Claims
- 1. A package comprising:
- a package wall having an interior surface and an exterior surface;
- an axially-oriented material disposed proximate to the interior surface of the package wall, the package wall being comprised of a laminate material comprising the following package layers from exterior to the interior surface,
- an exterior LDPE layer,
- a paperboard layer adjacent to the exterior LDPE layer,
- an internal LDPE layer interior to the paperboard layer,
- a barrier layer adjacent to the internal LDPE layer, and
- an interior contact layer adjacent to the barrier layer, the interior contact layer including the axially-oriented material; and
- at least one tear strip formed in the package wall, the tear strip being defined by a pair of generally parallel frangible tear lines;
- wherein each tear line includes a linear cut formed in the exterior of the package wall, with the linear cut being disposed generally parallel to the axial orientation of the axially-oriented material.
- 2. A package according to claim 1, wherein the parallel creases of the tear line extend into the barrier layer.
- 3. A package according to claim 2, wherein the depth of the linear cut extends from the exterior surface of the package wall to a point just short of the barrier layer.
- 4. A package according to claim 3, wherein the barrier layer comprises an aluminum foil layer.
- 5. A package according to claim 3, wherein the barrier layer comprises an EVOH layer.
- 6. A package according to claim 3, wherein the interior contact layer comprises a mono-oriented LDPE layer.
- 7. A package according to claim 1, further comprising at least one adhesive tie layer disposed between adjacent package layers.
- 8. A package according to claim 1, wherein each tear strip terminates in a respective tab member.
- 9. A package according to claim 8, wherein the package includes a lateral edge, and each tab member is disposed between a tab crease line and the lateral edge of the package.
- 10. A package according to claim 9, wherein each tab member is in sealing contact with a wall of the package, and an adhesive material is disposed between each tab member and the wall of the package.
- 11. A carton blank for forming a reducible volume container comprising the following:
- a laminated blank body having a top and a bottom;
- a plurality of bottom creases formed in the bottom of the blank body to define bottom flaps that are adapted to be folded and sealed to form a bottom surface of a finished carton, including a horizontal bottom crease extending substantially between the sides of the carton blank, defining first, second, third, and fourth bottom flaps between the horizontal bottom crease and the bottom of the carton blank, with the bottom flaps being separated from one another by lower portions of the vertical creases;
- a plurality of top creases formed in the top of the blank body, the top creases defining top flaps that are adapted to be folded and sealed to form a top surface of a finished carton, including a horizontal top crease extending substantially between the sides of the carton blank, defining first, second, third, and fourth top flaps between the horizontal top crease and the top of the carton blank, with the top flaps being separated from one another by upper portions of the vertical creases;
- a plurality of substantially equidistantly spaced vertical creases extending from the top of the carton blank to the bottom of the carton blank, separating the carton blank into first, second, third, fourth, and fifth vertical panels;
- a monoaxially oriented material disposed on an inner surface of the carton blank; and
- a plurality of tear strips disposed between the horizontal top crease and the horizontal bottom crease, with each of the tear strips being defined by a pair of generally parallel frangible tear lines;
- wherein each tear line includes a linear cut formed in an exterior surface of the carton blank, with the linear cut disposed parallel to the orientation of the monoaxially oriented material.
- 12. A carton blank according to claim 11, further comprising:
- a top side strip disposed between a top tear strip and the horizontal top crease; and
- a bottom side strip disposed between a bottom tear strip and the horizontal bottom crease.
- 13. A carton blank according to claim 11, wherein each tear strip terminates in a respective tab member.
- 14. A carton blank according to claim 13, wherein the carton blank includes a lateral edge, and each tab member is disposed between a tab crease line and the lateral edge of the carton blank.
- 15. A carton blank according to claim 13, wherein each tab member is adapted for sealing contact with a surface of the fifth panel of the carton blank, and at least a portion of the surface of the fifth panel is coated with an adhesive material.
- 16. A carton blank according to claim 11, wherein the laminated material comprises the following layers:
- an exterior LDPE layer;
- a paperboard layer adjacent to the exterior LDPE layer; and
- an oriented metallized polymer layer adjacent to the paperboard layer.
- 17. A carton blank according to claim 16, wherein the depth of the linear cut extends from the exterior surface of the package wall to a point just short of the oriented metallized polymer layer.
