ABSTRACT A folder having a reinforced side tab for use in a lateral file system is disclosed. The folder comprises a rectangular blank to be folded in forming the folder. A side of the blank includes a projection to provide the side tab when the blank is folded to make the folder. The projection forms an undercut on a side of the folder when the blank is folded. The blank in the area of the undercut is reinforced on both surfaces of the blank by securing to both surfaces a high tensile strength tear resistant reinforcing film. This minimizes tearing of the folder in the area of the undercut during use of the folder in a lateral file system. A coloured adhesive may be used for securing a clear reinforcing film to the folder. This provides a colour band down a side of the folder to distinguish a group of files in a file system. Method and apparatus are disclosed for applying the reinforcing film to file folder blanks.
