The utility model provides a there is not plastify sticky tape of degradable, as shown in figure 1, including paper tape layer 1, enhancement layer 2, first viscose layer 3, enhancement layer 2 is fixed between paper tape layer 1 and first viscose layer 3, enhancement layer 2 is network structure (cotton) woven by degradable fiber line. The paper tape layer 1 is kraft paper having a silicone oil layer 11 on one side.

Optionally, the adhesive tape further comprises a second adhesive layer 4, and the reinforcing layer 2 is adhered to the paper tape layer 1 through the second adhesive layer 4.

Optionally, the first adhesive layer is selected from one of cotton paper adhesive or non-substrate adhesive, and the second adhesive layer is selected from one of cotton paper adhesive or non-substrate adhesive.

In particular, the degradable fiber thread is cotton thread or recycled cotton thread.

The preparation process of the degradable plastifying-free adhesive tape provided by the embodiment of the utility model is as follows:

step 1: as shown in fig. 6, the first adhesive layer 3 with the release layer 6 is adhered and fixed to one side of the reinforcing layer 2;
