    • The invention relates to a multi-layered film, particularly in the form of a hose-shaped outer film (2) for an insert hose (1) of a pipe rehabilitation system. The film in accordance with the invention is characterized by the fact that, on the one hand, silver-colored pigments are inserted in at least two layers (2a, 2e) of the film (2), or in each case, a metallization is applied on both outer layers of the film (2), or silver-colored pigments are inserted in at least one layer of the film (2) and a metallization is applied on an outer layer of the film, and that, on the other hand, at least one UV absorber is inserted in at least one or several layers (2b, 2d) of the film (2), such that, in harmonization with the film thickness and the overall thickness of the film (2), the entire film (2) is permeable for UV light and visible light in a wavelength range from 200 to 800 nm at a rate of less than 0.1% and is perceived by a viewer as opaque, non-transparent and obscure, and the UV radiation and visible radiation are reflected in a wavelength range from 200 to 800 nm, in particular from 300 nm, at a rate of more than 20%. The invention also relates to an insert hose with such a film and its use.
    • 本发明涉及一种多层膜,特别是用于管道修复系统的插入软管(1)的软管形外膜(2)的形式。 根据本发明的膜的特征在于,一方面,银色颜料插入到膜(2)的至少两层(2a,2e)中,或者在每种情况下,金属化是 施加在膜(2)的两个外层上,或银色颜料插入到膜(2)的至少一层中,并且金属化被施加在膜的外层上,另一方面 至少一个UV吸收剂被插入到膜(2)的至少一个或多个层(2b,2d)中,使得在与薄膜(2)的膜厚度和总厚度一致的情况下,整个薄膜 (2)可以以低于0.1%的速率在200至800nm的波长范围内对UV光和可见光透过,并且由观察者感知为不透明,不透明和不透明的UV辐射和可见光辐射 以大于20%的速率在200至800nm,特别是300nm的波长范围内反射。 本发明还涉及一种具有这种膜的插入软管及其用途。
