Apparatus and method for forming aperture cutouts for a pack of self-opening plastic bags

摘要

An apparatus, method, and pack of tabless, self-opening bags with flapless aperture cutouts pack. In the apparatus and method, cylindrical dies connected to a vacuum source are used to cut out plugs of holes, and the plugs are evacuated to a receptacle. Compression bars, or a relatively shallow bevel cut on the cylindrical die, are used to form area of frangible bonding in the central tab portion of the bag pack. The pack of tabless, self-opening bags with flapless aperture cutouts has no flap portions which might inadvertently detach from bag pack.
