PROBLEM TO BE SOLVED: To obtain a readily unsealable sealing material having excellent sealing properties and unsealing properties to a polyethylene, especially a polyethylene surface of a paper coated with a polyethylene. SOLUTION: This polymer composition is characterized in that the polymer composition comprises 45-80 wt.% of an ethylene/unsaturated carboxylic acid copolymer having 4-20 wt.% unsaturated carboxylic acid content or its ionomer (A), 3-15 wt.% of a polymer (B) comprising propylene as a main component, 5-25 wt.% of a polymer (C) comprising 1-butene as a main component and 3-15 wt.% of wax (D). |
