摘要:
An object of the present invention is to provide a film having a high brightness and a natural metal-effect, and also having excellent formability, causing no delamination and maintaining the metal-effect after forming. Another object is to provide a molded body having less environmental burden, excellent in recycling efficiency and giving no electromagnetic interference.
A laminated film including a structure where each 30 layers or more of a layer composed of a resin A (A layer) and a layer composed of a resin B (B layer) are alternately laminated, wherein a relative reflectance in a wavelength range of 400 nm to 1000 nm is 30% or more, tensile stresses at 100% elongation in a longitudinal direction and a width direction of the film are 3 MPa or more and 90 MPa or less in a tensile test at 150°C, and the number of layers with a layer-pair thickness of 10 nm or more and less than 220 nm is more than the number of layers with a layer-pair thickness of 220 nm or more and 320 nm or less.
