Abstract
The reinforced file folder has a paper substrate which is reinforced with a breathable film having desirable properties with respect to wear. Preferably, the film is a cellulous based material adhered to the paper substrate in a manner that renders the product easily recycled. The cellulose film with a matte finished upper surface provides strong adhesion with file folder labels. The film preferably covers most of the outer surface of the front and back panels with the film applied either side of the labeling tab.
Claims17
A composite file folder comprising a front panel, a back panel and a labeling tab along one edge of said back panel with said back panel and front panel being integral along one edge with a fold axis between said panels, said folder having a paper substrate support layer with a reinforcing film adhered to exterior surfaces of said front and back panels across said fold axis and applied to each side of labeling tab, said reinforcing film being a multi-layer breathable film having a matte finish outer surface consisting of a cellulose acetate film with an underlying water based adhesive layer adhered to said paper substrate support layer, said reinforcing film covering at least 50% of an outside surface of said file folder and allowing moisture exchange from said paper substrate support layer through said reinforcing film.
A recyclable file folder comprising a paper stock substrate folded to form a front panel, a back panel and a labeling tab along one edge of said back panel, said file folder further including a cellulose based reinforcing film adhered to both a front and rear side of said labeling tab and extending over at least a border region on an exterior surface of said back panel, said reinforcing film being a breathable layer allowing moisture exchange therethrough and wherein said cellulose based reinforcing film is adhered to said paper substrate by water based adhesive.
