发明名称 LEICHT ZU ÖFFNENDER, FLEXIBLER PLASTIKBEUTEL
摘要 An easy opening plastic bag includes a plastic front panel, a plastic rear panel, and plastic left and right end panels coupled to the front and rear panels. A plastic gusset is formed at the top of the bag and is joined to the front, rear, left, and right panels. A first frangible portion is disposed near a top of the front panel, and a second frangible portion is disposed near a top of the rear panel. The first and second frangible portions lie in a plane which allows a portion of the bag to rotate away from the remainder of the bag about an axis parallel to the plane. A third frangible portion is provided in the bag and extends substantially perpendicular to the plane of the first and second frangible portions.
