Flexible laminate for packaging with integrated peelable portion
View Patent ↗A flexible laminate structure for making a package and methods for constructing such flexible laminate structures are described that provide a peelable portion integral to the laminate structure. An inner ink layer may be printed on the peelable portion that includes a promotional offer, such as in the form of a barcode, where the inner ink layer is not visible to a consumer without first peeling the peelable portion off the package due to the presence of one or more blocker ink layers.
1. A flexible laminate structure for a package comprising:
an outer layer;
an inner layer laminated to the outer layer;
at least one blocker ink layer disposed between the inner layer and the outer layer;
an inner ink layer disposed between the at least one blocker ink layer and the inner layer;
a cut line defined through part of a thickness of the laminate structure to form a removable portion that includes at least the inner ink layer, the at least one blocker ink layer, and the outer layer, wherein:
the at least one blocker ink layer obscures the inner ink layer from view through the outer layer;
the inner ink layer is visible on the removable portion after removal of the removable portion from the inner layer; and
the removable portion is configured to completely separate from the package; and
a pressure sensitive adhesive layer disposed adjacent the inner layer, within at least a portion of the location of the removable portion and extending across the cut line.
2. The flexible laminate structure of claim 1 further comprising an outer ink layer disposed between the outer layer and the blocker ink layer, wherein the removable portion includes the outer ink layer, and wherein the outer ink layer is visible through the outer layer.
3. The flexible laminate structure of claim 1 , wherein the pressure sensitive adhesive layer includes an area devoid of pressure sensitive adhesive so as to form a pull tab of the removable portion.
4. The flexible laminate structure of claim 1 , additionally comprising a tie layer disposed between the at least one blocker ink layer and the inner ink layer, wherein the tie layer is configured to maintain the pressure sensitive adhesive layer with the removable portion upon removal of the removable portion.
5. The flexible laminate structure of claim 1 , wherein the inner ink layer is adjacent the pressure sensitive adhesive layer.
6. The flexible laminate structure of claim 1 , wherein the pressure sensitive adhesive layer extends at least partially outside of the removable portion.
7. A flexible laminate structure for a package comprising:
an outer layer;
an inner layer laminated to the outer layer;
at least one blocker ink layer disposed between the inner layer and the outer layer;
an inner ink layer disposed between the at least one blocker ink layer and the inner layer;
a cut line defined through part of a thickness of the laminate structure to form a removable portion that includes at least the inner ink layer, the at least one blocker ink layer, and the outer layer, wherein:
the at least one blocker ink layer obscures the inner ink layer from view through the outer layer;
the inner ink layer is visible on the removable portion after removal of the removable portion from the inner layer; and
the removable portion comprises a perimeter region and a central region; and
a pressure sensitive adhesive layer disposed adjacent the inner layer, within at least the perimeter region, wherein the central region of the removable portion is free of pressure sensitive adhesive.
8. The flexible laminate structure of claim 7 , wherein the removable portion is configured to completely separate from the package.
9. The flexible laminate structure of claim 7 , wherein the pressure sensitive adhesive layer extends across the cut line.
10. The flexible laminate structure of claim 7 , wherein the inner ink layer is aligned with the central region of the removable portion.
11. The flexible laminate structure of claim 7 further comprising an outer ink layer disposed between the outer layer and the blocker ink layer, wherein the removable portion includes the outer ink layer, and wherein the outer ink layer is visible through the outer layer.
12. The flexible laminate structure of claim 7 , wherein the pressure sensitive adhesive layer includes an area devoid of pressure sensitive adhesive so as to form a pull tab of the removable portion.
13. The flexible laminate structure of claim 7 , additionally comprising a tie layer disposed between the at least one blocker ink layer and the inner ink layer, wherein the tie layer is configured to maintain the pressure sensitive adhesive layer with the removable portion upon removal of the removable portion.
14. The flexible laminate structure of claim 7 , wherein the inner ink layer is adjacent the pressure sensitive adhesive layer.
15. The flexible laminate structure of claim 7 , wherein the pressure sensitive adhesive layer extends at least partially outside of the removable portion.
