<p>An inexpensive, easy-to-produce, adhesive-coated polyolefin ribbon or the like is provided which has desirable remoistenability and excellent peel strength characteristics, notwithstanding elimination of the need of physically treating the polyolefin substrate prior to adhesive coating by methods such as chemical etching or other means of surface abrading. A primer layer is applied and bonded directly to the polyolefin ribbon without any preliminary treatment thereof, and a remoistenable adhesive layer containing polyvinyl alcohol is applied over the primer layer and bonded thereto to complete the ribbon. In preferred forms, the primer layer includes respective quantities of ethylene vinyl acetate and chlorinated polyolefin material, and this has been shown to synergistically bond to both the substrate and polyvinyl alcohol remoistenable adhesive applied thereover. A method of producing the ribbon is also provided and includes the steps of sequentially applying and drying the initially liquid primer and adhesive layers to the substrate to present the final remoistenable ribbon product.</p> |
