Abstract

The present subject matter provides a layered article for sealing an opening in a package for a high alcohol content product. The layered article has a facestock, a reclosure adhesive, a machine direction oriented film, and a sealing adhesive. The sealing adhesive provides a good long-term seal for the package that is resistant to degradation from alcohol. The machine direction oriented film provides an alcohol barrier between the product and the reclosure adhesive. Upon opening, the film tears clean and straight in the machine direction to allow a portion of the film to stay in contact with the package and another portion of the film to be pulled from the package to expose the opening. The reclosure adhesive provides resealing capabilities for the layered article after the initial opening of the package. The clean straight tear also provides a tamper evident feature for the package.

3. The layered article of claim 2 wherein the remaining portion of the layered article comprises a remaining portion of the film and a remaining portion of the sealing adhesive.

4. The layered article of claim 3 wherein subsequent to the initial peeling, the peeled portion of the layered article is capable of re-sealing the opening by releasably adhering the reclosure adhesive to the remaining portion of the film.

5. The layered article of claim 4 wherein the reclosure adhesive is capable of re-sealing the opening from 50 times to 150 times.

6. The layered article of claim 3 further comprising means to prevent a complete detachment of the peeled portion of the layered article from the remaining portion of the layered article upon peeling the layered article from the package.

7. The layered article of claim 3 wherein the tear in the film provides a visual indication of the initial peeling.

8. The layered article of claim 7 wherein the facestock is not completely opaque so that the visual indication of the initial peeling is observable through the facestock.

9. The layered article of claim 3 further comprising a tab at a periphery of the layered article, for grasping and peeling the layered article, the tab comprising a portion of the film that does not have the sealing adhesive disposed thereon.

10. The layered article of claim 9 wherein an edge of the tab begins at said at least one cut-out.

11. The layered article of claim 9 wherein the tab extends from the periphery of the layered article.

12. The layered article of claim 9 wherein the tab further comprises a portion of the facestock and a portion of the reclosure adhesive.

13. The layered article of claim 3 wherein the facestock has one or more layers selected from the group consisting of a polyolefin, polyethylene terephthalate, polyvinyl chloride or combinations thereof.

14. The layered article of claim 13 wherein said one or more layers of the facestock is biaxially oriented.

15. The layered article of claim 3 wherein the film comprises one or more polyolefins.

16. The layered article of claim 4 wherein the reclosure adhesive comprises a pressure-sensitive acrylic based solvent adhesive.

17. The layered article of claim 3 wherein the sealing adhesive comprises an acrylic based adhesive and has a greater adhesive strength than the reclosure adhesive.

18. The layered article of claim 3 further comprising printing, images, or other indicia on the film that is observable through the facestock.

19. The layered article of claim 3 further comprising printing, images, or other indicia on an exposed portion of the facestock.

20. The layered article of claim 3 further comprising a release liner disposed on the sealing adhesive.

21. A container for a high alcohol content product comprising:

a package, having an opening;

a layered article sealing the opening comprising

a facestock,

a reclosure adhesive disposed on the facestock,

a machine direction oriented film disposed on the reclosure adhesive, with at least one cut-out at a periphery of the film that is in line with a machine direction of the film,

a sealing adhesive disposed on the film, having an adhesive strength that is not significantly diminished by the product, for adhering the layered article to the package; and

wherein initially peeling the layered article from the package causes the film to tear from said at least one cut-out, in the machine direction of the film, forming

a peeled portion of the layered article that is peeled from the package and exposes the opening, the peeled portion of the layered article comprising the facestock, the reclosure adhesive, a peeled portion of the film, and a peeled portion of the sealing adhesive, and

a remaining portion of the layered article that is retained on the package, the remaining portion of the layered article comprising a remaining portion of the film and a remaining portion of the sealing adhesive and

wherein the machine direction oriented film has a reclosure surface, in the remaining portion of the layered article, to which the reclosure adhesive is adapted to bond to release the opening.

22. The container of claim 21 wherein the sealing adhesive and film completely cover the opening.

23. The container of claim 21 wherein the package comprises a flexible polymeric pouch comprising one or more film layers.

24. The container of claim 21 wherein subsequent to initially peeling the layered article from the package, the peeled portion of the layered article is capable of re-sealing the opening by releasably adhering the reclosure adhesive to the remaining portion of the film.

25. The container of claim 24 wherein the reclosure adhesive is capable of re-sealing the opening from 50 times to 150 times.

26. The container of claim 21 further comprising means to prevent a complete detachment of the peeled portion of the layered article from the remaining portion of the layered article upon peeling the layered article from the package.
