ferrite or magnetic regions hereinafter referred to as ferrite regions may be accomplished by several exemplary methods in a first exemplary embodiment the ferrite regions are formed from magnetic gaskets to form a re closure system as discussed above the magnetic gaskets are made from commercially available flexible magnetic sheeting such as magnetic sheets made by plastiform division of arnold engineering magnetic sheets of this type are conventionally used for magnetic tags signs u201c refrigerator magnets u201d and the like the magnetic sheets are pre cut prior to placement on the blank 100 to the desired shape and size the magnetic gaskets are then bonded to the flap or container blank using a conventional labeling machine adapted for this purpose various types of labeling equipment are used in the packaging industry to apply labels to almost any type container with a high degree of placement accuracy and at production rates of many thousands of containers hour the magnetic gaskets may have pre applied pressure sensitive adhesive u201c psa u201d or a gluer can be used to apply adhesive in the desired pattern to each container blank application of the magnetic gaskets may be applied u201c inline u201d on the same continuous production line that prints cuts and scores the base substrate web in form to produce individual carton blanks according to this embodiment the magnetization pattern spatial extent of the zonal bands of magnetization and their polarity are exactly the same for the flap magnetic strip and the container opening magnetic strip for example if spatial arrangement of the opposing magnetic gaskets is exactly the same but with opposite magnetic polarity the magnetic force produced between the flap and the container will be.
