Abstract
Magnetic receptive media, the magnetic receptive media comprises at least one printable substrate layer and at least one layer formed from a hot melt polymer composition, the hot melt polymer composition comprising Greater than about 70% to about 95% magnetite and about 5% to less than about 30% thermoplastic polymer and methods of making and using the same.
Claims18
Magnetic receptive media, the magnetic receptive media comprises at least one printable substrate layer and at least one layer formed from a hot melt polymer composition, the hot melt polymer composition comprising:
- a) greater than about 70% to about 95% magnetite;
- and
- b) about 5% to less than about 30% thermoplastic polymer.
An in-line method of making a magnetic receptive media, the magnetic receptive media having dimensions of thickness, width and length, the method comprising:
- a) providing a hot melt composition comprising about 60% to about 95% magnetite and about 5% to about 40% thermoplastic polymer;
- and
- b) extruding said hot melt composition at an elevated temperature directly onto a printable substrate layer using a slot die head to form a roll or a sheet comprising the printable substrate layer and a layer of the hot melt composition at a speed of about 60 feet/minute to about 1000 feet/minute.
A continuous system for preparing a magnetic receptive media, the magnetic assembly comprising at least one printed substrate layer and at least one magnetic layer, the system comprising:
- an extruder for applying the magnetic layer;
- at least one slot die head in communication with the extruder;
- a moving substrate, the extruder supplies the slot die head with a polymeric magnetic composition comprising at least one polymer and at least one magnetic material, the magnetic material comprising magnetic particles, the slot die head applies the polymeric magnetic composition onto said substrate to form the magnetic layer onto the substrate;
- a printing press, the substrate is advanced through the printing press;
- and
- a controller;
- wherein the extruder and the printing press are in operative communication with the controller, so that the thickness of the magnetic layer and the speed of the moving substrate can be controlled by the controller.
