The present invention relates to a method for manufacturing a plastic screen for an electronic bulletin board capable of easily facilitating writing and removing with a water-based pen on a front surface in a public office, a school, an institute, and a convention center; lecturing and storing by being connected to a computer; and enabling the lecturing with video data such as an image or a video by using a beam projector in a specific space where many people gather. A plastic screen for an electronic bulletin board comprises a base layer composed of resin, a screen layer provided on the base layer, and a matte polypropylene (PP) layer provided on the screen layer. The screen layer includes a pigment, a flame retardant, an anti-static agent, a UV stabilizer, and resin. The base layer, the screen layer, and the matte polypropylene layer are integrated by multiple extrusion molding. The multiple extrusion molding is performed by a matte roller. The present invention easily facilitates the writing and removing with the water-based pen, and enables the lecturing and storing by being connected to the computer.(S10) Prepare a pigment, a flame retardant, an anti-static agent, a UV stabilizer, and resin(S20) Prepare the resin(S30) Prepare matte PP(S40) Pellet molding(S50) Triple pressing(S60) Vertical and horizontal stretching(S70) WindingCOPYRIGHT KIPO 2018
