Abstract
Characteristics of biodegradable polymers for mulching mat for seedling were investigated. The solvent solubility of polymers is highest in methylene chloride and chloroform. Tensile strength and breaking elongation of polymer dipped paper were increased to the 0.43-1.46 kN/m and the 0.03-0.26%, respectively. PLAs had showed lower glass transition temperature and melting point than those of polyester. As a result, PLA should be most suitable polymer for mulching mat manufacturing. After biodégradation of polymers by lipase, surface of polymers was change to more flat due to enzymatic degradation.
