Abstract
A film for molding has an annular olefin-based resin as the main component thereof and is characterized by an X surface and a Y surface both having a surface glossiness of no more than 50%, when one surface is the X surface and the other surface is the Y surface. The film has excellent winding properties during processing, has high design properties and excellent fingerprint wipe-off properties for the surface of product members (molded members after molding and decoration) when the film is used as a transfer foil for molding.
Claims7
A molding film comprising mainly a cyclic olefin-based resin, wherein
- when an X surface represents one surface of the film and a Y surface represents another surface of the film, the X surface and the Y surface both have a surface glossiness of 50% or less, and
- a ratio between thermal shrinkage in a transverse direction and thermal shrinkage in a machine direction at 80° C. satisfies −2< the thermal shrinkage in the transverse direction/the thermal shrinkage in the machine direction <−0.5.
