Abstract

In a method of providing a packaging laminate with an identification code the packaging laminate is subjected to a magnetic field, thus magnetising a matrix of magnetic domains in the packaging laminate. Each magnetic domain is made up of a number of the magnetisable particles. A method of identifying a package is also disclosed. The package has walls of a packaging laminate comprising magnetisable particles. The method comprises the steps of subjecting the packaging laminate to a magnetising magnetic field, thus magnetising a matrix of magnetic domains in the packaging laminate, and detecting an emitted magnetic field emitted by the magnetic domains in the matrix. A package having an identification code is also described.
