Alcoa closures seal up carbonated, malt beverages

Alcoa Closure Systems International (CSI) has developed the first short-height closures—the 28 millimeter Xtra-Lok mini and 28 millimeter MB-Lok mini—for multi-serve PET package sizes up to 2.5 liters.

The products provide beverage customers the capability and advantage of using one closure design for all of their PET bottle requirements. In addition to reduced inventory, the new closures provide significant packaging cost savings and environmental benefits.

Alcoa CSI has developed proprietary technology along with its proven XT liner that enables the new closures to withstand the most stringent packaging conditions for product safety and carbonation retention, while maintaining an easy-open, attractive appearance. This capability allows bottling operations to source one closure for both single-serve and multi-serve packages. The result is reduced closure inventory, fewer equipment changeovers and higher operational efficiencies.
