Polymere Zusammensetzungen und ihre Anwendung für Behälterverschlüsse.
摘要
A sealing composition for a container closure comprises a polymeric matrix material and is modified by the inclusion therein of an oxygen scavenger. The composition can be in fluid or meltable form ready for application to a closure or it can be present as a deposit on the closure, for instance a gasket around the closure. Preferably the scavenging properties of the deposit are activated by pasteurising or sterilising the deposit when sealing a container with the closure. The invention is of particular value when the closure is a metal cap for a beer bottle.
