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.

Abstract: A system and a method for production of a packaging laminate that comprises a layer containing magnetizable particles. The method involves marking faults, such as single spot defects and splices, on the packaging laminate by the application of a magnetic field to make a magnetic mark on the packaging laminate. A packaging device is arranged to sense the presence of the magnetic mark related to a package made from the packaging laminate.

Abstract: The invention relates to a method and an apparatus for the supply of a gas or a gas mixture at a predetermined temperature to a processing station in a filling machine in which gas or gas mixture pressurised to above atmospheric is passed through an electrically heated heating unit (2, 3; 6, 7). This includes a sensor sensing the temperature of the gas whose output signal is fed back to a gas temperature regulator unit (not shown) which in its turn is coupled to the heating unit with a view to regulating the temperature of the gas flowing out from the heating unit (2, 3; 6, 7). The heating unit (7) is formed to an electrically conductive shell or a cavity (6) through which the gas or gas mixture is passed positively and regulated.
