Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
84 words
A method for labelling a package having contents at a temperature below 0° C. and a wrapping of ionomer film adjacent to the contents comprising cooling the package and its contents to a temperature below 0° C. heating a label having a label face and an ionomer adhesive layer to a temperature adequate to melt the ionomer adhesive layer contacting the ionomer adhesive layer of the heated label with the wrapping of the cooled package to fuse the ionomer adhesive layer with the wrapping.
Claim 2
Independent Claim
84 words
A method for labelling a package having contents at a temperature below 0° C. and a wrapping of ionomer film adjacent to the contents comprising cooling the package and its contents to a temperature below 0° C. heating a label having a label face and an ionomer adhesive layer to a temperature adequate to melt the ionomer adhesive layer contacting the ionomer adhesive layer of the heated label with the wrapping of the cooled package to fuse the ionomer adhesive layer with the wrapping.
Claim 3
Dependent Claim
20 words
The method of claim 1 wherein the contents of the package is at a temperature of less than -20° C.
Claim 4
Dependent Claim
62 words
The method of claim 2 wherein the label face is paper and wherein adhesion forces between the label and the wrapping of the labelled package are such when the label is pulled from the package while the package contents are at a temperature of about -30° C., there is fiber tear over at least 50% of the area of the label face.
Claim 5
Dependent Claim
27 words
The method of claim 1 wherein the label is heated to a temperature of about 30° to 100° C. above the softening temperature of the ionomer adhesive.

Claim 7
Dependent Claim
15 words
The method of claim 5 wherein the pressure is maintained for 0.5 to 10 seconds.
