Easy dispense T-shirt bags

A method for forming a bag pack comprising a plurality of easy open handle bags, the method comprising the steps of:

• (a) forming an elongated, flattened tube, the tube having an external surface and an internal surface;
• (b) removing static from the tube;
• (c) after step (b), treating at least a portion of the external surface of the tube with a corona discharge with about 0.5 to about 5 watt minutes per square foot treated;
• (d) cutting and sealing the tube to form a series of individual bags, wherein each individual bag of the series of bags has a front panel with respective exterior and interior surfaces and a back panel with respective exterior and interior surfaces;
• (e) inducing an alternating static charge on the series of bags by inducing a first charge on said respective exterior and interior surfaces of both the front and back panels of a first individual bag and by inducing a second charge on said respective exterior and interior surfaces of both the front and back panels of a second individual bag adjacent to said first individual bag, so that at least a portion of each bag is charged, with adjacent bags being at different polarities and said front and rear panels of said individual bags are at the same polarity, thereby forming a series of alternatively charged bags;
• (f) stacking the series of alternatively charged bags into a pack 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 from and back panels of each individual bag repel each other so the bags are easy to open;
• (g) die cutting the stacked series of bags into the shape of handle bags;
• and
• (h) cold welding the exterior surfaces of the handle bags in the stack together at selected spots, with a force of from about 50,000 to 90,000 psi,
• wherein the power of the corona discharge and the force of the pressure weld are such that (i) the interior surfaces of the handle bags are not welded together, (ii) when a handle bag is pulled torn the pack, the adjacent next bag in the pack is at least partly opened, and (iii) when a handle bag is pulled from the stack, the adjacent next bag is not torn at the selected spots.

A method for forming a bag pack comprising a plurality of easy open bags from an elongated, flattened tube, the method comprising the steps of:

• (a) forming a series of individual bags from the tube, wherein each individual bag of the series of bags has a front panel with respective exterior and interior surfaces and a back panel with respective exterior and interior surfaces;
• (b) removing static from the bags with a static eliminator;
• (c) inducing an alternating static charge on the series of bags by inducing a first charge on said respective exterior and interior surfaces of both the front and back panels of a first individual bag and by inducing a second charge on said respective exterior and interior surfaces of both the front and back panels of a second individual bag adjacent to said first individual bag, so that at least a portion of each bag is charged, with adjacent bags being at different polarities and said from and rear panels of said individual bags are at the same polarity, thereby forming a series of alternatively charged bags;
• (d) stacking the series of alternatively charged bags into a pack 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 from and back panels of each individual bag repel each other so the bags are easy to open.
