The invention provides an anti-penetration paper-based
adhesive tape. The anti-penetration paper-based
adhesive tape sequentially comprises a surface treatment layer, a paper substrate layer, a pressure-sensitive
adhesive layer A, a PET film layer and a pressure-sensitive adhesive layer B. According to the anti-penetration paper-based adhesive tape provided by the invention, through
embedment of the PET film layer between the paper substrate layer and the adhesive layer, the problems that during paint spraying and brushing or long-time use of a
solvent on the back side of the adhesive tape, the
solvent penetrates and adhesion of adhesive to paper is affected after
solvent penetration, and during peeling again, the adhesive remains on the surface of an adhered object and the solvent causespollution and loss to the surface of the adhered object after penetration into the surface of the adhered object can be effectively improved; the PET film layer also can enhance the strength and the
toughness of the paper, so that the paper does not break when applied to a large bent position and a corner; meanwhile, adhesion of the paper to a substrate can be enhanced; the surface of a paper material is generally an uneven porous surface and the adhesive difficultly completely penetrates therein, so that during using, point-type and sheet-type adhesive failure is easily caused; when PET is used as a carrier, the PET has relatively
high surface energy and a
smooth surface and has excellent bonding to the adhesive, so that the problems such as the adhesive failure and adhesive residual areavoided.
