The purpose of this study is to evaluate the physical and mechanical properties of papers made of tree branches as a cellulose source. The branches of the tree Platanus orientalis plain region of Astara and the Kraft pulping process used. For the process of chemical baking soda in varying levels 10, 14, 16, 18 and 20 percent based on the dry weight of plantain wood chips were used. Also the cooking time considered in three levels of 60, 80 and 100 minutes. Cooking temperature and the cooking sulfidity in all cases remained at a constant level of 165 degrees Celsius and 25 percent, respectively and Liquor ratio plantain chips are based on standard laboratory Digester 8 to 1. Also to make handmade paper, pulp freeness were refined to reach about 25 ± 350 ml. 60 grams handmade paper were prepared of refined pulps and it’ s Resistance and mechanical properties were measured. Statistical analysis of features of handmade paper based on completely randomized design factorial test, and strength features of handmade paper of the ANOVA and Duncan's test was used to compare the average. Strength properties of the produced kraft pulp by the bursting index, tensile index, folding index, rupture index and brightness, were 55/5(Kpa cm2/g), 10082(Nm/g), 55(n), 53/6(mNm2/g) and 32/53(percent), respectively.
