ABSTRACT:
A method for manufacturing automatic consecutively opened thermoplastic T-shirt bags for dispensing from a conventional supporting rack. The method involves providing a continuous flattened tube of thermoplastic film and applying adhesive solution using a printing press to form adhesion regions on the outside of the tube. The adhesive solution can be applied using a flexo or gravure printing process. The method then involves forming side gussets in the tube and making traverse seals in the tube, thereby dividing the tube into pillowcases. The pillowcases are separated at the seals to form a series of end-sealed gussetted pillowcases which are stacked to form a bag pack. Next, the bag pack is cut along a bag-mouth contour to from a plurality of T-shirt bags. The bag-mouth contour forms a set of laterally spaced handles each having a receiving aperture for a conventional support rod of a dispensing rack, a central tab having a mounting aperture, and an open mouth region. The adhesion regions are optimally located below the receiving apertures and above the lowest point of the bag-mouth contour. Finally, slight pressure is applied to the proximate area of the adhesion regions of each bag in the bag pack to form a disengageable link between consecutive bags. The invention also relates to the T-shirt bags and the bag packs produced from this method.
