Patent ID: 8356459

Claim:
A method for forming a food packaging composite laminate comprising: providing a packaging film base layer having a first side and a second side and formed from polymeric materials; providing a heat sealable layer on the second side of the base layer; extrusion coating at least one layer of polymeric material onto the first side of the base layer to provide an extrusion coating thereon; providing a packaging film outer layer having a first side and a second side and formed from polymeric materials, wherein at least one of the outer layer first or second sides is capable of being printed thereon; providing selected printing information on at least a portion of at least one side of the outer layer; and thermally laminating the extrusion coating on the base layer to the outer layer using a combination of heat and pressure so as to form a composite laminate wherein the base layer and the outer layer are thermally laminated using a nip formed from at least two laminating rolls in rotating contact with one another applying a nip pressure of at least 50 psi, and wherein at least one of the laminating rolls is heated to a temperature of at least about 180° F., and wherein the composite laminate has a bond strength of at least about 300 grams per inch.
