Cellulose-based biodegradable cushioning packaging material

In recent years, with the requirements of environmental protection of packaging materials improve, biodegradable materials more and more attention to. This paper to waste as raw materials, and by the synthesis of the biodegradable packaging material performance for research. The results show that: to recycle waste as raw material, add natural renewable material alkali lignin and cellulose, and influence factors of sheet material performance, get the film material performance is the ideal process parameters. According to People's Republic of China national standard GB/T6342-92 "plastic compression performance test method" and GB/T20197-2006 "degradable plastics the definition, classification, signs and degrade the performance requirements," as determined by the experimental method for testing. The orthogonal experiment results show that waste polyurethane: alkali lignin: cellulose = 3:4:6 made materials when mechanical properties and degradation is better. Compressive strength for 340 KPa, biodegradable sex for 40.1%, have reached national standards.
