Closure Systems International Expands Portfolio with Launch of Omni mini XP 26mm Closure

INDIANAPOLIS--(BUSINESS WIRE)--Closure Systems International (CSI) announces the launch of the Omni mini XP 26mm closure, the company’s latest innovation in sustainable, high-performance packaging for PET non-returnable bottles. Engineered for use across carbonated cold-fill and ambient-fill beverage applications, the Omni mini XP 26mm delivers exceptional performance while achieving significant lightweighting benefits.

At just 1.8 grams, the Omni mini XP 26mm is more than 10% lighter than traditional 1881 one-piece CSD closures. When paired with a 26/22 GME 30.40 bottle finish weighing only 2.7 grams, the combined system achieves over 25% bottle finish weight reduction compared to legacy designs—substantially lowering material usage and reducing carbon footprint.

Superior Performance Across Applications
The Omni mini XP 26mm closure is designed to deliver consistent application results, reducing variability across bottling lines and minimizing defects, even at high line speeds. With best-in-class CO₂ retention (up to 4.7 volumes), the closure exceeds all global customer protocols under the broadest range of distribution and handling conditions.

Sustainable, Efficient Design

• Ultra-lightweight one-piece HDPE closure engineered for 250ml – 3L non-returnable PET bottles
• Compatible with 26/22 GME 30.40 finishes for seamless line conversions

• Made with fully recyclable polyethylene resin to support circular economy initiatives

Global Technical Support for Seamless Adoption
Backed by CSI’s worldwide network of technical service experts, the Omni mini XP 26mm ensures a smooth transition for bottlers, delivering proven performance across diverse markets and packaging formats.

“The Omni mini XP 26mm represents CSI’s commitment to advancing ultra-lightweight, sustainable closures without compromising performance,” said Clint Rush, Global Director. “By reducing both closure and bottle finish weight while maintaining industry-leading CO₂ retention and line efficiency, this innovation supports our customers’ sustainability goals and enhances their operational competitiveness.”
