Carbonless copy paper (CCP), non-carbon copy paper, or NCR paper (No Carbon Required, taken from the initials of its creator, National Cash Register) is a type of coated paper designed to transfer information written on the front onto sheets beneath. It was developed by chemists Lowell Schleicher and Barry Green, as an alternative to carbon paper and is sometimes misidentified as such.
A flat push type printing paper with lock code tearable edge
The utility model relates to a flat push type printing paper with lock code tearable edge, which is made of carbonless copy paper material, characterized in that it adopts a structure scheme of one upper paper layer, 0-6 middle paper layers and one lower paper layer, and the four edges are cut flush, and the two edges are riveted with lock code and pressed with tearable lines, and the pressure-sensitive color display characteristics of carbonless copy paper are used to realize simultaneous color display of multiple paper layers in a single printing process; compared with traditional continuous format carbonless copy computer printing paper, the structure is simple, and users do not need to manually tear and separate single copies, so that the product is more convenient to use and has low cost; the self-releasing paper material with waterproof film coated on both sides of the upper paper, middle paper and lower paper can effectively prevent moisture, and is suitable for use in humid or outdoor construction.
