Methods of making a woven laminated plastic bag having an easy open feature are provided. The easy open feature is generally defined by a weakened portion in the bag, such as formed by cutting, punching, or using a laser to provide a plurality of cuts and/or perforations in the bag. In various aspects the bag can be fabricated from a woven polypropylene and/or polyethylene layer, which can be laminated with a film layer, can form a pinch bottom bag, and can have one or both sides include graphics and/or printing. The bag can also be sealed to be sealed to provide a top end and/or a bottom end either or both of which provide a discrete area which may contain discrete graphics and/or printing.
