This paper examines the effects of chitosan, starch, and polyvinyl
alcohol (PVA) to improve the surface properties of cellulose-based paper obtained from
local raw materials. The polymers are incorporated into the paper polythene by
spraying. The results showed that the addition of chitosan to paper polythene, which is
made of cellulose fibers, has an improvement in surface properties compared to the
effect of other additives. The degree of exposure of starch coincided with the degree of
exposure of chitosan, but it resulted in a decrease in the water absorption potential of
the paper compared to chitosan at the same concentration. In many other properties,
especially the most important feature for printing paper, surface smoothness, chitosanaffected
papers are superior to starch or PVA-affected paper
