The present invention provides a multilayered polymeric film with a luminous transmittance greater than 30% when measured using ASTM-D 1003-92, for covering an agricultural structure or greenhouse, wherein the film contains adjacent layers that have an average delamination strength of less than 250 g/15 mm when measured using ASTM D-1876. More particularly, the film is thus separated into two or more film layers which are inflated with gas to provide thermal insulation. |
