Description

Technical Field

[0001] The utility model relates to the technical field of double-sided adhesive tapes, in particular to a double-sided adhesive tape which is convenient to cut. Background Art

[0002] Double-sided tape is a roll of adhesive tape made of paper, cloth, plastic film, elastic pressure-sensitive adhesive or resin pressure-sensitive adhesive. Double-sided tape is made of paper, cloth, or plastic film as the base material, and elastic pressure-sensitive adhesive or resin pressure-sensitive adhesive is evenly coated on the above base material to make a roll of adhesive tape. It is composed of three parts: base material, adhesive, and release paper. The tape can stick to things because there is a layer of adhesive on its surface. There are many types of double-sided tape: grid double-sided tape, reinforced double-sided tape, Rubber double-sided tape, high-temperature double-sided tape, non-woven double-sided tape, no-residue double-sided tape, cotton paper double-sided tape, double-sided glass cloth tape, PET double-sided tape, foam double-sided tape, hot-melt tape, conductive tape, PET tape, masking tape, electrical tape, high-temperature resistant tape, Mara tape, base-free tape, acetate cloth tape, PVC tape, etc., which are used in the production process of various industries.

[0003] Today's double-sided tape can basically meet people's needs, but there are still some problems. The specific problems are as follows:

[0004] 1. The problem of double-sided tape being difficult to cut. When using double-sided tape, it is difficult to cut the double-sided tape, which is not convenient to use. When the double-sided tape is cut, it may cause wrinkles on the double-sided tape, affecting the use of the double-sided tape.

[0005] 2. It is difficult to peel off the release paper from the double-sided tape. The release paper is sometimes difficult to peel off. After peeling, some release paper will remain on the double-sided tape, making the double-sided tape difficult to use. Utility Model Content
