随着现代农业生产技术的不断提高，加之高原地区特殊环境因素的影响，人们对于棚膜性能有了更高的要求，于是耐候棚膜应运而生。本文在介绍了几种常见聚烯烃棚膜基料性能的基础上，着重阐述了云南塑料厂所生产的高原耐候棚膜的性能。通过对比表明：兰耐候棚膜的拉伸强度≥21 MPa；断裂伸长率≥600%；直角撕裂强度≥70 kN/m；人工加速老化后纵向断裂伸长率≥400%，均优于国家标准，完全达到了高原地区对紫外线显著的阻隔作用，并且使用寿命长达4年之久。最后指出聚烯烃多功能棚膜研制将是今后的研究重点，更多功能型的棚膜也将逐步实现并不断完善。

With the development of modern agricultural production technology,the special effect of environmental factors in the plateau region requires high performance of greenhouse film,so the weather resistant greenhouse films have emerged. Based on the performance of several common polyolefin film base materials , this review summarized the plateau weathering performance of greenhouse films produced by Yunnan Plastics Factory. Tensile strength of weathering greenhouse film≥21 MPa;elongation at break≥600%;rectangular tear strength≥70 KN/m;artificial accelerated aging after longitudinal elongation≥400%,all better than the national standards,fully met the UV barrier effect in the plateau region,and service life was up to 4 years. Finally,polyolefin functional agricultural film development will be the future focus,more functional greenhouse films will also be gradually implemented and constantly improved.
