Biodegradable bioplastic food contact service items are formed of a high biomass content bioplastic compound. Preferred embodiments of biodegradable bioplastic food contact service items each comprise a thermoplastic matrix that includes a main thermoplastic medium and a matrix material ingredient. The main thermoplastic medium is a combination of three synthetic polymers that form a functional material component into which biomass material can be blended. The three synthetic polymers are polypropylene, ultralow molecular weight polyethylene, and low density polyethylene; and the matrix material ingredient includes a polysaccharide compound in an amount of at least 50 percent by weight. Exemplary embodiments of the food contact service item use corn starch as a preferred polysaccharide compound.
