Patent ID: 7772139

Claim:
A Gas Permeable Film, consisting of a. a non-woven fabric substrate, the substrate adapted for transmission of gases; b. a polymer coating on the non-woven fabric substrate, the polymer coating having a thickness between 0.18 MIL-2.0 MIL, the thickness dependent upon a type of a produce item, the produce item responsive to a created atmosphere resulting from the polymer coating, and the weight of the produce items; i. the polymer coating having an oxygen permeability of at least 55,000 cc/100 in2/day/atm, with a maximum permeability of 611,111 cc/mil/100 in2/day/atm at 13° C.; and ii. the polymer coating having a carbon dioxide permeability of at least 350,000 cc/100 in2/day/atm, with a maximum permeability of 3,888,889 cc/100 in2/day/atm at 13° C.
