A Polyethylene tarpaulin ("polytarp") is not a traditional fabric, but rather, a laminated of woven and sheet material. The center is loosely woven from strips of Polyethylene plastic, with sheets of the same material bonded to the surface. This creates a fabric-like material that resists stretching well in all directions and is waterproof. All these Virgin PE Tarpaulin Sheets are widely used for truck covers, transportation, agriculture, industrial, building, etc. The big feature for the tarpaulin is economic, practical, convenient and so on. Sheets can be either of low-density polyethylene (LDPE) or high-density polyethylene (HDPE). When treated against ultraviolet light, these tarpaulins can last for years exposed to the elements, but non- UV treated material will quickly become brittle and loose strength and water resistance if exposed to sunlight.
