Abstract
A packaged food article includes a meat product and a thermoplastic, heat shrinkable film. The film includes a meat-contact layer that contains a polymer which includes mer units derived from a C2-C4 α-olefin. The film is sealed so as to form a bag which encloses the meat product. At least one of the seals defines an arc which includes at least four segments. Each of the segments has a radius of curvature which differs from the radius of curvature of any adjoining segment. When the packaged food article is subjected to a temperature of from about 50° C. up to about the Vicat softening point of the polymer of the meat-contact layer, the packaged food article takes the general shape of a poultry breast.

A method of forming a packaged, cooked food product comprising:
- enclosing a food product within a package comprising a thermoplastic, heat-shrinkable film having a total free shrink at 85° C. of at least about 2% and comprising an inside layer comprising a polymer comprising mer units derived from a C2-C4 α-olefin, said package having at least one seal which defines an arc, said arc comprising at least four segments, each of said segments having a radius of curvature differing from the radius of curvature of any adjoining segment;
- and
- subsequently heating the packaged food product to shrink the film and to cook said food product to form a packaged, cooked food product conforming to the shape of the package.
