ABSTRACT:
A pack of self-opening plastic T-shirt bags for use with a bagging rack. Each plastic bag in the pack of bags has a mouth tab portion between its two upwardly extending handles, which are at the sides of the mouth of the T-shirt bags. The mouth tab portion is located on the front and rear walls in the mouth region of the plastic bags. The mouth tab portion has an aperture for receiving a retaining projection of a bagging rack. Frangible pressure bonding is formed along the perimeter of said mouth aperture. Flapless handle apertures are also formed in the handles, with frangible pressure bonds formed along their perimeter edges. Due to the frangible bonding formed between adjacent bags, as a frontmost bag is removed from the pack of bags on the bagging rack, the next bag in the pack of bags will automatically self-open into a open position for loading with merchandise. The frangible bonding is formed with dies having a die portion with a cutting edge and having a compression portion, with a generally blunt leading edge, positioned in close proximity to the die portion.
