Embodiment Construction

[0074] Rolls of packaging material, such as laminated materials, comprising multiple magnetizable parts such as figure 1 shown in . The web includes at least one detectable magnetisable portion of each package to be formed from the packaging material. Further, the web provides at least one manufacturing feature for enhancing the finish of the package. The at least one fabricated feature is aligned with the magnetic field marking in the at least one magnetizable portion. For example, if figure 1 As shown in , making crease lines in the web is used to achieve a quick and reliable finish of the package. During the making of the crease lines, marks are formed in the magnetisable part simultaneously with the making of the crease lines as predefined magnetic fields. The mechanism used to make the crease lines (ie rollers with patterned grooves / protrusions) may have magnetized elements. The magnetized marks are then ensured to be aligned with the crease line making operation. ...

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.

Description

technical field [0001] The present invention relates to a sheet or web of packaging material comprising at least one detectable information-bearing indicia for each packaging container to be formed from said web or sheet. In particular, the present invention relates to rolls or sheets of packaging material comprising a base layer of paper or paperboard and an outer liquid-impermeable layer of polyolefin for reforming into liquid and / or solid Packaging containers for food transport and handling. The invention also relates to packaging containers produced from sheets or webs of said packaging material by forming, filling and sealing processes. The invention also relates to a method for manufacturing a web of packaging material comprising at least one detectable information-carrying marking for each packaging container (package) to be formed from said web. Furthermore, the invention relates to a method for forming a filled seal from a sheet or web of packaging material comprisi...
