  • Process for manufacturing glazed paper
    Patent number: 6264794
    Abstract: The process is used for the production of high-quality glazed paper and includes the three process sections, stock preparation (1), paper formation (2), and glazing (3). According to the invention, the paper fibers used in the performance of the process are subjected to fiber loading, such that substances which reduce the compressibility of the fibers are incorporated in the cavities of the fibers. In combination with the glazing process (3), a paper with particularly high optical quality can then be produced.
