ABSTRACT:
A closure or sealing element for containers, comprising a resin composition principally composed of a polyolefin resin (A) and a block copolymer (B) of a polymer block of an aromatic vinyl compound and an isobutylenic polymer block at a (A)/(B) weigh ratio within a range of 100/5 to 100/100, has so suitable pliability and excellent thermal resistance, good gas barrier properties and great oil resistance, that the closure or sealing element has good mountability onto (into) containers and excellent sealing properties of the containers in addition to good long-term shelf stability of the contents.
