ABSTRACT:
A method of forming a folder of documents and a folder for putting the method into effect. The folder has folds or creases defining a spine between a front and a back cover of the folder, and side folds spaced from the spine folds. An adhesive strip covered with a protective film is applied to the interior of the folder along the spine in a region delimited by the side folds. In use the protective film is removed, a sheaf of documents, preferably stapled together, is permanently secured in the folder so that documents cannot be removed without detection.
