Film-paper fiber layer laminate and process for preparation thereof
Abstract:
Disclosed is a film-paper fiber layer laminate comprising a film and a very thin paper fiber layer bonded to the surface of the film. This laminate is prepared by bonding films to both surfaces of a paper so that the adhesive bond strength between the film and the paper is higher than the failure strength of the paper fiber layer and separating the films by delamination. This film-paper fiber layer laminate is excellent in the transparency and dimension stability, and the tearing strength of the film per se is completely retained and the laminate is suitably used as a tracing paper.
