| 摘 要： | INTRODUCTIONThe developments of environmentally friendly polymeric are classified into two categories: the degradable synthetic polymers (PCL 1- 2], PLA and PVA 3], etc.) and the renewable natural polymers (chitin, pectin, cellulose 4-7] and starch 8], etc.) Among these, starch has been considered for many years as a polymer with a high potential for packaging application because of low cost, renewability and biodegradability. It usually has two major components and appears as a mi…

| Abstract: | Native corn starch and hydroxypropyl starch (HPS) based plastic films were prepared using the short pulp fiber as reinforcement and the glycerol as the plasticizer. The results of tensile test showed that the tensile strength and the elongation at break increased with the pulp contents. With the glycerol contents, the elongation at break increased considerably, but the tensile strength decreased. The water uptake of the films decreased with the pulp contents and hydroxypropylation, but increased with the glycerol contents. So it is concluded that the films was reinforced by pulp fiber and hydroxypropylation. |
