Abstract

The practical application of incorporating magnetic receptive particles embodied in the formulation of an extruded film will produce a magnetic receptive film with properties that will adhere to magnets. Furthermore, incorporating the technique of co-extrusion, one can produce a print media with a magnetic receptive core while maintaining an un-altered first and third layers.

Claims

1. A film structure comprising a magnetic receptive core layer with one or more outer layers suitable to accept printing.

2. An extruded film structure comprising a magnetic receptive core layer with one or more outer layers suitable to accept printing.

3. A co-extruded film structure comprising a magnetic receptive core layer with one or more outer layers suitable to accept printing.

4. A cast film structure comprising a magnetic receptive core layer with one or more outer layers suitable to accept printing.

5. A film embodying ferromagnetic material with one or more outer layers biaxially-oriented to improve outer layer opacity.

6. A film embodying ferromagnetic media suitable for adhering to magnets.
