Main Features & Benefits of Borouge RJ768MO

  • Excellent Flowability and Processing Efficiency. With a high melt flow rate, Borouge RJ768MO enables easy mold filling, even in complex or thin-walled designs. This allows for shorter cycle times, reduced injection pressure, and improved productivity on high-speed injection molding lines.
  • Superior Transparency and Gloss. The optimized polymer structure and nucleation system deliver high clarity, low haze, and excellent surface gloss, ensuring visually appealing finished products with a premium appearance.
  • Balanced Mechanical Performance. PP RJ768MO provides a well-balanced combination of stiffness, strength, and impact resistance, ensuring reliable performance while maintaining lightweight and thin-wall designs.
  • Low Warpage and Dimensional Stability. Thanks to controlled crystallization behavior enabled by Borstar® BNT technology, the material exhibits low shrinkage and warpage, supporting consistent part dimensions and high molding accuracy.
  • Good Antistatic and Sensory Properties. The resin formulation helps reduce static charge build-up and offers low odor and taste neutrality, making it suitable for consumer-facing and food-related applications.

Typical Applications

  1. Thin-walled food packaging: This is one of its core application areas, suitable for producing thin-walled food containers, food lids, fresh-keeping boxes, and other products. Its high transparency allows consumers to clearly see the food inside, its high fluidity is ideal for mass injection molding production, and its odorless and food-grade certified characteristics ensure food safety.
  2. Household and daily necessities: RJ768MO can be used to manufacture thin-walled transparent household items, such as various storage boxes and small storage containers. The molded products have sufficient rigidity to withstand the weight of everyday items, and their impact resistance prevents damage from minor collisions.
  3. Media packaging: The material is suitable for the production of media containers such as CD cases and small electronic accessory packaging boxes. Its excellent molding precision meets the dimensional accuracy requirements of these products, and its high transparency facilitates the display of internal media or accessories.
  4. In-mold labeling products: Borouge RJ768MO is suitable for in-mold labeling processes, allowing for simultaneous labeling and molding during production, reducing subsequent processing steps. This is ideal for various packaging products that require decorative appearance, improving product aesthetics and production efficiency.
