Abstract
A grinding composition for sharpening shredder blades of a shredder includes, based on total weight of the grinding composition, from 51 to 65 wt % of a grinding powder; from 5 to 35 wt % of a viscous grease agent; and from 3 to 30 wt % of at least one functional additive. A grinding sheet formed from the composition is used as a grinding product alone or in a bag. The composition is sealed in a bag and used as a grinding product. A process for manufacturing the latter grinding product employs an automatic form-fill-seal packaging machine. The shredder blades of a paper shredder are sharpened satisfactorily by the grinding composition as the grinding sheet or grinding product is shredded. The useful life of shredders is cost effectively extended while providing convenience in use that saves time and labor.
