Definitions

  • the present invention relates to a method of providing a packaging laminate with an identification code.
  • the invention also relates to a method of identifying a package, said package having walls of a packaging laminate comprising magnetisable particles.
  • the present invention relates to a package having walls of a packaging laminate, said laminate comprising magnetisable particles.
  • identification codes e.g. for identifying a particular location on the package or for identifying an individual package.
  • One type of identification code is the optical code, usually a bar code. Bar codes can be printed on the package material along with the decor.
  • a disadvantage in connection with bar codes is that optical vision is needed for reading the code. Therefore, the bar code has to be visible on the package and must not be covered by, e.g., a protective film.
  • Another disadvantage is that the bar code is static and cannot be changed once it has been printed. Further, the bar code may be considered a disturbing element in the design of the package.
  • This packaging laminate contains magnetisable particles in at least one of its layers.
  • the magnetisable particles have been used for marking a single point on the packaging laminate in order to facilitate printing in register with crease lines on the packaging laminate.
  • Another object is to provide a package with an identification code that can be changed during the production or life of a package.
  • Yet another object is to provide a package that is easily traceable at a relatively low cost.
  • the packaging laminate comprises magnetisable particles and is subjected to a magnetic field, thus magnetising a matrix of magnetic domains in the packaging laminate, each magnetic domain being made up of a number of the magnetisable particles.
  • the magnetisation of the matrix of magnetic domains is divided into at least two steps, wherein in a first step a first group of magnetic domains are magnetised, and in a second step a second group of magnetic domains are magnetised.
  • the identification code can be built up during different stages of treatment of the packaging laminate.
  • At least some of the magnetic domains in the first group may also belong to the second group.
  • the magnetisation of some magnetic domains may thus be changed during different stages of treatment of the packaging laminate.
  • the inventive method of identifying a package comprises the steps of subjecting the packaging laminate to a magnetising magnetic field, thus magnetising a matrix of magnetic domains in the packaging laminate, each magnetic domain being made up of a number of the magnetisable particles, detecting an emitted magnetic field emitted by the magnetic domains in the matrix.
  • a variant of the method according to the invention further comprises the steps of determining the identity of the package based on the detected magnetic field, and reading data related to the identified package in a database. This method makes it possible to trace an individual package back to its production.
  • the magnetisation of the matrix of magnetic domains may be divided into at least two steps, wherein in a first step a first group of magnetic domains are magnetised, and in a second step a second group of magnetic domains are magnetised. Different parts of the identification code can thereby be created during different stages of the production of the package.
  • the first group of magnetic domains are magnetised before the packaging laminate is formed into the package and the second group of magnetic domains are magnetised after the packaging laminate has been formed into the package.
  • the identification code may in this way be used for storing first data on, e.g., a sterilization of the empty package, and then, e.g., data on a heat treatment of the package once it is filled and sealed.
  • At least some of the magnetic domains in the first group may belong also to the second group. In this manner part of the identification code may be magnetised at one stage of the production of the package and altered at another stage of production.
  • the package of the invention has an identification code comprising a matrix of magnetic domains, each magnetic domain being made up of a number of the magnetisable particles.
  • the identification code of the package may be used for tracing an individual package back to its production.
  • the matrix is advantageously a six by six matrix. This enables a large number of individual codes but can still be fitted on most package sizes.
  • FIG. 1 is a schematic representation of a package with an identification code according to the invention.
  • FIG. 2 is a schematic representation of a package with an identification code according to another embodiment of the invention.
  • the package 1 shown in FIG. 1 is a Tetra Brik® beverage package.
  • the package 1 is made of a packaging laminate as described in Applicant's WO 03/095198.
  • This packaging laminate has magnetisable particles embedded in at least one of its layers.
  • An identification code 2 is provided on a wall 3 of the package 1 in the form of a six by six matrix of magnetic domains 4 .
  • Each magnetic domain 4 is made up of a number of magnetisable particles.
  • each magnetic domain 3 can be given one of three values: plus, minus or no magnetic charge.
  • a six by six matrix as many as 1.5 ⁇ 10 17 different codes can be created.
  • the identification code 2 may be used more independently, without the use of a database identifying individual packages 1 .
  • different groups of magnetic domains 4 in the matrix 2 may be used for storing data on different stages of the production of the package. For instance, a first group 5 of magnetic domains 4 may be used for registering data on the type of packaging material used (thickness, type of plastic film, presence of aluminum layer etc.). A second group 6 of magnetic domains 4 may be used for registering data on the sterilization of the material web. A third group 7 of magnetic domains 4 could be used for storing data on the contents of the package 1 . Some magnetic domains 4 may belong to more than one group of magnetic domains 4 .
  • a fourth group 8 of magnetic domains could be used for registering data on a possible treatment of the package 1 after filling, and this fourth group 8 could include some or all of the magnetic domains 4 in one or more of the other groups, e.g. the third group 7 .
  • the magnetisation of some or all of the magnetic domains 4 may be changed a number of times during the production of the package 1 , from the raw material web to the finished package 1 .
  • a less complex identification code may use a smaller matrix, e.g. a three by three matrix, when it is not necessary to identify individual packages, but only batches of production.
  • the number of magnetic domains 4 in the matrix 2 is theoretically limited only by the size of the area available on the package 1 , the possible resolution of the magnetisation means and the detector used, and the distance necessary between the domains 4 for avoiding crosstalk. In practice, the size of the matrix will be limited by the size of the smallest package for which it is intended to be used.
  • the identification code 2 can be read regardless of whether the package 1 is standing up or lying on the side, as long as the orientation of the package 1 is known.
  • the magnetisation of the matrix 2 can be done using electrically changeable magnetisation devices formed in a corresponding matrix.
  • the magnetisation device can be arranged in the converting machine, in the package machine or along the conveyors after the filling machine.
  • the device used for reading the identification code may have magneto resistive sensors, GMR sensors or similar, formed into a matrix corresponding to the matrix 2 to be read.
  • the sensors should be able to sense both static and dynamic fields, such that it is possible to read the identification code 2 when the package 1 is standing still or moving.
  • the reading distance can be up to a couple of millimetres.
  • the sensors could also be arranged in a row or column, corresponding to a row or column in the matrix 2 to be read.
  • the identification code 2 is in such case read by moving the package 1 past the sensors, or vice versa.
  • said magnetic domains can be given a level of plus and minus charge that afterwards can be detected.
  • the number of available coding combinations in a matrix increases dramatically, given the same number of magnetic domains. For example, if given three levels of charge, the possible charge in one domain is +3, +2, +1, 0, 1, 2, 3 equals seven possibilities for each magnetic domain.
  • the number of charging levels can be more or less than the exemplified three, within the scoop of the invention. The number of charging levels can in practical use be limited by the resolution in the detector used and the distance between the detector and the matrix.
  • the invention is of course not limited to the specific shape of package shown in the drawings.
  • the skilled person will realize that the identification code of the invention may be applied to any kind of package manufactured from a packaging material containing magnetisable particles.
