Current status of the Korean paper industry has been described with an emphasis on fibrous raw materials. Technological developments for utilizing more domestically recycled fibers and high yield pulps in papermaking has been discussed covering newsprint, linerboards, fine papers, etc. Peroxide bleaching characteristics of TMP's from Pinus densiflora and Pinus radiata was investigated and the effect of the amounts of hydrogen peroxide, sodium hydroxide, sodium silicates and chelating agents on brightness improvement, are discussed.
