmission between 360 nm and 380 nm. The multilayer film may include a visual light transmission (VLT) of at least about 50.0%, where the VLT of the multilayer film is defined as the percent transmission between 400 nm and 1100 nm.
