Abstract

This study demonstrates the potential of Eucheuma denticulatum N. L. Burman Collins et Harvey for papermaking by determining the effect of increasing the amount of the seaweed gel in Bambusa blumeana J. A.Schultes handsheet on selected properties of packaging paper. Dried Eucheuma (43.84% carrageenan yield) was soaked and boiled in water to extract the carrageenan and produce a seaweed gel, which was completely utilized without discarding either the cellulosic solid residue or the dissolved carrageenan.In preliminary tests, tray drying of pure seaweed gel forms a thin handmade sheet, while adding bamboo pulp produced a more stable sheet. Handsheets were formed and the Canadian Standard a freeness is satisfactory if the seaweed gel was added to the unbleached bamboo soda pulp several minutes before disintegration. physical testing of pulp handsheets based on TAPPI standards was conducted and was compared to values given by Bureau of Product Standards. Tear index increases with increasing amount of seaweed, and it met the standard values. Burst and tensile indices reach an interpolated relative maxima at 5.5% and 9.2% respectively, but the indices are below standards. Brightness is highest at the 85 pulp blend with the strongest recorded physical strength but lowest thickness. It was concluded that using seaweed gel is economical but it needs to have sufficient fibers to bind with for it to be effective. Bleaching the bamboo pulp or utilizing other pulp materials is recommended to increase physical properties of the handsheets.
