Glass interleaver paper formed of coarse fibers

The present invention is a paper for use as a slip sheet interleaver for protecting the glass surface， 15 to 60 lb/3，000 ft 2It relates to a paper comprising a sheet having a basis weight of， a bulk density of less than 0.75 g/cm 3 and an average fiber roughness of more than 0.18 mg/m. Compared to conventional interleaver sheets， these papers are produced from refined pulp with high roughness. A paper for use as a slip sheet interleaver for the protection of glass surfaces in which the paper comprises a sheet with a basis weight of 15 - 60 lb/3，000 ft2， has a bulk density less than 0.75 g/cm3， and has an average fiber coarseness greater than 0.18 mg/m. In comparison to conventional interleaver sheets， this paper is produced from a refined pulp having high coarseness.
