Silicone-free release films |
摘要 |
A silicone-free release film comprises a linear ethylenic polymer having a density from 0.865 to 0.900 g/cc and an index of polydispersity of less than 5.0 and yields a maximum release force value of 39 g/cm at a film thickness of 0.10 to 0.15 mm in an adhesive peel test. The film is useful in manufacturing rolls and sheets of pressure-sensitive adhesive tape.
