Abstract
The present invention relates to compositions (compounds) which can be used as seal material in vessel caps, even under pasteurization conditions and possibly sterilization conditions. More specifically, the invention relates to such compositions that are suitable for vessel caps that can be unscrewed, such as lug screw caps and in particular Press-on/Twist-Off® caps, and that result in a reduced migration of undesirable substances.
