摘　　要：软包装袋大多采用棒式热封合，主要是通过对加热棒温度、热封时间、加热棒与硅胶板之间压力三者进行协调。最终达到满意的封合效果。本文详细分析了软包装制袋工序中三大决定性的质量要素：热封温度、热封时间和热封压力，是如何影响热封效果的，并就制袋时容易出现的裁切线不整齐、热封强度差、热封后袋子翘曲、热封强度不良、热封部位产生气泡或表面不平、滑爽性不良、制袋长度及其相关偏差、袋子宽度出现偏差等给出了解决方法。Flexible packaging bags mostly use the rod type of heat sealing, mainly coordinate through the heating pipes temperature, heat sealing time and the pressure between heating rods and silica gel plate, finally reach the satisfactory sealing effect. This paper analyzes the three crucial quality elements in detail in flexible packaging bag making process： heat sealing temperature, heat sealing time and heat sealing pressure, and how they influence the effect of heat sealing, and gives the solution of the problems that commonly appears such as bag cutting tangent untidy, poor heat sealing strength, bag warping after heat sealing, poor heat sealing strength, bubbles or surface uneven in heat sealing parts, bad bag slide, bag length deviation and relative deviation, width deviation etc.
