Onionskin or onion skin is a thin, lightweight, strong, often translucent paper, named for its resemblance to the thin skins of onions. It is typically 25–39 g/m2 and may be white or canary-colored. Onionskin paper was usually used with carbon paper for typing duplicates in a typewriter where low bulk was important. It is also used for toy kites and advanced paper airplanes due to its durability for its weight, and in traditional cel animation due to its translucency.
