CONTAINER CLOSURE WITH A SEALING ELEMENT

Abstract:

The invention relates to a container closure (1, 21, 41, 61) with a sealing element (3, 23, 43, 63). The sealing element (3, 23, 43, 63) comprises a polymer composition. The polymer composition comprises a butene copolymer. The butene copolymer has a melting temperature T.sub.m of between 30.degree. C. and 130.degree. C., wherein the melting temperature T. is determined by the second heating curve of a DSC measurement at a heating rate of 10.degree. C. min.sup.-1
