Effect of coating paper using chitosan and modified polylactic acid

This study was carried out to determine the effect coating with polylactic acid-chitosan complex on the packaging paper by two methods of mixing and grafting. For this purpose, handsheet (80 g/m2) was made using long fibers collected from Mazandaran Wood and Paper Factory. Poly lactic acid, chitosa...

For this purpose, handsheet (80 g/m2) was made using long fibers collected from Mazandaran Wood and Paper Factory.

In the grafting method, by chemical modification of chitosan and polylactic acid, 0.01 g of EDC (N-(3-dimethy laminopropyl)-N/-ethylcarbodiimide hydrochloride), 0.1 g of Span 80 and 0.047 g of HOBT ( 1- Hydoxy benzotriazole) homogeneous solution were prepared and applied on a paper surface.
