Nalika ketebalan sakaadesif layer has a certain relationship with the adesif force, the greater the adesif force of the hot melt adesif, the greater the adesif force, while the adesif layer is too thin or even has only one adesif surface, the greater the adesif force , And when the adesif layer is too thin or even has only one adesif surface, the adesif force will be smaller.

     If the adesif layer is too thick, the probability of defects in the adesif layer will increase. When external forces are applied, stress concentration will easily occur around these defects, and the hot melt adesif layer will break. The proper thickness of the hot melt adesif can make the two surfaces of the adherend fully wet, so that the adesif layer can form a complete adesif layer between the two adherends.
