Abstract
Abstract A label forming laminate including a face sheet, a layer of pressure sensitive adhesive abutting on one surface of the face sheet, a paper backing layer, and a release layer between an inner face surface of the paper backing layer and the adhesive layer, the paper layer having one machine glazed surface and a clay containing coating on its glazed surface and having score lines formed in its second and outer face surface; the paper backing layer being relatively bulky and uncompressed and having embrittled fibers in its glazed surface.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
177 words
A laminate for use in making a label or the like and comprising a face sheet, a layer of pressure sensitive adhesive in contact with one surface of said face sheet, a fibrous paper backing layer, and a release layer between one face of said paper backing layer and one surface of said adhesive layer and where said lamainate is characterized by said paper layer having a clay containing coating on its said one face and having appreciably compacted score lines formed in its second and porous outer face, said one face of said paper backing layer having a machine glazed surface, said clay containing coating being relatively uniform and non-porous, said paper backing layer having a BEKK smoothness on its said coated one face of a minimum of about 360 and having a maximum BEKK smoothness on its uncoated face of about 30, said paper backing layer being uncompressed, and said paper backing layer of a given weight having more bulk per unit of basic weight than a super calendered paper of the same basic weight.
Claim 2
Dependent Claim
177 words
A laminate for use in making a label or the like and comprising a face sheet, a layer of pressure sensitive adhesive in contact with one surface of said face sheet, a fibrous paper backing layer, and a release layer between one face of said paper backing layer and one surface of said adhesive layer and where said lamainate is characterized by said paper layer having a clay containing coating on its said one face and having appreciably compacted score lines formed in its second and porous outer face, said one face of said paper backing layer having a machine glazed surface, said clay containing coating being relatively uniform and non-porous, said paper backing layer having a BEKK smoothness on its said coated one face of a minimum of about 360 and having a maximum BEKK smoothness on its uncoated face of about 30, said paper backing layer being uncompressed, and said paper backing layer of a given weight having more bulk per unit of basic weight than a super calendered paper of the same basic weight.
Claim 3
Dependent Claim
20 words
A laminate as in claim 1 where the paper layer has at least 10% more bulk than super calendered papers.
Claim 4
Dependent Claim
154 words
A laminate for use in making a label or the like and comprising a face sheet, a layer of pressure sensitive adhesive next to one surface of said face sheet, a fibrous paper backing layer and a release layer between one face surface paper backing layer and a release layer between one face surface of said paper backing layer and one surface of said adhesive layer and where said laminate is characterized by said paper layer having one machine glazed surface and a clay containing coating on its said glazed surface and having score lines formed in its second and outer face surface; said paper backing layer being relatively bulky, porous and uncompressed the paper in the paper layer at the score line being appreciably compacted to embrittlement, said paper backing layer of a given weight having more bulk per unit of basic weight than a super calendered paper of the same basic weight.
Claim 5
Dependent Claim
154 words
A laminate for use in making a label or the like and comprising a face sheet, a layer of pressure sensitive adhesive next to one surface of said face sheet, a fibrous paper backing layer and a release layer between one face surface paper backing layer and a release layer between one face surface of said paper backing layer and one surface of said adhesive layer and where said laminate is characterized by said paper layer having one machine glazed surface and a clay containing coating on its said glazed surface and having score lines formed in its second and outer face surface; said paper backing layer being relatively bulky, porous and uncompressed the paper in the paper layer at the score line being appreciably compacted to embrittlement, said paper backing layer of a given weight having more bulk per unit of basic weight than a super calendered paper of the same basic weight.
Claim 6
Dependent Claim
37 words
A laminate as in claim 3 where said paper backing layer is porous throughout except for its coated machine glazed surface, said paper backing layer having a noticeably rougher outer face surface than its machine glazed surface.
Claim 7
Dependent Claim
40 words
A laminate as in claim 3 or 4 where said paper backing layer has a BEKK smoothness on its machine glazed clay coated surface of about 360 and a BEKK smoothness of about 30 on its second and outer face.
Claim 8
Dependent Claim
23 words
A laminate as in claim 3 where the paper in said paper layer has at least 10% more bulk than super calendered paper.
