Abstract
The present disclosure is directed to a process for recycling film materials, and is particularly directed to collecting spent release liners for labels and constructing new release liner stock from the spent materials. In order to use the waste film, the film is subjected to a process for increasing the intrinsic viscosity. In addition, a coloring agent may be incorporated into the film in order to mask yellowing. In one embodiment, a multilayered composite film is formed.
