生物降解地膜新材料的发展及产业化前景

Development and industrial prospect of new biodegradable film materials

地膜是我国农业生产中重要的物质生产资料之一,其广泛应用促进了农业生产方式的改变,提高了农业生产力,但同时地膜残留也带来严重的"白色污染"。近年来,由于降解新材料与加工工艺的不断创新,降解地膜得到了快速发展。就生物降解地膜出现的背景、发展过程、应用现状、面临的问题及其产业化前景进行了论述和分析。随着技术进步和环境问题的日益突出,生物降解地膜将成为21世纪农业新材料发展的重要领域。

Plastic fi lm has been one of the most important materials in agricultural production of China.The wideutilization of fi lm mulching has brought about the increase of agricultural production and the change of productionmodes,however,film residues have also given rise to serious“white pollution”.In recent years,continuousinnovation of degradable materials and processing technology have led to the fast development of degradable fi lm.In this paper,the background,development process,application status,problems and industrialization prospects ofbiodegradable plastic fi lm are discussed and analyzed.With the technological progress and increasing environmentalconcerns,biodegradable fi lm will become an important fi eld of new agricultural material in the21st century.
