BIAXIALLY ORIENTED POLYOLEFIN FILM FOR COLD SEAL |
摘要 |
<p>The present invention relates to multi-layered polyolefin films that provide excellent adhesion to cold seal cohesive formulations. In a preferred embodiment, a film of the present invention is characterized as having a polyolefin resin layer with a discharge-treated surface on one side. 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 of the present invention may also have a second skin layer, opposite the first layer, which may be used for metallizing, laminating, or printing.</p> |
