Packaging article and method with particular tearing slit arrangement
View Patent ↗A packaging article including a flap for opening and reclosing the packaging article. The packaging article comprises a flexible packaging material and a label. The flexible packaging material includes the flap and a plurality of slits defining at least a portion of a boundary of the flap. The plurality of slits are substantially parallel to and spaced from one another and have a length dimension. When applying to the flap a tearing force directed substantially perpendicularly to the length dimensions of the plurality of slits, the flap can be opened by the tearing force tearing the flexible packaging material between the plurality of slits. A first portion of the label is affixed to a portion of the flap. A second portion of the label is adapted to be repeatedly removably adhered to a portion of the flexible packaging material adjacent the flap such that the flap can be opened and reclosed. The packaging article may be a ream wrapper.

2. The packaging article of claim 1 , wherein the packaging article is a ream wrapper.
3. The packaging article of claim 1 , wherein a midpoint of the length dimension of each of the plurality of slits is offset from one another.
4. The packaging article of claim 3 , wherein the plurality of slits are arranged such that the midpoints of the length dimensions of each of the plurality of slits form a shape comprising an angle or an arc.
5. The packaging article of claim 1 , wherein the label covers at least one of the plurality of slits.
6. The packaging article of claim 1 , wherein the label covers a majority of the plurality of slits.
7. The packaging article of claim 1 , wherein the flexible packaging material comprises a polymer film, a cellulose material, or combinations thereof.
8. The packaging article of claim 1 , wherein the flexible packaging material comprises a polymer film having a thickness ranging from 100 gauge to 400 gauge.
9. A method for packaging a product comprising:
providing a packaging article comprising a flexible packaging material, the flexible packaging material comprising a flap and a plurality of slits defining at least a portion of a boundary of the flap, wherein the plurality of slits are substantially parallel to and spaced from one another and have a length dimension such that when applying to the flap a tearing force directed substantially perpendicularly to the length dimensions of the plurality of slits the flap can be opened by the tearing force tearing the flexible packaging material between the plurality of slits, wherein the plurality of slits are arranged such that the length dimensions are oriented in a substantially perpendicular direction in relation to the tearing force when opening the packaging article by the flap;
providing a label, wherein a first portion of the label is affixed to a portion of the flap, and wherein a second portion of the label is adapted to be repeatedly removably adhered to a portion of the flexible packaging material adjacent the flap such that the flap can be opened and reclosed; and
enclosing the product in the packaging article.
10. The method of claim 9 , wherein a midpoint of the length dimension of each of the plurality of slits is offset from one another.
11. The method of claim 9 , wherein the step of providing the label comprises adhering the label to the flexible packaging material so that the label covers at least one of the plurality of slits.
12. The method of claim 9 , wherein the product comprises a ream of paper.
13. A wrapped article including a flap for opening and reclosing the wrapped article, the wrapped article comprising:
a ream of paper;
a ream wrapper comprising a flexible packaging material, the flexible packaging material comprising the flap and a plurality of slits defining at least a portion of a boundary of the flap, wherein the plurality of slits are substantially parallel to and spaced from one another and have a length dimension such that when applying to the flap a tearing force directed substantially perpendicularly to the length dimensions of the plurality of slits the flap can be opened by the tearing force tearing the flexible packaging material between the plurality of slits, wherein the plurality of slits are arranged such that the length dimensions are oriented in a substantially perpendicular direction in relation to the tearing force when opening the packaging article by the flap; and
a label, wherein a first portion of the label is affixed to a portion of the flap, and wherein a second portion of the label is adapted to be repeatedly removably adhered to a portion of the flexible packaging material adjacent the flap such that the flap can be opened and reclosed.
14. The wrapped article of claim 13 , wherein a midpoint of the length dimension of each of the plurality of slits is offset from one another.
15. The wrapped article of claim 14 , wherein the plurality of slits are arranged such that the midpoints of the length dimensions of each of the plurality of slits forms a shape comprising an angle or an arc.
16. The wrapped article of claim 13 , wherein the tearing force is substantially directed towards a midpoint of the length dimension of each of the plurality of slits.
17. The wrapped article of claim 13 , wherein the label covers at least one of the plurality of slits.
18. The wrapped article of claim 17 , wherein the label covers a majority of the plurality of slits.
19. The wrapped article of claim 13 , wherein the label provides at least a partial moisture seal when the label is adhered to the portion of the flexible packaging material adjacent the flap before the flap is opened and when the flap is reclosed.
20. The wrapped article of claim 13 , wherein the second portion of the label is adapted to be pulled away from the portion of the flexible packaging material adjacent the flap to provide the tearing force.
21. The wrapped article of claim 13 , wherein the ream wrapper comprises a polymer film, a cellulose material, or combinations thereof
22. The wrapped ream article of claim 21 , wherein the ream wrapper comprises a polymer film having a thickness ranging from 100 gauge to 400 gauge.
23. A method of forming a packaging article comprising:
providing a flexible packaging material having a surface;
forming a plurality of slits defining at least a portion of a boundary of a flap, wherein the plurality of slits are substantially parallel to and spaced from one another and have a length dimension such that when applying to the flap a tearing force directed substantially perpendicularly to the length dimensions of the plurality of slits the flap can be opened by the tearing force tearing the flexible packaging material between the plurality of slits, wherein the plurality of slits are arranged such that the length dimensions are oriented in a substantially perpendicular direction in relation to the tearing force when opening the packaging article by the flap.
