A POLYOLEFIN FILM HAVING ANTIFOG PROPERTIES |
摘要 |
A multilayer, polyolefin, bi-axially oriented film comprises at least one base layer, a first intermediate layer, a first cover layer and a second cover layer disposed on the opposite side from the first cover layer and the first intermediate layer with respect to the base layer. Antifog additive is contained at least in the base layer and in the first cover . layer. In the film the ratio between the thickness of the first cover layer and the thickness of the first intermediate layer is greater than 1 and lies between 1 and 2 and the surface tension of the face of the film belonging to the first cover layer is greater than the surface tension of the other face of the film belonging to the second cover layer.
