Self-opening plastic bag pack system

摘要

A self-opening pack of plastic bags for use with a bagging rack. The pack of plastic bags is formed of plastic material which has been exposed to corona surface treatment. 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. A central tab portion is located on the front and rear walls in 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 tearing cut 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. Frangible pressure bonding is found along both sides of said tearing cut. Frangible pressure bonds are also formed on inner handle edges or edges of apertures or flaps formed in the stack of handles. 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.
