In this study, heat transfer in a heat sealing process was simulated using COMSOL Multiphysics software. Variations of thermal conductivity, specific heat, and density of polymers with temperature were measured in a wide temperature range. The temperature profile at the interface between two sealing films was measured using a fine thermocouple. Comparing experimental and simulation results indicated the high accuracy of the simulation and the significant role of considering thermal contact resistance as the boundary condition between the jaws and films. These results showed that the present simulation, for the first time, can successfully predict heat transfer and interface temperature in a heat sealing process without any fitting parameter. Moreover, the obtained results showed that the simulation can predict the effect of jaw temperature, sealing time, film thickness, and polymer crystallinity in a wide range of temperatures from below melting point to much higher temperatures than the melting point of the sealant.

多层聚合物薄膜热封中传热的模拟：工艺参数和材料性能的影响

在这项研究中，使用COMSOL Multiphysics软件模拟了热封过程中的热传递。在较宽的温度范围内测量了热导率，比热和聚合物密度随温度的变化。使用精细热电偶测量两个密封膜之间的界面处的温度曲线。比较实验结果和仿真结果表明，仿真具有很高的准确性，并且考虑到将热接触电阻视为钳口和薄膜之间的边界条件，该方法具有重要作用。这些结果表明，本仿真首次可以在没有任何拟合参数的情况下成功地预测热封过程中的传热和界面温度。此外，获得的结果表明，该模拟可以预测颌骨温度的影响，
