1. An aquatic plant biomass-based decomposable and antibacterial plastic masterbatch composition consisting of:
15 wt % to 60 wt % of environmental biodegradable polymer materials, the environmental biodegradable polymer materials being selected from at least one of natural polymer materials, microbial synthetic polymer materials, chemically synthesized polymer materials and a combinations thereof;
30 wt % to 80 wt % of aquatic plant fiber material, and the aquatic plant fiber material being selected from fibers extracted from seawater algae and/or freshwater algae;
2 wt % to 15 wt % of natural decomposable macromolecular antibacterial materials, and the natural decomposable macromolecular antibacterial materials being selected from chitosan and/or alginic acid;
2 wt % to 10 wt % mineral fillers;
0.5 wt % to 5 wt % dioctyl adipate (DOA);
0.1 wt % to 2 wt % 1,1,1-Trimethylolpropane (TMP); and
0.3 wt % to 2 wt % of silane coupling agent.
