The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

As shown in Figures 1 and 2, the utility model provides a double-sided adhesive tape with high and low viscosity functions, including an adhesive tape main body 1, and the adhesive tape main body 1 includes a central substrate layer 2 arranged at the center, so that The outer surface of the PET central substrate layer 2 is provided with a viscose retention layer 3, and the surfaces of the viscose retention layers 3 on both sides are respectively provided with a high viscose layer 4 and a low viscose layer 5, the high viscose layer The outer surface of 4 is provided with a high-viscosity release film 6, and the outside of the low-viscosity layer 5 is provided with a low-viscosity release film 10, and the entire double-sided adhesive tape utilizes the central base material layer 2 as the basic material, while both sides The high-viscosity layer 4 and the low-viscosity layer 5 are respectively used as a layer for pasting. Glues with different viscosities of materials can be used, or glues with the same glue ratio of materials can be used, so that the two sides of the double-sided adhesive tape have different viscosities. In specific use, choose the appropriate side to paste according to the needs, which is more practical and effectively solves the problem that the double-sided tape adopts a single stickiness, which causes too much stickiness or too little stickiness to be used. When using, you can choose the stickiness according to the usage requirements, which is more practical.
