I have several rolls of 6 mil (commercial construction grade) poly / plastic that I used as covering material. All the rolls are 54" wide and are actually 333 yards (999 feet) long. They weight over 100 ponds each. The picture is the smaller 540 ' x 54" roll.

　　I also have smaller rolls - 540 feet x 54" wide, as well - $50 each.

　　This is the typical plastic / poly / PVC carried by the box stores and what I have called 6 mil poly for 20 years.
