Indigenous Cellulosic Raw Materials for the Production of Pulp, Paper and Board. Part XXII - Wrapping Papers from Trema orientalis Blume

Laboratory experiments on the production of sulphate and soda pulps for wrapping papers from Trema orientalis Blume (kargol) are described. Results of pilot plant experiments are also included. These experiments have shown that Trema orientalis is a promising raw material for the production. Of wrapping papers in high yields and of satisfactory strength properties. Since this wood is short-fibred, it will be necessary to mix a suitable quantity of bamboo Sulphate pulp with kargol pulp for manufacturing wrapping papers on commercial paper machines. Six samples of wrapping papers from Trema orientalis are appended in this bulletin together with two samples of wrapping papers from bamboo.
