A beverage closure specifically designed for carbonated soft drinks, which the manufacturer says delivers “total packaging system cost savings” by reducing closure and PET bottle finish weight has been launched by Alcoa Closure Systems International (CSI).
The 28mm Xtra-Lok mini reportedly offers many of the same features and performance found in standard size closures, but in a lower profile design. When applied to the Alcoa-designed short height bottle finish, PET bottle finish weight is reduced by 27% while maintaining the same performance parameters as previous generation bottle finishes. Inside the closure integrates Alcoa CSI's high performance XT liner, said to “maximise seal integrity and product freshness under all environmental conditions”.
