Our 3 mil gusseted poly bags are manufactured with a tubular construction and a durable bottom seal. These poly bags have a gusseted (expandable) sides or bottom, which allows for more fill able space when the bag is opened. Gusseted Poly bag dimensions are outside dimensions: width x depth x length. The width is measured across the opening of the bag; depth is the fully extended gusset; and length runs from the opening to the bottom. These gusseted poly bags must be heat sealed, taped or twist tied for closure.
