Ideal closure® offers superior barrier performance, good abuse resistance, easier opening and brand differentiation on the retail shelf. Compatible with glass and plastic containers, the ideal closure® is a unique hybrid of a plastisollined metal disk and a plastic band. The metal disk forms an airtight seal against the container to prevent oxygen ingress while the consumerfriendly plastic band provides for easy opening. The plastic band includes a perforated ring, which breaks before the seal to provide clear tamper evidence.
