Characteristics of mixing biodegradable polymers and polymer impregnated paper for mulching mat for seedling were investigated. The mixed film of 70% PLA was most easily biodegradable. The surface of polymer films were changed to more rough due to enzymatic degradation of lipase. Tensile strength an

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%, res

Mulching technique is used to control the temperature and moisture content of soil by covering the ground surface. Most kinds of mulching film are made of polyethylene which is non-biodegradable synthetic polymer. Utilizing these films has been one of the main sources in soil pollution. Thus residua
