A multilayer paper tape including two or more paper sheets which are bonded by adhesive layers is described. Each of the top layer and the bottom layer of this stack of paper sheets and adhesive layers is an adhesive layer, around which, as a casing, is formed a folded paper sheet enclosing the stack of paper sheets and adhesive layers. This folded paper sheet is completely surrounded by an adhesive layer. A process for producing the same is also described.
