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.

A closure plug of a battery includes an external thread for installing into an opening of a battery cover, and at least one gas-tight seal arranged on an outer side of the closure plug. The at least one gas-tight seal includes a mixture of polypropylene or polyethylene and polyisobutylene.

A simulated sealant which comprises a polybutene resin and a polyethylene resin, wherein the polyethylene resin is in a sol state and is dispersed in the polybutene resin.

The present invention provides a sealing resin composition containing a polyester resin (A), carbodiimide (B) and an antioxidant (C).
