ORIENTED POLYMERIC FILMS AND PROCESS FOR ENHANCED ORIENTATION OF POLYMERIC FILMS |
| 摘要 |
<p>Described is the presence of both a pro-rad linking agent and irradiation such as electron beam irradiation, in the manufacturing process for making an oriented, i.e. heat-shrinkable, polymeric film. The presence of both results in an amount of cross--linking that is effective to accomplish an increased orientation rate during manufacturing.</p> |
