2622 CSD cap refers to a special plastic bottle cap for Carbonated Soft Drinks (CSD) that fits the 26/22 mm bottleneck compliant with the GME 30.40 standard. As a new-generation lightweight cap specification for carbonated beverages promoted globally by international beverage giants such as The Coca-Cola Company, it is designed to replace the traditional cap system for 28mm bottlenecks of PCO 1810/1881 standards.

II. Comparison with Traditional Specifications (PCO 1810/1881)

III. Key Features and Advantages

1. Outstanding sustainability: With a weight reduction of 0.4-0.8g per cap, an annual production capacity of 2.4 billion bottles can save approximately 331 tons of plastic material.
2. Strong compliance: Natively compatible with tethered cap design, meeting the requirements of EU SUP Directive and avoiding additional modification costs.
3. Uncompromised performance: Maintains the same sealing performance and pressure resistance as traditional caps while reducing weight, suitable for carbonated drinks with 4.3vol+ carbonation.
4. Wide versatility: Applicable to carbonated beverages, purified water, nitrogen-filled drinks and other products, achieving the "one bottle for multiple caps" model.
5. Cost-effectiveness: 30-35% reduction in raw material usage lowers production costs and improves production efficiency simultaneously.

IV. Current Status of Promotion and Application

1. Global trend: International brands like The Coca-Cola Company have widely adopted this specification in European and American markets, planning to fully implement it in China in 2025. It is expected that the transition from 1810/1881 to 2622 specification will be completed within the next three years.
2. Mature technology: Major cap equipment and material suppliers such as Berry Global, Sidel and Krones have launched supporting solutions for 2622 CSD caps.
3. Equipment compatibility: New-generation compression molding cap machines (e.g., products from Guangzhou Jingpin Intelligent Compression Molding Technology Co., Ltd.) already support the production of 2622 specification caps, and some existing equipment can be upgraded to achieve compatibility through retrofitting.

V. Conclusion

2622 CSD cap represents the development direction of lightweight and sustainable packaging for carbonated beverages. Through reduced bottleneck diameter and optimized structure, it achieves significant material savings and environmental benefits while maintaining excellent sealing performance and user experience. With the tightening of global environmental regulations and the increasing demand for corporate sustainable development, this specification is expected to become the mainstream standard for carbonated beverage packaging.
