  • Patent number: 4688370
    Abstract: The invention is a method and machine for filling and sealing a multiwall valve bag. The bag is fabricated with a valve structure that has at least two separated layers of a polymer composition capable of being heated by electromagnetic energy in the radio frequency range (RF energy). After the bag is filled with a product, the valve structure of the bag is clamped against a set of electrodes that are carrying the RF energy. In a very short time, the polymer layers in the valve structure will absorb enough of the RF energy to join together and thus "heat" seal the filled bag.
