Carton Plast PP Corrugated Sheet is widely used in packaging industry nowadays. Because it is light and very strong compared to paper corrugated sheets. In box Production cartonplast is used and it is cut by lazer, folded by heat and at the last stage it should be sealed to itself. In that point, there are 2 ways; one is heat and the other is Ultrasonic. Heat sealing damages the material and the looking is not very nice so instead of heating, Ultrasonic sealing is preferred. Sonikel ultrasonics, designs and manufactures Ultrasonic sealing machine for cartonplast pp corrugated sheets. Edge sealer is also preferred to close the corrugated free spaces on the top of the box. If not closed, the filling product can go through from these free spaces so Sonikel designs and manufactures customized Ultrasonic welding stations.
