Antibacterial boards

Abstract

This invention provides an antibacterial board material comprising a board material and a functional film layer. The board material has a plurality of surface regions respectively located on its surface, and the functional film layer covers each of the surface regions of the board material, each having an adhesive carrier and a plurality of antibacterial substances located within the adhesive carrier. Thus, the functional film layer itself acts as a temporary carrier, contact, and delivery medium for the antibacterial substances, ensuring that even after the functional film layer is torn off, removed, or removed, the antibacterial substances remain in the surface regions, thereby allowing the antibacterial board material of this invention to retain its antibacterial effect.
