Abstract: Provided herein are compositions comprising substrates that contain polymeric materials or non-magnetic, paramagnetic, or diamagnetic metal objects, and films or inks that contain ferromagnetic materials in which the films or the ferromagnetic materials are transparent. Also provided herein are methods of fabricating the substrates. Further provided herein are ferromagnetic material films containing transparent or translucent films that comprises ferromagnetic materials. The coating imparts functionality to the film such that the film is capable of being mechanically separated from the polymeric materials or non-magnetic, paramagnetic, or diamagnetic metal objects using a commercial magnetic separator. The transparent, food-safe ink composition, which can be printed using high-speed flexographic, gravure, intaglio, offset printing or pad printing consists of an ingestible magnetically susceptible pigment capable of rendering the printed template with magnetically active properties.

Abstract: Provided herein are methods and compositions comprising a non-toxic ferromagnetic ink composition. Also provided herein are plastic objects containing a surface coating of a food-safe ferromagnetic ink composition. The coating imparts functionality to a plastic object such that the object is capable of being mechanically separated from waste stream using a commercial magnetic separator. The food-safe ink composition, which can be printed using high-speed flexographic, intaglio, offset printing or pad printing, combined with heat transfer printing or hot foil stamping consists of an ingestible magnetically susceptible pigment capable of rendering the printed template with magnetically active properties. The surface of the plastic object described can consist of geometric designs which increase printable surface area without significant changes in dimensions of the said object.
