摘要
PET/PE复合薄膜广泛应用于食品和药品包装,但在生产过程中存在热封质量不稳定的问题,为了探索PET/PE复合薄膜热封质量的影响因素,采用热封机对复合材料进行热封,并用拉伸实验对热封强度进行测试,比较分析了热封方向、热封温度、热封速度对热封质量的影响作用,总结得出了PET/PE复合薄膜的最佳热封工艺参数。
PET/PE composite film is widely used in food and drug packaging, but there is heat sealing quality unstable problem in the production process. Influencing factors of heat sealing quality of PET/PE composite film were studied through heat sealing and tensile test. The influences of heat sealing direction, heat sealing temperature, and heat sealing speed on heat sealing quality were compared and analyzed. The optimal heat-seal processing parameters of PET/PE composite film were summarized.
