A gasket for a crown cap to be used on a carbonated beverage, especially a twist-off crown or for a bottle which is to be pasteurized, is formed of a thermoplastic material, which is preferably free of polyvinyl chloride, and which contains a hydrogenated copolymer of styrene and a conjugated diene, or a functionalized derivative thereof. The material is resistant to heat, and provides a gasket with advantageous sealing properties.
