发明名称 Plastic bag pack system with novel handle apertures
摘要 A pack of plastic bags for use with a bagging rack. Each plastic bag in the pack of bags has a central tab portion between its two upwardly extending handles, which are at the sides of the mouth of the T-shirt bags. "J"-shaped slits are formed in the handles for carrying them on a bagging rack. A central tab portion is located on the front and rear walls above the mouth region of the plastic bags. The central tab portion has an aperture for receiving a retaining hook of a bagging rack, and a central tab slit which extends across the central tab portion, except for uncut portions near side edges of the central tab. The tearing cuts pass through the stack of bags and follow a non-straight path. The pack of plastic bags is preferably formed from plastic material which has been exposed to corona surface treatment. Frangible pressure bonding can be formed along the bottom side of said tearing cut to provide a self-opening feature. When the top bag is removed from the bagging rack, the next bag in the pack of bags will self-open into a open position for loading with merchandise.
