Abstract

The present invention provides a liner (20) for a closure (10). The liner (20) comprises an ethylene and vinyl acetate copolymer, or an ethylene and vinyl acetate copolymer and an ionomer, and the liner (20) resists scuffing and stringing. The present invention also provides a closure (10) comprising a top wall (14) having an interior surface (14a) and an exterior surface (14b), a peripheral skirt (16) disposed about said top wall (14) and circumscribing the interior surface (14a), means on the skirt (16) for attaching the closure (10) to a container, and a sealing liner disposed on the interior surface of the top wall, the sealing liner (20) comprising an ethylene and vinyl acetate copolymer, or an ethylene and vinyl acetate copolymer and an ionomer.
