探讨BOPP/CPP复合膜拉断力、断裂标称应变指标的制定

Discussion about the Establishment of BOPP/CPP Membrane Breaking Force and Fracture Strain

塑料薄膜的拉伸性能是非常重要的力学指标,而BOPP/CPP复合膜没有相应的检测标准来规定力学指标,需要制定企业标准.文章利用电子万能试验机对10种厚度的BOPP/CPP复合膜测量拉断力与断裂标称应变.通过试验数据分析,确定企标中拉断力和断裂标称应变参数指标.

Principal mechanical properties of plastic films include Breaking Force and Fracture Strain. There is no corresponding testing standard for BOPP/CPP composite membrane. The analyst is required to dictate the enterprise standards. By using the electronic universal testing machine, measure the breaking force and fracture strain of BOPP/ CPP membrane for lO kinds of thickness. Through analyzing the test data, determine the parameters of the breaking force and fracture strain in the enterprise standard.
