    Abstract: Disclosed is a label 1 for battery packaging, which includes a heat shrinkable film 2, and a printed layer 3 and an adhesive layer 4 each arranged on or above the heat shrinkable film 2. The adhesive layer 4 includes an emulsive heat-sensitive adhesive containing an ethylene polymer and 10 to 30 percent by weight of a tackifier based on the total solid content. The ethylene copolymer has an ethylene content of 66 to 84 percent by weight and a melting point of 60° C. to 90° C. The heat shrinkable film 2 is preferably a film having a percentage of heat shrinkage in a main stretching direction of 10% or more after being immersed in a glycerol bath at 100° C. for five seconds. The label 1 for battery packaging excels in low-temperature tack and blocking resistance and is less likely to deteriorate with time.
