Our Products conform to Quality Manage Syetem Stand:ISO9001---2000 YQZB-16A double-sheet ultrasonic paper cup making machine supplement the YQZB-16 automatic paper cup machine?limit. YQZB-16A double-sheet ultrasonic paper cup making machine have been designed to making two-side PE coated paper cups. In order to sealing the double coated paper cup body, we install the ultrasonic parts instead heater to seal the paper cup-fan-wall body. For the double PE coated paper mean the two side of the paper are coated, when a heater applied on the outside surface of the paper cups, the PE film will be burnt and become yellowish or blackish color and make the paper cups shape in ugly. Of cause the ultrasonic paper cup machine can seal one side PE coated paper cups, but if you really do this, the ultrasonic sealing head will soon breakdown, so we recommend you add a extra heater head to sealing the one-side PE coated paper cups.
