BIAXIALLY ORIENTED POLYOLEFIN FILM FOR COLD SEAL |
摘要 |
<p>The present invention relates to methods of manufacturing multi-layered polyolefin films that provide excellent adhesion to cold seal cohesive formulations. A surface of the film is discharge-treated. It has been found that when the discharge-treated surface has at least 0.3% nitrogen functional groups, it provides an excellent cold seal receptive surface. A biaxially oriented polypropylene film made according the invention may also have a second skin layer, opposite the first layer, which may be used for metallizing, laminating, or printing.</p> |
