A bag pack comprises a plurality of easy open handle bags. The bags are easy to open because the exterior surfaces of the bags are cold-welded together so that when one bag is pulled from the pack, the adjacent next bag is at least partly open. The external surfaces of the bags are not welded to the internal surfaces of the bags during the pressure welding process, because the material that forms the external surface of the bag is treated with a corona discharge, which renders the external surface more susceptible to cold weldings. Optionally a static charge is induced on the bags so that each bag is at a different voltage than the adjacent bags so the bags attract each other, and the panels of each individual bag repel each other, to contribute to the easy open feature.
A bag pack comprising a plurality of bags stacked in a pack, the bags each having a front panel with respective exterior and interior surfaces and a back panel with respective exterior and interior surfaces, the respective exterior and interior surfaces of both the front and back panels of a first individual bag having a first charge, the respective exterior and interior surfaces of both the front and back panels of a second individual bag adjacent to the first bag having a second charge, so that at least a portion of each bag is charged, the adjacent bags being at different polarities and the front and rear panels of the individual bags being at the same polarity, such that adjacent exterior surfaces of respective front and back panels of each adjacently stacked bag attract each other and the interior surfaces of respective front and back panels of each individual bag repel each other so the bags are easy to open.
A bag pack comprising a plurality of handle bags stacked in a pack, the handle bags each having a front panel with respective exterior and interior surfaces and a back panel with respective exterior and interior surfaces, the respective exterior and interior surfaces of both the front and back panels of a first individual handle bag having a first charge, the respective exterior and interior surfaces of both the front and back panels of a second individual bag adjacent to the first handle bag having a second charge, so that at least a portion of each handle bag is charged, the adjacent handle bags being at different polarities and the front and rear panels of the individual handle bags being at the same polarity, the adjacent exterior surfaces of respective front and back panels of each adjacently stacked handle bag are attached to each other by cold welds, such that adjacent exterior surfaces of respective front and back panels of each adjacently stacked handle bag attract each other and the interior surfaces of respective front and back panels of each individual handle bag repel each other so the handle bags are easy to open.
