This invention relates to a type of sunshade that has the distinctive feature of allowing sunlight and heat to pass, but prevents the passage of ultraviolet rays. The device, of conventional configuration, has a film consisting of three layers. Each layer consists of copolymers. Additives are added to these layers to absorb and stabilize ultraviolet rays. The invention allows the user, at the beach for example, to sunbathe and feel its warmth, while being protected from the damaging effects of ultraviolet rays.
