[0002] The high toughness tensile resistance PET adhesive tape is a kind of adhesive tape with polyethylene terephthalate (PET) as base material, which has excellent toughness and tensile resistance. PET material itself has high strength and toughness, and through specific process treatment, it can produce adhesive tape with extremely high tensile strength and durability, which is widely used in industry, electronics, packaging and other high-demand application fields.

[0003] The high toughness tensile resistance PET adhesive tape in the prior art usually uses PET material as base material, so that the adhesive tape can achieve high toughness and tensile resistance. However, in actual use, when the gap to be pasted is long, if the adhesive tape is pasted along the gap, although the pasting effect is good and the sealing effect is good, the fixing effect on both sides of the gap will decrease, and since the pulling force comes from both sides of the adhesive tape, the tensile resistance will also decrease. If the adhesive tape is pasted vertically or obliquely to the gap, the amount of adhesive tape used will increase dramatically, and the sealing effect of pasting will decrease.

[0004] Therefore, a high toughness tensile resistance PET adhesive tape is proposed to solve the above problems. CONTENT OF THE UTILITY MODEL

If the adhesive tape is pasted vertically or obliquely to the gap, the amount of adhesive tape used will increase dramatically, and the sealing effect of pasting will decrease. A high toughness tensile resistance PET adhesive tape is proposed.
