A multilayered laminate consisting of at least two layers comprising a layer of an oriented ultrahigh-molecular polyolefin and a thermoplastic resin layer. The multilayered laminate is excellent in wearing resistance, tensile strength, impact resistance, heat sealability, and evenness of film thickness and also in the efficiency of processing. A process and apparatus for producing the multilayered laminate are also provided.
L'invention concerne un stratifié multicouche comprenant au moins deux couches dont une couche de polyoléfine orientée de poids moléculaire très élevé et une couche de résine thermoplastique. Le stratifié multicouche présente une excellente résistance à l'usure, à la traction, aux chocs; une excellente propriété de thermoscellage, et une excellente uniformité d'épaisseur de film. Ce stratifié est obtenu par un procédé d'une excellente rentabilité. L'invention concerne également un procédé et un appareil de fabrication dudit stratifié multicouche.
