Abstract: A magnetically resealable bag including a polymer substrate. The polymer substrate including a front panel, a back panel, a closed bottom and an opening. The inside of the opening including a first side strip and a second side strip. The first side strip and second side strip include a layer of a magnetizable composition, and at least one layer of a polymer material arranged to provide a covering over the layer of the magnetizable composition. A top portion of the first side strip is coupled to the inside at the front panel of the bag and a top portion of the second side strip is coupled to the inside of the back panel of the bag, and a bottom portion of the first and second side strip is free of the inside of the opening. The first side strip and second side strip are aligned and permanently magnetized.

Abstract: A unitary method of making a printed magnetic assembly is disclosed, the printed magnetic assembly comprising at least one magnetic layer and at least one printable substrate layer in the form of a sheet or roll, the method comprising the steps of: a) providing a molten magnetic hot melt composition comprising about 70 wt-% to about 95 wt-% of at least one magnetic material and about 5 wt-% to about 30 wt-% of at least one thermoplastic binder; b) directly extruding the magnetic composition at an elevated temperature when it is pliable onto the printable substrate layer with a single screw or double screw extruder to form at least one discrete thin magnetic layer on the printable substrate to form a layered sheet or roll; d) feeding the roll or sheet through a printing press at a speed of about 60 feet/minute to about 1000 feet/minute; e) printing on the printable substrate layer using at least one method selected from the group consisting flexo, gravure, digital and screen printing; and f) permanently magnet
