摘要
采用拉伸实验,研究形变速率对聚丙烯包装薄膜屈服强度和断裂强度的影响,同时研究在80℃条件下热氧老化处理聚丙烯包装薄膜后,老化时间对材料屈服强度和弹性模量的影响。
The effects of oxygen and thermal degradation and deforming velocity on the tensile properties of the polypropylene film for packaging are studied through the mechanical tensile test.At the same time, the effects of ageing time on the yield strength and elastic modulus are discussed.
