5" x 9" 1.5 Mil Clear Flat Polyethylene Bag - 1,000/Case

The standard thickness for plastic bags is 2 - 3 mil. One "mil" refers to one thousandth of an inch. Bags that are thinner, such as bags with 1 mil, 1.25 mil, and 1.5 mil thicknesses, are better for single-use and disposable purposes. Bags that are thicker, including bags with a thickness of 4 mil and up, are considered hefty and are more reusable than thinner alternatives.
