Problems solved by technology

One problem with this type of registration mark is that it consumes a non-negligible area of ​​what becomes the package surface
Another problem is that such registration marks must rely on printing performed on the web in good alignment with other operations

Embodiment Construction

[0011] Such as figure 1 As shown, the web of packaging material, such as a laminate, includes more than two magnetizable portions on the web. The web comprises at least one spot per package to be formed from the packaging laminate. Additionally, the web provides at least one preparation feature for facilitating finishing of the package. The at least one fabricated feature is aligned with a magnetic field marking in the at least one magnetizable portion. For example, if figure 1 As shown, fold lines are generated in the web for enabling fast and reliable finishing of the package. When the fold line is generated, a mark is formed in the form of a magnetic field in the magnetizable portion at the same time as the fold line is generated. A mechanism with magnetized elements, ie a roller with patterned grooves / protrusions, is provided for generating the fold lines. Then, you can ensure that the magnetization marks are aligned with the fold line generation operation. The magne...

Abstract

A packaging material comprising a plurality of magnetisable portions thereon is disclosed. The packaging material is formed into a tube, sealed at one end, filled with content, sealed again to enclose the content, cut, and formed to a package. The magnetisable portions are provided as at least one spot per package to be formed from the packaging material. At least one of the magnetisable portions provides a first magnetic mark carrying a magnetic field pattern providing position information through which any twist of the formed tube can be detected.

Description

technical field [0001] The present invention relates to a magnetisable packaging material comprising magnetisable portions, wherein the material is intended to be formed, for example, into 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 finishing package operations such as forming, sealing, folding, etc., guide indicia, for example for optical reading, are provided to guide the operation. Such guide marks are sometimes referred to as register marks. Register marks for optical reading are provided during printing of packaging laminates, where for example decoration or product information is printed 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...
