Each of our Poly Bag chair covers are made of low density Polyethylene. This 90" X 45" 3 mil bag provides a protective barrier against moisture and vapors while showing the quality of the product inside the bag. Our Poly Bags can be customized in many ways. They can be packaged as a roll with perforations in between bags, and the roll shipped boxed or cradlepacked or individually folded, also called case packed. Bags can be made for FDA approval, or be made with special additives for low water vapor transmission rate, for electrostatic discharge control, for chemical resistance and/or puncture resistant.
