DS-B12 Double PE coated Paper Cup Forming Machine is development equipment on DS-A12 single side PE coated paper cup machine.
In this type paper cup machine, we add a ultrasonic system to sealing the paper cup body, the ultrasonic system resolve the problem that double sides PE coated paper can not be sealing by heater, the reason is that when a heater is adopted on the outside surface the PE film will be burnt and become yellow or blackish and make the cups shape in ugly. Then in this type machine you can produce both double sides PE coated paper cups and single side PE coated paper cups only exchanging the raw material.
