a system for suspending a pack of thermoplastic bags , loading bags , removing loaded bags and for automatically opening the next bag preparatory to loading it by having a pack of handled bags suspended from laterally spaced elongated rods of a rack . the bags have been corona discharge treated to such an extent that the application of pressure will cause adjacently facing regions to releasably adhere together until a moderate force separates them . during removal of a bag front the bag pack at least a portion of the front wall of the next bag will follow the bag being removed for a short distance before separation thereby opening said next bag rendering it ready for loading . an improved means for applying the requisite pressure is disclosed herein .
