Advanced Bimodal Polyethylene Grade Supports High-Speed Production, Reliable Sealing, and Improved Beverage Packaging Quality
Russia’s leading polymer producer, SIBUR, has introduced HD21550 CC, a new bimodal high-density polyethylene (HDPE) grade developed specifically for manufacturing 38 mm beverage closure caps used on juice, dairy, tea, and other beverage containers. The new material is designed to help packaging manufacturers improve production efficiency while delivering superior cap performance and product protection.
HD21550 CC is suitable for both injection moulding and compression moulding, offering processors greater manufacturing flexibility. The new grade was engineered to meet the increasing demands of closure manufacturers, where stable processing on high-speed production lines, consistent geometry, dependable sealing, and compliance with stringent hygiene standards are essential.
The bimodal polyethylene technology combines excellent processing characteristics with high mechanical strength, enabling closure caps to maintain their shape during transportation and storage while providing reliable sealing throughout a beverage’s shelf life. According to SIBUR, the material also meets strict organoleptic requirements, ensuring it does not alter the taste or aroma of packaged beverages.
Developed by scientists at SIBUR PolyLab Moscow in collaboration with specialists from ZapSibNeftekhim, the new HDPE grade has successfully completed customer homologation in the beverage packaging segment and is ready for industrial-scale production.
SIBUR noted that domestically produced HD21550 CC allows converters to use locally sourced raw materials on existing manufacturing equipment, reducing dependence on imported alternatives and lowering logistics costs. The company believes the material will provide beverage packaging manufacturers with greater supply-chain resilience while expanding options for high-performance closure materials.
The launch further strengthens SIBUR’s portfolio of polymers for food and beverage packaging and reflects the industry’s growing focus on advanced materials that support lightweight packaging, manufacturing efficiency, product safety, and sustainability in beverage closures.
