Abstract
Utilization of banana plant for making hand made paper and certain grades of specialty paperboards have been
investigated. The physiochemical characteristics of the three species of banana plants viz. Musa velutina, M. paradisica
and M. sapientum available in NEregion of India were studied. The plants consists an average of 25 -27 %sheath, 42 -48
% core and 27 - 30 % leaves. The cellulose content was varied from 59 - 63 %, lignin from 15.3 - 18.2 %and pantosan
from 13.5 - 15.2 %. in all the three plant species. The cooking experiments were conducted in an open vat under pressure
free condition using NaOH and Na2C03 as cooking chemicals. The percentages of cooking chemicals were varied from 6-
10 %maintaining bath ratio at 1:6. The unbleached pulp yield was recorded 48 - 52 %. The bleaching of the pulps was
carried out using H- E- H202sequence to get 60 - 65 %brightness. The physical strength properties of hand made paper
made from these three plant species showed tensile index 55.4 - 62.8 Nmg-1,Tearindex 10.4 - 15.2 mNm2t, Burstindex
6.2 - 8.7 Kpm2g-1with Double fold values 300+. However certain specialty paperboard such as leatherboard made out of
banana pulp in combination 'with bamboo pulp showed breaking load 120 - 145 (Kg),Tensile strength (dry)220 - 250
Kg/cm2,elongation 39 - 42 %, linearshrinkage 4.0% and areashrinkage 4.2 - 4.5%. Another specialty boardssuch as solid
toughened board made from the blends of ragand banana pulp showed very good physical strength with breaking load
value 160 kg and 90 kg respectively for30 cm and 60cm span with minimum absorption of moisture.
