1. A sheet for delivery of an agent to a shredding mechanism of a paper shredder comprising:

  • a substrate that is configured to be passed through the shredding mechanism of the paper shredder;

    a lubricating agent carried by the substrate; and

    one or more shell layers adjacent to the substrate, wherein the one or more shell layers provide mechanical stiffness and/or rigidity to the sheet in addition to any stiffness and/or rigidity provided by the substrate by itself in order to help maintain the sheet in a more rigid configuration compared to the substrate by itself and thereby facilitate passing the sheet through a shredding mechanism of a paper shredder.
