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.

1. A disposable piping bag, comprising: a container of polymer film, wherein:the piping bag is made essentially from a thin-walled polymer tube, andan outwardly oriented surface of the piping bag is provided with a rough surface structure,the rough surface structure has the form of a pattern of dots presenting a height difference relative to portions of the polymer film surrounding said dots, said pattern of dots presenting a surface friction coefficient which is higher than that of said polymer film, andthe outwardly oriented surface of one of the piping bag includes a friction enhancing agent of a viscous high-molecular liquid. 2. The piping bag as claimed in claim 1, wherein the pattern of dots present a substantially circular perimeter. 3. The piping bag according to claim 1, wherein the thin-walled polymer tube is made of a plastic film. 4. The piping bag according to claim 3, wherein the thin-walled polymer tube is made of polyolefin plastic. 5. The piping bag according claim 1, wherein the thin-walled polymer tube is essentially transparent. 6. The piping bag according claim 1, wherein a wall of the thin-walled polymer tube includes at least two laminated material layers, an outer material layer being provided with the rough surface structure. 7. The piping bag according claim 6, wherein the rough surface structure is formed by at least one of at least partly expanding the outer material layer, at least partly starve-feeding the outer material layer, and at least partly cold-feeding the outer material layer. 8. The piping bag according claim 1, wherein the thin-walled polymer tube has a severance mark that is transversal to a longitudinal direction of the thin-walled polymer tube. 9. The piping bag according claim 8, wherein the thin-walled polymer tube has a joint that is parallel to the severance mark. 10. The piping bag according claim 9, wherein the joint is a welding joint. 11. A blank for manufacturing at least two disposable piping bags, each disposable piping bag, comprising: a container of polymer film, wherein:the blank includes of an elongated thin-walled polymer tube, the piping bags are detachable from one another by a severance mark,an outwardly oriented surface of the thin-walled polymer tuber is provided with a rough surface structure,the rough surface structure has the form of a pattern of dots presenting a height difference relative to portions of the polymer film surrounding said dots, said pattern of dots presenting a surface friction coefficient which is higher than that of said polymer film, andthe outwardly oriented surface of one of the piping bag includes a friction enhancing agent of a viscous high-molecular liquid. 12. A method of manufacturing a disposable piping bag including a container of polymer film, comprising: forming the piping bag essentially from a thin-walled polymer tube;providing an outwardly oriented surface of the thin-walled polymer tube with a rough surface structure in a form of a pattern of dots presenting a height difference relative to portions of the polymer film surrounding said dots, said pattern of dots presenting a surface friction coefficient which is higher than that of said polymer film; andadding a friction enhancing agent of a viscous high-molecular liquid to an outwardly oriented surface. 13. The method according to claim 12, wherein providing the outwardly oriented surface with the rough surface structure comprises adding grains or flakes to the material of which the thin-walled polymer tube is made. 14. The method according to claim 12, further comprising forming the thin-walled polymer tube by laminating at least two material layers, an outer material layer being provided with the rough surface structure. 15. The method according to claim 14, wherein providing the outwardly oriented surface with the rough surface structure comprises at least partly expanding the material of which an outer layer of the thin-walled polymer tube is made, at least partly starve-feeding the material of which an outer layer of the thin-walled polymer tube is made, and at least partly cold-feeding the material of which an outer layer of the thin-walled polymer tube is made.
