Problems solved by technology

[0003] However, in the existing cold-pressed tapes, kraft paper is often used as the base layer, which leads to thicker tapes, and the tapes have disadvantages such as weak toughness and poor tensile strength.
Moreover, when the cold-pressed tape is wound on a round core and bent to form a tape reel, the length of the entire roll of tape is shorter due to the greater thickness of the kraft paper

Abstract

The invention relates to a tape, in particular to a self-adhesive tape with improved performance and an improved structure. The cold-pressed self-adhesive tape comprises a PET (polyethylene terephthalate) film layer, a bonding agent layer, a cotton paper layer and an emulsion layer sequentially from top to bottom. The cold-pressed self-adhesive tape which adopts the PET film as a substrate layer and has superior tensile strength and good toughness is provided.

Description

technical field [0001] The present invention relates to adhesive tapes, in particular to a self-adhesive tape with improved performance and structure. Background technique [0002] Cold-pressed self-adhesive tape is a kind of relatively strong adhesive force that can be formed under a small force. The adhesive force of the self-adhesive tape is mainly van der Waals force, so after the bonding surface is formed, the structure of the bonding surface will not be destroyed. Self-adhesive tape is a kind of tape that is sensitive to pressure, does not require heating, does not require solvents, does not require high pressure, and can be bonded with a little pressure or with a finger. Its characteristics are easy to stick, not difficult to remove, and peel without damage. [0003] However, in the existing cold-pressed adhesive tapes, kraft paper is often used as the substrate layer, which leads to thickening of the adhesive tape, and the adhesive tape has disadvantages such as we...
