Abstract
A multilayer film is provided in the form of an extruded sheet for food wrapping and cooking procedures. The film is made up of alternating layers of a first generally ductile material and a second generally brittle material. Upon wrapping a food item or container, the film exhibits dead fold and/or twistability characteristics. In one embodiment, the materials of the film are chosen to have softening points above about 450 degrees F. so that the film can be used in conventional ovens.
