Embodiment Construction

[0020] In order to understand the provision of magnetic labels, magnetic ink will be briefly discussed. Accordingly, magnetic inks are provided so that magnetisable portions can be provided on packaging materials which are used to form such as food packaging, for example beverage or food containers or as basic or supplementary products for the preparation of food or beverages. container. The ink includes magnetisable particles for providing the magnetic characteristics of the magnetisable portion.

[0021] The ink further includes a solvent. The role of the solvent is to keep the system dispensing both flowing and open ink while printing. The solvent is either water-based or monomer-based. Examples of solvents are ethanol, ethyl acetic acid, water, isopropanol, ethylene glycol, or retarder solvents.

[0022] Inks further include binders such as acrylates, styrene propylene polymers, polyurethanes, nitrocellulose, polyamides or latex. The binder may comprise a mixture of s...

Abstract

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

Description

technical field [0001] The present invention relates to a packaging material comprising a magnetisable portion, wherein said material is used to form, for example, food packaging. Background technique [0002] In the packaging art of forming packaging containers from packaging laminate, it is known to provide the packaging laminate as a web before or during the formation of the packaging container. When performing operations for finishing the package such as forming, sealing, folding, etc., guide markings, for example for optical reading, are provided to guide the operation. Such guide marks are sometimes referred to as register marks. Registration marks for optical reading are provided during printing of packaging laminates, for example when printing decoration or product information on the packaging material. One problem with this type of registration mark is that it consumes a non-negligible area of ​​what becomes the surface of the package. Another problem is that suc...
