Filmtek Film is known to be generally superior to paper as it allows for a more uniform and consistent abrasive coating. Not only is film waterproof, it provides better flexibility and durability offering a two, to sometimes three times longer lifespan than paper, for certain applications. Moreover, it performs as well on wood as on metal. Until now, film was twice as expensive as paper, but new technological advancements have allowed Uneeda to offer Filmtek at prices comparable to those of paper.
