摘要:
The invention provides a plastic film possessing improved permeability to water vapor and high heat shielding property. Said plastic film is characterized by water vapor permeability of 100 to 25,000 g/m.sup.2 /24 hr, light transmittance of 20 to 95% and infrared transmittance of 5 to 90% and made of at least one material selected from a group comprising polyetherpolyamide block copolymer, thermoplastic polyester elastomer and thermoplastic polyurethane and containing flat inorganic particles coated with a substance having high refractive index.
