CSI product feature

Closure Systems International (CSI) has developed a versatile, new 38mm universal light-weight closure design that is ideal for multiple filling applications and multiple bottle materials. The Extra-Lok V 38mm ODU’s advanced design is 29% lighter than competitive two-piece closures, with secure sealing on both hot-filled and cold-filled dairy and noncarbonated beverages. The unique sealing geometry of the closure adapts to a range of bottle finish e-wall thicknesses for both PET and HDPE bottles and minimizes finish distortion that can be inherent with hot-fill bottles.
