The present invention relates to a fully-biodegradable plastic masterbatch and its preparation method. Said fully-biodegradable plastic masterbatch consists of starch, coupling agent, dispersant, polycycloactone, plasticizer, anticoagulant, chemical degradation promoter and co-oxidant. Its preparation method includes steps of: (1) fining and dehydrating starch, (2) mixing, (3) extruding. Said fully-biodegradable plastic masterbatch of the present invention has fully-biodegradability, which can indeed accomplish eliminating “white pollution” and assimilate with environment, at the same time, costs low, and has good substitutability.
