【Abstract】 The physical and mechanical properties of the starch-polyethylene biodegradable plastics film and general plastics film were researched. It was indicated that the degradable rate of the testing material was more than 20% in 20 or 30 days. The water-absorbed rate and the permeating rate were higher than general plastics PP and CPP. The mechanical properties can meet the using need. At the same time, the application prospect of the biodegradable plastics film in packaging field was analyzed.更多还原
