積層フィルム
Document Type and Number:
Japanese Patent JP7020486
Kind Code:
B2
Abstract:
A layered film (100) includes, in order, a first skin layer (110) formed from a thermoplastic resin S1, a core layer (120) formed from a thermoplastic resin C, and a second skin layer (130) formed from a thermoplastic resin S2. The first skin layer, the core layer, and the second skin layer have a specific relationship in the average absorption rate of light in a wavelength region of 9-11 μm. The glass transition temperature Tg(s1) of the thermoplastic resin S1 is 150°C or higher, the glass transition temperature Tg(s2) of the thermoplastic resin S2 is 150°C or higher, and the UV transmittance at a wavelength of 380 nm is 10% or lower.
