  • Patent number: 6286681
    Abstract: A ventilated plastic bag particularly adapted for carrying hot food from fast food restaurants includes the following components. Front and rear wall sections are connected together to define a closed bottom area and an open top area. A handle or handles are provided in the top area and include a cut out of the front and rear wall sections creating reduced strength regions with resulting high potential for carrying around at least part of the cut out. Closely spaced micro-perforations extend through the wall sections in at least a major portion of the plastic bag other than the reduced strength regions to provide ventilation to an interior food carrying area of the plastic bag while not further weakening the reduced strength regions and increasing the potential for tearing of the bag.
