    摘要: The present invention relates to compositions (compounds) which can be used as seal material in vessel caps under sterilization conditions. More specifically, the invention relates to such compositions that are suitable for vessel caps or vacuum caps that can be unscrewed, such as cam screw caps and in particular Press-on/Twist-off® caps, and that demonstrate a reduced migration of undesirable substances.
