Patent Images
1. An inflatable multilayered polymeric film for covering an agricultural structure or greenhouse, the inflatable multilayered polymeric film comprising:
- at least one first layer comprising ethylene vinyl alcohol, andat least one second layer connected thereto, the at least one second layer comprising a polymeric material selected from the group consisting of polyethylene, polypropylene, ethylene vinyl acetate copolymer, ethylene butyl acrylate copolymer, thermoplastic polyurethane, and combinations thereof,wherein the at least one first layer and the at least one second layer are formed as a unitary structure having an average delamination strength of less than 250 g/15 mm when measured using ASTM D-1876,wherein the inflatable multilayered polymeric film is co-extruded, and wherein, when in use, a fluid is inserted between the at least one first layer and the at least one second layer.
