The present invention relates to a method for visualization of non-visible information on a packaging material to provide traceability. The method comprises the steps of: reading the non-visible information from the packaging material by means of a magnetic head reader, processing the non-visible information in a central processing unit together with additional new non-visible information, and printing an optional portion of the amount of combined non-visible information onto the packaging material as a traceability marking. The invention also relates to a device for carrying out the method and a packaging line with a filling machine making use of the device.

Method of sterilising a packaging material () by means of a sterilising agent in liquid form, comprising the steps of: providing a packaging material () to be sterilised, providing a source () of sterilising agent in liquid form, forcing the liquid sterilising agent through a nozzle () to form a jet () directed towards the packaging material, subjecting the jet () of liquid sterilising agent to a controlled, periodic disturbance causing the jet () of liquid sterilising agent to form a train () of droplets of controlled, essentially uniform size and controlled rate, moving the packaging material () in relation to said nozzle () or vice versa, whereby said train () of droplets forms a coating () of sterilising agent of controlled thickness and controlled coverage on the packaging material (), and vaporising the film of sterilising agent on the packaging material (). The invention also concerns a similar method and devices for implementing said methods.
