By controlling the initial peel strength of different pressure-sensitive adhesive layers, it can be achieved that the peel strength of the first pressure-sensitive adhesive layer is relatively low at the initial stage of bonding, which is convenient for positioning or rework. After heating or pressing, the glue of the second pressure-sensitive adhesive layer penetrates into the first pressure-sensitive adhesive layer, so that the peel strength of the tape is greatly improved, thereby achieving a fixing effect; this utility model adds a first pressure-sensitive adhesive layer with a low adhesion adhesive layer made of expanded and heat-expanded microspheres. In the initial stage of tape bonding, the peel strength is relatively low, which is convenient for positioning and timely rework of the product. After heating or pressing, the peel strength is greatly improved, thereby achieving a permanent fixing effect.
