摘要
淀粉基聚乙烯醇生物降解塑料具有保持土壤表面温度、湿度，阻止杂草生长，降低外界环境对农作物的影响以及减少环境污染等优点．本文详细分析了影响淀粉塑料的拉伸强度、延伸率的几种主要因素，得出了它们的影响性能曲线，为生物降解塑料的推广使用提供了基础．
Biodegradable starch-based poly-vinyl alcohol plastics that are of advantages for keeeping the surface temperature and humidity of soil,preventing weed growth,decreasing the environmental influences on the crops.The paper analyses several main factors of influences on strength and elongation of starchbased plastics in detail.On the basis of experiments,a series of characteristic curves have been obtained by analysing.This provides a basis for utilization and extension of biodegradable plastic.
