[0021] Embodiment 1

[0022] like Figure 1 As shown, an embodiment of the utility model provides a peel-free, removable, and non-residue heat-shrinkable label, including a traceless adhesive layer 1, which is a traceless adhesive made of a polyurethane synthetic resin. The invention patent No. 201410157642.2 "A polyurethane synthetic resin for preparing a traceless adhesive sticker and a traceless adhesive sticker prepared using the same" has disclosed the formula of this traceless layer, which has the characteristics of excellent high and low temperature resistance and the like, and is not repeated here; a heat shrinkable film layer 2 is arranged above the traceless adhesive layer 1, and the heat shrinkable film layer 2 will shrink when encountering high temperature, and a printed coating 3 is arranged on the heat shrinkable film layer 2, and the traceless adhesive layer 1 is resistant to high temperatures higher than the heat shrinkable film layer 2.

[0023] Specifically, in the embodiment of the utility model, the viscosity of the side of the traceless adhesive layer 1 that is bonded to the product is lower than the viscosity of the side of the heat shrink film layer 2. The high temperature resistance of the traceless adhesive layer 1 can be selected to be between 60°C and 200°C, while the high temperature resistance of the heat shrink film layer 2 is lower than that of the traceless adhesive layer 1. For example, the high temperature resistance of the traceless adhesive is 120°C, while the high temperature resistance of the heat shrink film layer 2 is 80°C. When 100°C water is poured on the label, the heat shrink film layer 2 shrinks, and the entire label falls off from the product. The utility model provides a non-peeling, removable, and non-residual heat shrink label. The printed coating 3 is a coating that displays product information or anti-counterfeiting information. The application utilizes the principle that the heat shrink film layer 2 shrinks when encountering high temperature, and is combined with the traceless adhesive layer 1. When the label needs to be removed, it does not need to be torn by hand, but only needs to be heated, such as pouring boiling water or using a hair dryer. The heat shrink film layer 2 shrinks when heated, and the label falls off, which can avoid the need to manually remove the label, and there is no residual glue.
