Abstract: A multilayer film including a first outer layer containing 70 to 30% by mass of a propylene homopolymer (A) and 30 to 70% by mass of a propylene/ethylene random copolymer (B) having an ethylene content of 5% by mass or less, an inner layer containing a propylene/ethylene block copolymer (C) and an ethylene/propylene copolymer elastomer (D), and a second outer layer containing 70 to 30% by mass of the propylene homopolymer (A) and 30 to 70% by mass of the propylene/ethylene random copolymer (B) having an ethylene content of 5% by mass or less, in that order.

Abstract: A support film for tape which is used for a tape, the support film for tape includes: a film-shaped support formed of polyurethane; and a barrier layer which includes a water-soluble polymer compound and montmorillonite and is formed on one surface of the support. The support film for tape has a percentage content of the montmorillonite in the barrier layer is equal to or more than 2 percent by weight and equal to or less than 22 percent by weight.

Abstract: A support film for tape which is used for a tape includes a film-shaped support formed of polyurethane, a barrier layer which includes polyvinyl alcohol and a layered inorganic compound and is formed on a surface of the support, and an undercoat layer which is disposed between the support and the barrier layer, and which causes the support and the barrier layer to adhere to each other.

Abstract: The present invention provides a release film which has a release layer on a film substrate, which has excellent long-term preservation stability and yet maintains a stripping performance of the release film, which serves to make inspection for foreign materials easy, and which provides excellent design effect when a print layer is formed. The release film has average luminous reflectance of the release film on the surface of the side on which the release layer is formed being in the range of 0.5-2.5%, spectral reflectance curve of the release film surface on which the release layer is formed having a local minimal value and no local maximal value in the wavelength region in the range of 400-800 nm, reflection hue of the release film on the side on which the release layer is formed satisfying both ?8?a*?8 and ?16?b*?8 in the L*a*b* color coordinate system.
