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.

A thin, biaxially oriented polyester film which is asymetrically oriented by stretching 1-2 times in the machine direction and about 3-5 times in the transverse direction in the plane of the film is disclosed. The film has a birefringence of at least 0. 085, an optical retardation of at least 9000 nanometers and a shrinkage of less than 2% in any direction at 150. degree. C. The film produced is substantially free of color fringes when viewed in partially polarized light. There are also disclosed two processes for the production of said film.

A calendering apparatus and method for heatsetting a traveling multi-filament tow basically utilizes plural heated rolls about which the tow travels in a sinuous path to be conductively heated by the rolls and, at each roll, a plurality of infrared lamps in an arcuate arrangement facing the portion of the respective roll in contact with the tow simultaneously applies infrared radiation to the opposite side of the tow. In one embodiment, this arrangement of infrared lamps is retrofitted to a conventional calendering apparatus. An alternative embodiment provides for reducing or eliminating the number of calender rolls followed by a series of infrared heating tunnels collectively effective to accomplish heatsetting of the tow. The speed and/or throughput rate of each calendering apparatus and method is effectively twice that of conventional equipment of similar size.
