Abstract (en)
The present invention provides as a first feature thereof a process for producing paper which is characterized in that material paper is passed through a nip provided by a metal roll and another metal roll under a linear pressure of 200 to 2500 kg/cm. The present invention provides as a second feature thereof a paper which is characterized in that the paper is produced by forming a coating layer containing a moisture-proof resin is formed on both surfaces of material paper before or after the material paper is passed through a nip provided by a metal roll and another metal roll under a linear pressure of 200 to 2500 kg/cm. The present invention provides as a third feature thereof a paper which is characterized in that the paper is produced by incorporating an interfiber crosslinking agent for cellulose into material paper, and thereafter passing the material paper through a nip provided by a metal roll and another metal roll under a linear pressure of 200 to 2500 kg/cm. The present invention provides as a fourth feature thereof a process for producing paper comprising at least two laminated sheets of paper, the process being characterized by passing at least two sheets of material paper through a nip provided by a metal roll and another metal roll under a linear pressure of 500 to 2500 kg/cm.
