REINFORCED FILE FOLDER AND METHOD |
摘要 |
<p>A file substrate of paper stock such as a file backer or file folder having a reinforced edge portion is disclosed. Such file substrate has at least one straight edge with a tear resistant plastic film secured either side of the substrate and about the straight edge. This film reinforces the substrate straight edge without significantly increasing the thickness thereof. 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.</p> |
