Product Description
The PVC Bag Sealing Automatic High Frequency Welding Machine belongs to the high-frequency equipment designed for automatic PVC bag production from film rolls. By utilizing an electronic oscillation tube, the machine produces high-frequency electromagnetic fields. Processing PVC film between the upper and lower electrodes in an automatic motorized roll material feeding system, it exerts a precise process of cutting, welding, and edge trimming.
Technology Principle: The internal friction molecules generate heat through polarization and mutual movement under the HF/RF electromagnetic field. Under mold pressure, a seamless welding bond is achieved. Due to the localized heating and pressure, the resulting PVC bags offer exceptional tear resistance and a clean appearance.
