An important new development in closure technology is the composite closure. Defined as a two-piece cap comprising a central metal disk & plastic outer ring, composite closures can be pivotal in the creation of effective & elegant packaging. These innovative closures combine the strengths of metal & plastic to offer superior barrier performance, as well as easier opening. Safety with composite caps is twofold. The first layer of safety is the traditional & reassuring "pop" button on glass containers. It also has an emotional connection that immediately conveys security, product freshness & quality. The plastic ring provides a second level of protection with a tamper-evident drop-down band that separates before the metal disk seal is broken.
