Abstract
Abstract This invention relates to an improvement in a process for producing a cheese product wherein a cheese curd is extruded through a nozzle into a flexible, tubular mold, solidified to form a cheese product, and then removed from the flexible mold and the resulting product. The improvement is the use in the process of a "duplex type" mold constructed of An outer film laminate comprising a first film ply of cellophane having bonded to its outer surface a gas impermeable film having a gas transmission rate of less than about 10 cc/100 in. 2 /24 hour-atm.; A second film ply of biaxially oriented polypropylene bonded to the inner surface of said cellophane; and An inner film comprising a film ply of biaxially oriented polypropylene.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
123 words
In a process for producing a cheese product wherein a cheese curd is extruded through a nozzle into a flexible tubular mold, permitted to solidify or knit, and then removed from the mold to form a cheese product, the improvement which comprises: employing as said mold, a flexible tubular mold having (a) an outer film comprised of a laminate of a first film ply of cellophane having bonded to its outer surface a second film ply having a gas transmission rate of less than 10 cc/100 in. 2 /24 hour-atm. and a third film ply of biaxially oriented polypropylene bonded to the inner surface of the cellophane ply, and (b) an inner film comprised of a fourth film ply of biaxially oriented polypropylene.
Claim 2
Dependent Claim

In a process for producing a cheese product wherein a cheese curd is extruded through a nozzle into a flexible tubular mold, permitted to solidify or knit, and then removed from the mold to form a cheese product, the improvement which comprises: employing as said mold, a flexible tubular mold having (a) an outer film comprised of a laminate of a first film ply of cellophane having bonded to its outer surface a second film ply having a gas transmission rate of less than 10 cc/100 in. 2 /24 hour-atm. and a third film ply of biaxially oriented polypropylene bonded to the inner surface of the cellophane ply, and (b) an inner film comprised of a fourth film ply of biaxially oriented polypropylene.
Claim 3
Dependent Claim
47 words
The process of claim 1 wherein the inner film of biaxially oriented polypropylene has fifth and sixth film plies bonded to its inner and outer surfaces each of the fifth and sixth film plies having a gas transmission rate of less than 10cc/100 in. 2 /24 hour-atm.
Claim 4
Dependent Claim
24 words
The process of claim 2 wherein the films bonded to the cellophane ply and to the biaxially oriented polypropylene film plies are saran films.
Claim 5
Dependent Claim
60 words
The process of claim 1 wherein the cellophane ply of the outer film laminate has bonded thereto a film having a gas transmission rate of less than 10cc/100 in. 2 /24 hour-atm. intermediate the inner surface of the cellophane ply and the third biaxially oriented polypropylene film ply as well as to the outer surface of the third film ply.
Claim 6
Dependent Claim
32 words
The process of claim 1 wherein the edges of the outer film and the inner film are joined together to form a seam extending longitudinally along the surface of the tubular mold.
Claim 7
Dependent Claim
13 words
The process of claim 1 wherein the seam is formed by heat sealing.
Claim 8
Dependent Claim
31 words
The process of claim 6 wherein said seam is formed by disposing an edge of said outer film and inner film between the opposite edges of said outer and inner films.
Claim 9
Dependent Claim
23 words
The process of claim 1 wherein the saran film bonded to the outer surface of the cellophane ply has a release agent thereon.
