Borouge, a joint venture between Abu Dhabi National Oil Company (ADNOC) and Borealis Chemical, leverages its patented Borstar technology and over 50 years of expertise in polyolefins to support key industries such as infrastructure, automotive, and advanced packaging. The company's BNT nucleation technology is widely used in the production of films, fibers, and thermoformed products, as well as in injection and blow molding applications. These technologies are driving innovation in plastic bottle packaging, caps, closures, thin-walled packaging, and household goods.
In the beverage industry, there has been a growing focus on innovative, value-added plastic solutions that reduce unnecessary packaging, lower carbon emissions, and offer more cost-effective options. Packaging plays a crucial role in protecting food and minimizing waste, and even with reduced material usage, these solutions must maintain high performance to ensure product quality, safety, and functionality. As a leader in this space, Borouge has developed sensory HDPE beverage covers and finishing shrink film solutions tailored for modern beverage packaging needs.
One of the key developments is the shift toward lightweight sealing caps. The standard short-necked PCO1881 cap has gained popularity globally, prompting Borouge to introduce two advanced materials—BorPure MB5568 and MB5569—from its BorPure™ high-density polyethylene (HDPE) family. These materials are ideal for carbonated drinks, teas, and juices, offering excellent sensory properties. While MB5568 is free from slip aids, MB5569 includes them for optimal torque performance.
Thanks to enhanced design capabilities enabled by Borstar polymers, BorPure materials have already shown strong environmental stress cracking resistance. The new MB5568/9 variants offer a 50% improvement in this area, along with a 10% increase in hardness. Additionally, their flowability and processability match those of traditional unimodal MFR2 HDPE resins, allowing for further weight reduction without compromising appearance or performance.
Another key advantage is that BorPure MB5568/9 materials do not impart any odor to bottles, ensuring consistent quality across batches. This is especially important for brand owners who aim to reduce preform weight from the outset, as plastic resins make up the majority of a bottle’s cost. In 2006, the International Beverage Technology Association introduced the PCO1881 standard, which allows for a 20-30% weight reduction in sealing caps compared to the previous PCO1810 model. This trend has also led to the transition from two-piece PP seals to single-piece HDPE alternatives, offering both material and cost savings while maintaining seal integrity and barrier properties.
The unique Borstar technology behind BorPure MB5568/9 significantly enhances environmental stress cracking resistance and hardness, making it an ideal choice for lightweight caps without sacrificing performance. This development supports the customization of mechanical and processing properties of PE materials, boosting product competitiveness and promoting sustainable growth in the beverage sector.
In addition to caps, Borouge also provides efficient bundled packaging shrink film solutions for the beverage industry, further enhancing efficiency and sustainability in packaging operations.
