A� polyethylene� tarpaulin (\"polytarp\") is not a traditional fabric, but rather, a� laminate� 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. 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 lose strength and water resistance if exposed to sunlight.
