ABSTRACT:
A polymer plastic cartridge for holding an information recording means is disclosed. The cartridge is comprised of a container having a writing quality-imparting layer directly embedded on a surface of the container. The writing quality-imparting layer is comprised of a matting agent, a hydrophilic polymer, and a polymer of the same type which the container is comprised of. By embedding the writing quality-imparting layer on the surface of the container it is possible to easily write on the cartridge with a pen, pencil or other conventional writing means. The writing quality-imparting layer can be easily embedded on the surface of the container and will not easily peel off.
