Abstract
A wrapping material having three distinct polymeric layers interfaced with a woven polymeric scrim is disclosed. A first polymeric layer is formed by extruding a first polymeric coating onto the scrim. A second polymeric layer and a third polymeric layer are simultaneously formed by co-extruding a second polymeric coating onto the scrim and a third polymeric coating onto the second polymeric coating.
Claims22
A wrapping material comprising:
- a sheet comprising a plurality of first polymeric tapes and a plurality of second polymeric tapes, the first and second polymeric tapes being interwoven;
- a first polymeric coating applied to a first side of the sheet;
- a second polymeric coating applied to a second side of the sheet;
- and
- a third polymeric coating applied to the second polymeric coating,
- wherein the second polymeric coating forms a UV-blocking layer of the wrapping material, the UV-blocking layer operable to block UV light from passing through the UV-blocking layer;
- wherein the third polymeric coating forms a cover layer of the wrapping material;
- and
- wherein a combined thickness of the UV-blocking layer and the cover layer is in the range of 0.01 mm to 0.04 mm;
- and
- wherein the second polymeric coating and the third polymeric coating are co-extruded onto the second side of the sheet.

A method of manufacturing a wrapping material, the method comprising:
- providing a polymer feedstock;
- form first polymeric tapes from the feedstock;
- form second polymeric tapes from the feedstock;
- weaving the first polymeric tapes and the second polymeric tapes to form a polymeric scrim;
- applying a first polymeric coating to a first side of the polymeric scrim;
- and
- co-extruding a second polymeric coating to a second side of the polymeric scrim and a third polymeric coating to the second polymeric coating,
- wherein the second polymeric coating forms a UV-blocking layer of the wrapping material, the UV-blocking layer operable to block UV light from passing through the UV-blocking layer;
- wherein the third polymeric coating forms a cover layer of the wrapping material;
- and
- wherein a combined thickness of the UV-blocking layer and the cover layer is in the range of 0.01 mm to 0.04 mm.
