    摘要: Multilayer laminate film obtained by alternately laminating first and second layer. The two layers comprises respectively two different crystalline thermoplastic resins. The maximum light reflectance of the wavelength region 350-2000nm is higher than that of a base-line obtained from the light reflectance curve in the same wavelength range. Multilayer laminate film is obtained by alternately laminating first and second layer so that >=11 layers are formed and biaxially stretching. Each layer has a thickness of 0.05-0.5mu m. The first layer comprises a crystalline thermoplastic resin, and the second layer comprises a crystalline thermoplastic resin of composition different to the first layer. The maximum light reflectance of the wavelength region 350-2000nm is >=20% higher than that of a base-line obtained from the light reflectance curve in the same wavelength range. Many melting points measured by differential scanning calorimetry, are present and the temperature difference of each melting point is >=5[deg]C. At least one crystallization peak measured by differential scanning calorimetry is present. An independent claim is also included for the manufacture of a biaxially stretched multilayer laminated film by forming a sheet by alternately laminating a crystalline thermoplastic resin for a first layer and a crystalline thermoplastic resin for a second layer with a melting point >=15[deg]C lower than the first layer to give >=11 layers, 2-50 times stretching in the film-forming direction and the width direction, and heat fixing in the range from 10[deg]C lower than the melting point of the second layer to a temperature 15[deg]C lower than the melting point of the first layer.

    摘要: Use of a splinter binding and weight bearing foil 2 with an adhesive 3 and a glass pane 4 in a smoke barrier system 1. The smoke barrier system 1 comprises a fixation element 5. The adhesive 3 is arranged between the splinter binding foil 2 and the glass pane 4, wherein the splinter binding foil 2 is equipped to hold glass fragments of a glass pane 4 together in case of a glass breakage. The splinter binding foil 2 is arranged between the fixation element 5 and the glass pane 4, in particular the splinter binding foil 2 is clamped between the fixation element 5 and the glass pane 4. The splinter binding foil 2 is designed to detach from the glass pane 4 in the case of fire and/or temperature influence.
