摘　　要：目的对影响强生口腔护理产品Rembrandt软塑包装热封强度的因素进行研究。方法基于Ansys有限元方法分析内部气压大小对软塑管热封性能的影响。结果仿真结果表明,当管尾长度在44~54 mm之间,管身尺寸在65~70 mm之间,管壁厚度在0.4~0.5 mm之间时,软塑管的应变满足初始条件的要求;软塑包装的热封失效与材料的密度无关,随着弹性模量的增大,材料的最大应变值逐渐减小。结论要想获得理想的热封（良好的强度和外观）并满足生产效率,需要材料、结构、温度、压力、时间等多个方面共同作用。The work aims to research the factors that affect the heat sealing strength of the soft plastic packaging of Johnson oral care products Rembrandt. The effect of the amount of the internal pressure on the heat sealing performance of soft plastic tube was analyzed in the Ansys finite element method. The simulation results showed that when the tube end was 44 ~ 54 mm long, the tube body was 65 - 70 mm long and the tube wall was 0.4 ~ 0.5 mm thick, the strain of the soft plastic tube met the requirements of initial conditions; the heat sealing failure of the soft plastic packaging was irre- levant to the density of the materials. With the increase in the elasticity modulus, the maximum strain of the material would gradually decrease. In order to obtain ideal heat sealing （good strength and appearance） and meet the production efficiency, material, structure, temperature, pressure and time, etc. are required to work together.
