A method for treating a package. In the method a first plastic film sack (14) is provided, that has a flexible wall (18) comprising a plastic film (3), the wall (18) having an outer surface (5). A second plastic film sack is provided. A product of powder form is provided that has an upper size limit which is the particle size smaller than 1 mass-percent of the particles of the product of powder form, which upper size limit is at most 5000 microns and a lower size limit which is the particle size bigger than 1 mass-percent of the particles of the product of powder form. The product of powder form is packed in the first plastic film sack (14), and the first plastic film sack is, at least partly, placed upon the second plastic film sack. According to the invention, such a first plastic film sack is provided in which at least a part of the outer surface (5) of the flexible wall (18), the roughened surface-part (6), comprises antislip protrusions (7) which antislip protrusions (7) are constituted by roughening particles, of polymer material, fixed to the outer surface (5) and the height (8), above the outer surface (5) of the plastic film wall, of at least a part of the antislip protrusions (7) is bigger than the lower size limit of the product of powder form.

An iron core for the magnetic induction of a visual information displaying element with a magnetic flip plate, wherein the display element comprises one or more permanent-magnetic flip plates magnetized perpendicular to their face and suitable for the direct or indirect display of the information. It is provided with one or more exciting coils with an iron core with a repolarizable remanent induction adapted to produce a magnetic field and with a coercive force less than the coercive force of the permanent magnet in the flip plate. On the end of the core facing the display element a profiled body is closely fitted, which is made of a magnetic material having a higher initial permeability than the initial permeability of the iron core and which is provided with a profiled cut-out corresponding to the cross-section of the end of the iron core.
