Abstract

A packaging material, including a laminate with a core material layer and having a plurality of delimited areas intended to form faces of a package is provided. At least one delimited area is provided with at least one pre-laminated hole and at least one compressed feature arranged adjacent to the pre-laminated hole. The at least one feature may include at least one line extending along at least a part of the perimeter of the pre-laminated hole.

First claim

The invention claimed is:

1. A packaging material, comprising:
a laminate with a core material layer, an outer layer, and an inner layer and having a plurality of delimited areas configured to form faces of a package, wherein at least one delimited area is provided with at least one pre-laminated hole and a plurality of compressed features arranged adjacent and spaced apart from the at least one pre-laminated hole, the pre-laminated hole comprising the outer layer and the inner layer, and wherein each compressed feature comprises a length, the length equal to or greater than a diameter of the at least one pre-laminated hole.

2. The packaging material according to claim 1 , wherein the at least one delimited area is configured to form an upper end of the package.

3. The packaging material according to claim 1 , wherein the at least one pre-laminated hold is configured to form a straw hole of the package.

4. The packaging material according to claim 1 , wherein at least one of the plurality of compressed features is arranged within 10 mm from the pre-laminated hole.

5. The packaging material according to claim 1 , wherein the plurality of compressed features is formed by embossing, debossing, or compression.

6. The packaging material according to claim 5 , wherein at least one of the plurality of compressed features is curved.

7. The packaging material according to claim 6 , wherein two of the plurality of compressed features are curved and positioned on opposite sides of the at least one pre-laminated hole.

8. The packaging material according to claim 7 , wherein each curved compressed feature extends between 30° and 150° of a periphery of the at least one pre-laminated hole.

9. A package, comprising a packaging material according to claim 1 , wherein the packaging material is closed by seals to form a closed package.

10. A method for providing a packaging material, comprising:
providing a core material layer with at least one hole;
laminating the core material layer to form a laminated packaging material with a pre-laminated hole, the pre-laminated hole comprising an outer layer and an inner layer; and
providing a plurality of compressed features adjacent and spaced apart from the pre-laminated hole prior to or after providing the core material layer with at least one hole, wherein each compressed feature comprises a length, the length equal to or greater than a diameter of the pre-laminated hole.

11. The packaging material according to claim 1 , wherein the at least one delimited area comprises an edge defining a boundary of the delimited area, and wherein at least one of the plurality of compressed feature is spaced apart from the edge of the delimited area.

12. The packaging material according to claim 1 , wherein at least one of the plurality of compressed feature has a thickness between 0.5 mm to 2 mm.

13. The method for providing a packaging material according to claim 10 , wherein the pre-laminated hole is formed on a delimited area of the laminated packaging material, the delimited area comprising an edge defining a boundary of the delimited area, and wherein at least one of the plurality of compressed features is spaced apart from the edge of the delimited area.

14. The method for providing a packaging material according to claim 10 , wherein at least one of the plurality of compressed features has a thickness between 0.5 mm to 2 mm.

15. The packaging material of claim 1 , wherein the packaging material comprises two compressed features, the two compressed features positioned on opposite sides of the at least one pre-laminated hole.

16. The packaging material of claim 1 , wherein at least one of the plurality of compressed features is thinner than the pre-laminated hole.

17. The packaging material of claim 1 , wherein at least one of the plurality of compressed features comprises an upward deflection on a bottom side of the compressed feature and a flat surface on the top side of the compressed feature.
