ABSTRACT:
Dual-section ultra-thin (0.1-0.8 mil) plastic produce bags having a large upper compartment with an open top boundary (fill opening) and a bottom boundary that is partially open to a smaller lower section. The bags are provided in a series on a roll enabling dispensing of each bag by unrolling and tearing along a line of perforations. Individual plastic bags are defined by lines of adjacent heat seals and perforations on a flattened plastic tube. Two elongated side straps have ends attached to the bag adjacent to the top opening so that the top opening of the bag may be closed by tying the straps together. The straps are generally trapezoidal in shape with the widest dimension of the trapezoid being 50-60% the width of the bag at the junction line of the strap to the bag. This design provides strength to the attachment of the strap to the bag in order that the straps may also be used as a handle for carrying the bag. The width of the strap at its smallest dimension is at least as large as the human thumb length and 40-50% the bag width in order to facilitate opening the bag. The lower section is from 10-40% the volume of the upper main bag section. The dual section design permits placing smaller produce items, or a very few larger ones in the lower section alone, or loading larger produce items in the upper section.
