热压封合
Hot pressing sealing
在滚筒式铝塑泡罩包装的热压封合过程中，ＰＶＣ带与铝箔是由相互平行的滚筒状热封辊和网纹辊在一定温度和压力作用下作啮合式对滚来完成热压封合的。热封辊和网纹辊的接触为线性接触，所需要的压力相对较小。
In the process of hot-pressing sealing of drum-type aluminium-plastic foam cover packaging, the hot-pressing sealing of PVC strip and aluminium foil is accomplished by intermeshing drum-shaped hot-sealing roll and reticulated roll under certain temperature and pressure. The contact between the heat sealing roll and the reticulated roll is linear, and the pressure required is relatively small.
在平板式铝塑泡罩包装的热压封合过程中，ＰＶＣ带与铝箔是由相互平行的平板状热封板和网纹板在一定温度和压力作用下在同一平面内来完成热压封合的。热封板和网纹板的接触为面状接触，所需要的压力相对较大。
In the process of hot-pressing sealing of flat aluminium-plastic blister packaging, PVC strip and aluminium foil are sealed by parallel flat heat sealing plate and reticulated plate in the same plane under certain temperature and pressure. The contact between the heat sealing plate and the reticulated plate is planar, and the pressure required is relatively large.
