20220137277 | Multi-Axis Polarizer Film For Anti-Counterfeit Applications And Method Of Making The Same - A manufacturing process that allows for the transfer of labels formed from polarizer film to end-use products. The polarizer film is covered by a masking layer that is typically die cut to create the labels from the continuous sheet of film. Here, an additional covering layer (or layers) of a relatively stiff material is disposed over the masking layer. The addition of the covering layer results in the processed polarizer film being less susceptible to damage (related to unwanted bending) during further processing and/or shipment. Advantageously, the covering layer improves the ability to remove individual labels from the film, particularly with respect to attempting to peel off the thin masking layer. | 05-05-2022 |
