Cross-linked multilayer heat-shrinkable oriented polymeric film |
摘要 |
Described is the presence of both a chemical cross 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.
