Biodegradable material of polyvinyl alcohol ( PVA ) / starch alloy project brief  
Biodegradable material of polyvinyl alcohol ( PVA ) / starch alloy project brief introduction

Plastic packaging materials of light weight, high strength, can be made adaptable multifunctional packaging materials of plastic packaging, so people are becoming more and more dependent. But plastic packaging material of a large number of disposable also have a large number of waste, because of the large amount of waste, recycling, scattered collection costs, and the materials which are mostly inert material, it is difficult to degradation in natural environment and other reasons, makes them on the environment caused by pollution and the destruction of the ecological balance continue to accumulate, the twenty-first Century has become a social and ecological nightmare. Therefore, to solve the natural degradation of plastic, the plastic into the virtuous circle of ecosystem for its release, natural and environmental destruction, as scientists and enterprise development.

Degradable plastics research and development can be traced back to the nineteen seventies, in the United States was carried out in light of studies on degradable plastic. Nineteen eighties and research and development of the starch filled" biodegradable"
