AIR PACKING MACHINE AND METHOD USING ULTRASONIC SEALING

摘要

An apparatus (10) for manufacturing inflatable packaging pillows (24) having agas dispenser (14) for dispensing a gas within a partially sealed inflatable pouch and an ultrasonic welding assembly (16) comprised of a horn (48) and an anvil for sealing the pouch after inflation of the pouch. The apparatus includes a feeding mechanismfor advancing inflatable packing across the ultrasonic welding assembly. The horn preferably seals the pouch continuously without interruption of the advancement of the pouch. A method of manufacturing inflatable packaging including the steps of providing an apparatus for manufacturing inflatable packaging pillows, inflating a pillow, and sealing the pillow using ultrasonic energy. An ultrasonically sealable inflatable packing cushion made of a polymer film web (20) having two layers bonded together at a wall that defines an unsealed pocket. The packing cushion is readily weldable to itself at the unsealed portion of the pocket through the application of ultrasonic energy.
