Containers and compositions for sealing them. |
摘要 |
<p>The sealing gasket in a beer bottle is formed of a thermoplastic composition that is a homogeneous blend of 20 to 60% by weight butyl rubber and 40 to 80% by weight other thermoplastic polymer. The use of the defined gasket prevents the ingress of volatile odours from the surrounding packaging, allows venting at high pressures and provides a good barrier to oxygen, thereby leading to good storage stability of the beer.</p> |
