Abstract
In general, the instant invention relates to protein adhesion cook-in films (1) having a protein adhesion sealing layer of polymer having carboxylic acid moieties and (2) wherein said sealing layer does not require metal ionomer cross-linking in order to exhibit protein adhesion. More particularly, it relates to a thermoplastic film comprising a thermosealing layer selected from ethylene-methacrylic acid copolymers ( EMAA ) having a methacrylic acid content of about 4 to about 18% by weight, and ethylene-acrylic acid copolymers ( EAA ) having an acrylic acid content of about 4 to about 22% by weight. The sealing layer has improved sealing and strength properties, as well as protein adhesion characteristics.
