Abstract

A packaging material comprising a plurality of magnetisable portions thereon comprising at least one detectable magnetisable portion per package to be formed from the packaging material is disclosed. At least one of the magnetisable portions provides a first magnetic mark carrying a magnetic field pattern.

Claims

1. Packaging material comprising at least one magnetisable portion per package to be formed from the packaging material such that each package possesses a visual exterior, said packaging material comprising a laminate with a layer of paper or paperboard, wherein

said at least one magnetisable portion is provided directly on one surface of said paper or paperboard layer,

said at least one magnetisable portion is arranged so as not to interfere with the visual exterior of the package, and

said at least one magnetisable portion is positioned at a place on the packaging material that is within a joint of overlapping edges of the packaging material when the packaging material is folded and sealed to produce the package,

wherein said paper or paperboard layer is covered by plastic coatings on each side thereof.

2. Packaging material according to claim 1, wherein said at least one magnetisable portion is provided through a printing operation.

3. Package formed by folding and sealing of the packaging material according to claim 1, wherein said at least one magnetisable portion is provided on that surface of the paper or paperboard layer which is facing inwardly of the package.

4. Package formed by folding and sealing of the packaging material according to claim 1, wherein said at least magnetisable portion is applied through a printing operation.
