A dual-layer label

A double-ply label is separated into an up layer and a down layer, which is characterized in that the down layer of the label is divided into two areas, wherein one area is printed with peculiar information of the commodity and the other area is a blank area. The up layer has the same size of the blank area and is printed with public information. The label of the up layer includes a transparent portion used to cover the area printed with peculiar information of the commodity of the label of the down layer. The similar product label composed of the double-ply label can form different homogeneous labels by changing the peculiar information of the commodity on the up layer. The utility model has the advantages of convenient making, forming a wild variety of similar labels by replacements and avoiding the resource waste of too much printing on one layer of the label as before.
