A substrate strip is provided on at least one face with a coating of hot-melt adhesive containing an odor-control powder of clay, zeolite, cyclodextrin, or a combination thereof incorporated into the adhesive in a grammage of at least 0.1% to 10% by weight based on a total mass of the adhesive to form an adhesive tape. This tape is then wrapped around a plurality of cables in an automobile.

Provided in the present application is an identifiable substrate, including a base film and a marking layer, the base film including an identifying surface, the marking layer is an ink coating, in which the marking layer is laminated with the identifying surface of the base film; a surface tension of the identifying surface is D1; a surface tension of the marking layer is D2; and a thickness of the marking layer H satisfies 0.8 ?m?H?(D1/D2)?5 ?m. In the present solution, the relative surface tension of the base film and the marking layer reflects the surface effect of the lamination between the base film and the marking layer. A thickness range of the marking layer is determined based thereon, so that the ink load on the surface of the base film is effectively controlled within the threshold value of the base film.
