Patent ID: 8283024

Claim:
A corrosive gas resistant laminate, comprising: a laminate capable of wrapping and forming a closed space about a metal surface and preventing metal corrosive gases comprising H 2 S, SO 2 , and halogen gases from corroding said metal surface and wherein said laminate is not utilizable as a food wrap; said laminate comprising: at least one outer thermoplastic polymer layer; at least one corrosive gas resistant barrier layer; at least one first tie layer that is compatible with said outer layer and said barrier layer and is located between said outer polymer layer and said corrosive gas resistant barrier layer, at least one inner thermoplastic polymer layer; at least one second tie layer that is compatible with said barrier layer and said inner layer and is located between said barrier layer and said inner layer; wherein at least one of said tie layers, independently, comprises a polyacrylate or a polymethacrylate wherein the ester portion thereof has from 1 to about 12 carbon atoms, or a blend of said polyacrylate or said polymethacrylate with a polyolefin; a polyanhydride or a polymaleic anhydride; or a copolymer of said polyanhydride or said polymaleic anhydride with an olefin, with ethylvinylacetate, or with ethylene acrylate; wherein said laminate has an H 2 S transmission rate of less than about 200 cc/100 m 2 /day, and including at least one VCI compound in said outer layer, or in said inner layer, or both, and wherein said VCI is capable of evaporating and filling said closed space.
