Silgan Closures launched the latest generation of ELC gable top caps: the ELC 30 L. Designed for cartons of all formats and sizes from 28- to 35-mm, the ELC eliminates the pull ring in favor of a drop-down tamper band, providing visual, audible and tactile tamper evidence. On a standard bottle finish, the A retaining bead is a rigid ring and the flexible J-band on the closure snaps under the A-bead during application. This standard design does not work on fitments due to the rigid A-bead on the finish causing damage to the tamper band bridges during application, the company explains. Silgan’s patented design flips the J-band from the closure and puts it onto the finish using segmented flights. This creates a flexible A-bead on the finish, eliminating broken bridges. ELC technology takes away the need for a removable pull ring. The tamper evidence of the pull ring is replaced with the traditional drop-down tamper band on the outside of the finish, allowing a one-step opening, it adds. ELC’s thin-walled bore seal within the cap is angled slightly downward and flexible, guiding the valve seal into the bore during capping. The flights keep caps aligned on cartons during production. The double seal points provide oxygen transmission rates as efficient as the ring pull membrane. At 1.90 grams, the ELC 30 L is one of the lightest weight fitments on the market, the company says.
