Problems solved by technology

[0003] However, in the existing rubber pressure-sensitive tapes, masking paper is often used as the substrate layer, which leads to thicker tapes, and the tapes have disadvantages such as low temperature resistance, weak toughness, and poor tensile strength.
Moreover, when the high-temperature rubber pressure-sensitive tape is wound on a round core and bent to form a tape reel, the length of the whole roll of tape is relatively short due to the large thickness of the masking paper.

Abstract

The invention discloses a PET (polyethylene terephthalate) double-sided adhesive tape. The PET double-sided adhesive tape comprises an outmost PET film layer, a middle adhesive layer and an inner substrate layer. The PET double-sided adhesive tape has advantages of freeness of adhesive residues, warping and shrinkage and high temperature resistance.

Description

technical field [0001] The invention relates to a PET double-sided adhesive tape. Background technique [0002] High-temperature rubber pressure-sensitive tape is a tape that can form a relatively strong adhesive force at high temperatures. The bonding force of high temperature rubber pressure sensitive tape is mainly van der Waals force, so after the bonding surface is formed, the structure of the bonding surface will not be destroyed. Pressure-sensitive 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 rubber pressure-sensitive adhesive tapes, textured paper is often used as the substrate layer, which leads to thicker adhesive tapes, and the adhesive tapes have disadvantages such as low temperature resist...
