The heavy-duty insulation removal vacuum bags are made of 100% polypropylene fabric (4.3 oz. strength). 130% stronger than the industry standard. Guaranteed not to rip! The fabric allows the bag to breathe when insulation is disposed into the expandable bag when vacuuming out from an attic. These insulation vacuum bags use a strong polypropylene fabric and durable polypropylene stitching. With this insulation vacuum bag you will be able to fit approximately 75 cubic feet of insulation or 300 lbs.
