Abstract
Abstract A method is provided for enhancing yield of a cook-in packaged food product that includes first providing an adhering cook-in package comprising a flexible plastic container being substantially conformable to a selected food product and having an inner surface of polymeric olefin having been subjected to an adhering surface treatment in the presence of oxygen, then conforming said package about a selected food product and cooking the packaged product, whereupon said inner package surface adheres to said food product to substantially prevent cook-out of fluids therefrom.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
110 words
A method for enhancing yield of cook-in packaged meat product, comprising: (a) providing an adhering cook-in package comprising a flexible plastic container being substantially conformable to a selected meat product and having an inner meat product contacting surface of polymeric olefin having been subjected to an energetic radiation surface treatment in the presence of oxygen sufficient to cause said inner surface to adhere to the meat product during cook-in, said container having been formed from hot blown tubular film; (b) conforming said package about a selected meat product; and (c) cooking the packaged product, whereupon said inner surface adheres to said meat product to substantially prevent cook-out of fluids therefrom.
Claim 2
Independent Claim
110 words
A method for enhancing yield of cook-in packaged meat product, comprising: (a) providing an adhering cook-in package comprising a flexible plastic container being substantially conformable to a selected meat product and having an inner meat product contacting surface of polymeric olefin having been subjected to an energetic radiation surface treatment in the presence of oxygen sufficient to cause said inner surface to adhere to the meat product during cook-in, said container having been formed from hot blown tubular film; (b) conforming said package about a selected meat product; and (c) cooking the packaged product, whereupon said inner surface adheres to said meat product to substantially prevent cook-out of fluids therefrom.
Claim 3
Dependent Claim
13 words
The method of claim 1 wherein said inner surface is oxidized polymeric olefin.
Claim 4
Dependent Claim
18 words
The method of claim 1 wherein said container is a tubular casing and said conforming is by stuffing.
Claim 5
Dependent Claim
25 words
The method of claim 1 wherein said container is a heat shrinkable bag and said conforming is by container shrinkage upon initiation of said cooking.
Claim 6
Dependent Claim
18 words
The method of claim 1 wherein the interior surface of said tubular film forms said inner container surface.
Claim 7
Dependent Claim
18 words
The method of claim 5 wherein said tubular film has been laid open prior to said surface treatment.
Claim 8
Dependent Claim
30 words
The method of claim 5 wherein said surface treatment has been conducted on said tubular film while flushing the interior of said tubular film to maintain an oxidative atmosphere therein.
Claim 9
Dependent Claim
30 words
The method of claim 1 wherein the exterior surface of said tubular film forms said inner container surface and said tubular film has been laid open after said surface treatment.
Claim 10
Dependent Claim
23 words
The method of claim 1, 5, 6, 7 or 8 wherein said film is irradiatively cross-linked while maintaining said surface under oxidative conditions.
Claim 11
Dependent Claim
19 words
The method of claim 9 wherein said inner surface is polyethylene irradiated to a dosage of about 8-10 megarads.
Claim 12
Independent Claim
109 words
A method for enhancing yield of a cook-in packaged meat product, comprising: (a) providing an adhering cook-in package comprising a flexible plastic container being substantially conformable to a selected meat product and having a single ply structure of hot blown, nonoriented polyethylene, said single ply including a meat product contacting surface having been irradiatively cross-linked in the presence of oxygen sufficient to cause said meat product contacting surface to adhere to the meat product during cook-in; (b) conforming said package about a selected meat product; and (c) cooking the packaged product, whereupon said meat product contacting surface adheres to said meat product to substantially prevent cook-out of fluids therefrom.
Claim 13
Independent Claim
