Abstract
Example embodiments relate to a disposable piping bag, having a container of polymer film. The piping bag may be made essentially from a thin-walled polymer tube, and an outwardly oriented surface of the piping bag may be provided with a rough surface structure. The rough surface structure may have the form of a pattern of raised dots or grooves presenting a surface friction coefficient which may be higher than that of the polymer film.
