Abstract

A laminated packaging material for liquid food products may include a paper board having a non-white color or a film arranged on the paper board, and a pre-laminated hole arranged in an opening section of the paper board. A first contrast area may be arranged adjacent to the pre-laminated hole and printed in a first color that is selected such that a high contrast between the first color and the pre-laminated hole is achieved.

First claim

The invention claimed is:

1. A laminated packaging material for liquid food products comprising:
a paper board having a metal layer arranged on the paper board;
a pre-laminated hole arranged in an opening section of the paper board;
wherein a first contrast area is arranged adjacent to the pre-laminated hole and printed in a first color, the first color different from a color of the pre-laminated hole;
an opening identification mark printed in a second color, the opening identification mark configured to align an opening device in relation to the packaging material, the opening identification mark positioned within a second contrast area printed in a third color; and
wherein the second color and the third color are selected from a color pair of black-white, red-green, blue-orange, red-cyan, green-magenta, blue-yellow, yellow-purple, blue-orange, or vice versa.

2. A laminated packaging material for liquid food products according to claim 1 , wherein the first contrast area at least partly surrounds the pre-laminated hole.

3. A laminated packaging material for liquid food products according to claim 1 , wherein the first contrast area has an area that is at least 5%, larger than the pre-laminated hole.

4. A laminated packaging material for liquid food products according to claim 1 , further comprising a plurality of opening identification marks arranged at the pre-laminated hole and printed in the second color.

5. A laminated packaging material for liquid food products according to claim 1 , wherein the opening identification mark comprises
a two-dimensional code.

6. A laminated packaging material for liquid food products, comprising:
a pre-laminated hole arranged in an opening section of a paper board;
a first contrast area arranged adjacent to the pre-laminated hole and printed in a contrast color, the contrast color different from a color of the pre-laminated hole; and
an opening identification mark configured to align an opening device in relation to the packaging material and comprising a circular shape, the opening identification mark printed in a second contrast area, the second contrast area comprising a rectangular shape,
wherein the opening identification mark is printed in a second contrast color and the second contrast area comprises a third contrast color, the second contrast area spaced away from the first contrast area.
