The surface layer of the tape carrier base paper should not only have good adhesion with the upper sealing tape, but also have good interlayer adhesion with the middle layer of the tape carrier. Therefore, the requirements for the tensile strength of the surface layer, the smoothness and surface strength of the surface layer are relatively high.

The surface layer is usually made of kraft coniferous wood pulp and kraft broad-leaved wood pulp, with a ratio range of (40 ~ 70): (60 ~ 30). The beating methods are mostly sticky beating combined with free beating, and the beating degree is controlled at 40 ~ 55 ° Sr.
