ABSTRACT:
A method of encapsulating a toxic material with a resinous plastic wherein the toxic material is admixed and coated with the resinous plastic to result in an encapsulated product having a protective skin thereover. The method involves an extrusion step followed by a severing of the extruded product into discrete particles for either subsequent injection or compression molding or additional extruding with additional resinous plastic. Geometric forms result which can indicate the type of toxic material as well as be of a size so as not to be ingested by animals and have imprinted warning indicia. Liquid as well as solid toxic materials can be encapsulated.
