Abstract
A pattern of coating is applied to a label, such that the coating covers the periphery, including a portion of the top surface of the label, and overlaps onto the liner ply area adjacent to the label. The coating is selected to form a stable and resistant film that spans continuously along the label edge and liner surfaces. The coating reduces adhesive ooze when the label is exposed to elevated ambient temperatures and pressures.
Claims48
A label comprising:
- a label ply having a label face and a label back;
- a liner ply having a first region and a second region;
- an adhesive applied between said label back and said liner ply such that said label ply is aligned substantially in register with, and releasably held to said first region of said liner ply;
- and
- a barrier coating arranged to overlap at least a portion of said label face and said second region of said liner ply so as to limit said adhesive from exuding beyond said barrier coating by passing thereunder.
A label comprising:
- a label ply superposed on a liner ply having an adhesive therebetween, said label ply having a label face and a label periphery, and said liner ply defining an outer liner ply portion extending beyond at least a portion of said label periphery;
- and
- a barrier coating overlapping said label periphery of said label face and said outer liner ply portion of said liner ply so as to limit exusion of said adhesive beyond said barrier coating.
A label sheet comprising:
- a liner ply having a ply face;
- a plurality of label plies, each of said plurality of label plies having a label face;
- an adhesive applied between each of said plurality of label plies and said liner ply;
- and,
- a barrier coating arranged to overlap at least a portion of each label face of said plurality of label plies and said ply face of said liner ply so as to limit said adhesive from exuding beyond said barrier coating by passing thereunder.
A label sheet according to label 15, wherein said plurality of label plies are spaced apart on said liner ply so as to be non-abutting.
A label sheet according to label 15, wherein select ones of said plurality of label plies are spaced on said liner ply so as to be abutting.
A label comprising:
- a form having a window of material removed therefrom;
- a liner ply secured to said form such that said liner ply covers said window;
- a label ply having a label face and a label periphery, said label ply positioned within said window and releasably held to said liner ply;
- and
- a barrier coating applied around at least a portion of said label periphery of said label face overlapping onto said liner ply within said window.
A combination label and form comprising;
- a form having a form face;
- a liner ply adhesively held to said form;
- a label having a label face and a label back, said label back releasably held to said liner ply;
- and
- a barrier coating applied to said label such that said barrier coating overlies at least a portion of said label face and extends onto said form adjacent to said liner ply, so as to limit said adhesive from exuding beyond said barrier coating by passing thereunder.
A label sheet comprising:
- a liner ply having a ply face;
- a plurality of label plies, each of said plurality of label plies having a label face and a label periphery;
- an adhesive applied between each of said plurality of label plies and said liner ply;
- and
- a barrier coating that overlaps and bridges at least a portion of said label peripheries of adjacent ones of said plurality of label plies on respective label faces, so as to limit said adhesive from exuding beyond said barrier coating by passing thereunder so as to become exposed on a face of said label sheet.
