  • Patent number: 10106659
    Abstract: A molding film is high in both windability during film production and also excellent in appearance quality and moldability. The molding film includes cyclic olefin based resin, has roughened regions in side edge parts of the molding film, is non-oriented, and satisfies (1) to (3): (1) one of the surfaces has a surface roughness SRa of 2 nm or more and 30 nm or less in the central region, which is defined as the region outside the roughened regions, whereas the other surface has a surface roughness SRa of 100 nm or more and 800 nm or less, (2) the ratio h/t where h represents the height (in ?m) of the roughened regions while t represents the thickness (in ?m) of the central region is 5/100 or more and 30/100 or less, and (3) the width of the roughened regions is 5 mm or more and 20 mm or less.

  • Patent number: 9649829
    Abstract: The present invention provides a film for forming which exhibits both excellent dimensional stability in processing and excellent formability as well as excellent appearance of surfaces and can thus be suitably applied to a variety of forming members through forming and used in forming decoration applications. Provided is a film for forming comprising a cyclic olefin-based resin as a main component, wherein the storage modulus at 120° C. is 101 MPa to 3,000 MPa and the storage modulus at 170° C. is 100 MPa or less.

  • Patent number: 6797381
    Abstract: A polymer film characterized in that the Poisson's ratio of the longitudinal direction (MD) to the transverse direction (TD) is less than 0.4. This film exhibits superior dimensional stability under high tension, cause almost no reading errors when it is used in a magnetic recording medium, and provides a high-capacity magnetic recording medium having superior electromagnetic conversion characteristics.

  • Patent number: 5654394
    Abstract: A thermoplastic resin film wherein the variation in thickness of the film in the longitudinal direction is not more than 5% and the ratio "Pw1/PwT" of the sum of spectral intensities of wave-number components present in the wave-number range of 0.15 to 0.45 (1/m) (Pw1) to the sum of spectral intensities of the full wave-number range (PwT) determined when a wave form of the variation in thickness is subjected to analysis of Fourier transformation is not more than 0.20, and wherein the variation in thickness of the film in the longitudinal direction is not more than 5% and the ratio "Pw2/PwT" of the sum of spectral intensities of wave-number components present in the wave-number range of 1.00 to 2.00 (1/m) (Pw2) to the sum of spectral intensities of the full wave-number range (PwT) is not more than 0.15. In such a film, the uniformity in thickness can remarkably improved, and snaking and wrinkles in post processing can be prevented.
