Patent ID: 6986921

Claim:
A high temperature food preparation film comprising: a blended monolayer thermoplastic elastomer film for use in high temperature cooking applications comprising: from about 10 to about 40 weight percent, based on the total weight of said blended monolayer thermoplastic film, of thermoplastic elastomer block copolymers; and from about 60 to about 90 weight percent, based on the total weight of said blended monolayer thermoplastic film, of non-elastic polyesters; said high temperature cooking applications occurring at from about 212 degrees Fahrenheit to about 400 degrees Fahrenheit; said blended monolayer thermoplastic elastomer film providing a water vapor barrier having a transmission coefficient of less than about 20 gms/100 in 2 /day, and an oxygen barrier coefficient of less than about 100 cc-mil/100 in 2 /day.
