More About Poly: Woven Coated Polyethylene (WPE) is a textile formed by weaving plastic strips together on a loom by interlacing two or more threads at right angles, known as warp and weft. Woven fabrics stretch diagonally in the biased directions creating a more substantial fabric. WPE has extremely high tear and tensile strengths and offers longer UV life than average blown plastic films. This material is coated with a poly resin offered in various colors and thicknesses. WPE has a very high strength-to-weight ratio, which allows it to be fabricated into large one-piece covers capable of covering more than one acre with just one piece.  Availability: This item leaves our warehouse within 10 - 14 business days
