PROBLEM TO BE SOLVED: To obtain a peelable thermosensible label which controls the change of adhesive strength with the passage of time and can be peeled off easily even after the elapse of a long period and a container with the label. SOLUTION: The peelable thermosensible label has a label base material, a printing layer, and a thermosensible adhesive layer. The thermosensible adhesive contains a polyolefin as the main component of a base polymer, and the content of a tackifier in the adhesive is below 10 wt.% of the total weight of the base polymer. The melt flow rate at 230°C and under 2.16 kg load of the adhesive is 5-40 g/10 min. The label is attached to the container. COPYRIGHT: (C)2004,JPO
