Abstract: Proposed is a transparent plastic sheet for blocking ultraviolet and infrared rays, the sheet including a base layer including a thermoplastic polymer and a skin layer provided on one or each side of the base layer and including a thermoplastic polymer, a ultraviolet blocking agent, an antioxidant, and an infrared blocking agent, in which the base layer and the skin layer are formed by a co-extrusion method.

Abstract: Disclosed is a bulletproof panel that can replace glass of a vehicle, an elevator, a meeting room, a ticket booth, or the like. The bulletproof panel includes a base layer, a reinforcing layer provided on each of opposite sides of the base layer, and an adhesive layer provided on the base layer and each of the reinforcing layers and made of a UV-curable urethane resin. The bulletproof panel is characterized in that when the panel is impacted by a bullet, the base layer breaks and absorbs a rotational force of the bullet, while the reinforcing layers provided on respective opposite sides of the base layer suppress broken pieces of the base layer from scattering. Thus, the bulletproof panel can exhibit an excellent bulletproof effect because the bullet is fixed in the base layer and does not penetrate therethrough, while preventing broken pieces generated by the bullet from scattering.
