Seals made of a multi-layered material for sealing means, particularly a sealing capsule

摘要

A seal particularly for a wine bottle screw cap includes a compressible base layer C of an expanded polyolefin, a support layer S and an oxygen barrier layer B on the support layer S. The layer B can be between the layers C and S, or the layer S can be between the layers C and B. In either case the layer B or the layer S are intended to be in contact with the wine in the bottle.
