1. A method for manufacturing an eco-friendly antibacterial polymer-coated paper, the method comprising:
mixing 40 to 50% by weight of a mixture of methyl methacrylate and butyl acrylate as acrylic monomers in a weight ratio of 1:4 to 4:1, 0.5 to 3.0% by weight of a copper nanopowder, 0.5 to 2.0% by weight of an initiator, 1 to 5% by weight of a polymeric dispersant, and a balance of water to prepare a mixed solution;
stirring the mixed solution at 70 to 80° C. for 5 to 10 hours for polymerizing the mixture and thereby forming a polymeric coating agent; and
coating the polymeric coating agent to a thickness of 5 to 10 μm on a paper and drying the polymeric coating agent.
