Title
(EN) MULTILAYERED STRETCHED RESIN FILM
(FR) FILM DE RESINE ETIRE MULTICOUCHE
Abstract
(EN)
A multilayered stretched resin film characterized in that it comprises a front-side layer (A) which is printable and comprises a thermoplastic resin and inorganic fine particles and/or an organic filler and superposed on the back side of the layer (A) a back-side layer (B) comprising one or more thermoplastic resins comprising a hydrophilic thermoplastic resin and surface-treated inorganic fine particles, and that the back-side layer (B) has a peel strength of 10 to 200 g/cm. The multilayered stretched resin film is excellent in printability and suitability for embossing. It can be directly applied to, e.g., a wall with an aqueous adhesive without the need of backing with natural paper unlike conventional wall papers. When stripped from the wall surface, the film can be recovered in an easily recyclable state.
(FR)
L'invention concerne un film de résine étiré multicouche caractérisé en ce qu'il comporte une couche avant (A) imprimable et contenant une résine thermoplastique, de fines particules inorganiques et/ou une charge organique, une couche arrière (B), superposée sur l'arrière de la couche (A), contenant une ou plusieurs résines thermoplastiques constituées d'une résine thermoplastique hydrophile et de fines particules inorganiques traitées en surface, et en ce que la couche arrière (B) présente une résistance au pelage de 10 à 200 g/cm. Ce film de résine étiré multicouche est excellent en matière d'aptitude à l'impression et au gaufrage. Il peut être appliqué directement p. ex. contre un mur au moyen d'un adhésif aqueux, sans qu'un renforcement à l'aide de papier naturel ne soit nécessaire, contrairement à des papiers peints classiques. Lorsqu'il se décolle de la surface murale, ce film peut être récupéré de manière facilement recyclable.
