The width of the strip (5) is such that the holes are arranged within the strip. The polymer coating is arranged on one or both sides of the sheet. The strip is obtained by applying a polymer film. The polymer coating consists of polyethylene terephthalate or polyethylene. An independent claim is also included for a method for finishing a folder punch hole on a sheet-like ring binder insert.
