Description
The 89-400 CAP, a black polypropylene (PP) continuous thread closure, is engineered for superior sealing and product integrity in the supplement industry, particularly for powder-filled containers. Manufactured from high-grade virgin polypropylene, this cap offers excellent chemical resistance, ensuring it does not react with or leach into sensitive powdered ingredients. Its 89-400 neck finish is a standard in the industry, providing broad compatibility with various jar types. The smooth skirt and top design offer a clean, professional aesthetic, crucial for brand presentation. Equipped with an induction liner (universal type), this cap provides an airtight, tamper-evident seal, which is paramount for consumer safety and product freshness. The vented design further enhances its functionality, allowing for pressure equalization within the container, a critical feature for products that may off-gas or are sensitive to atmospheric pressure changes during shipping or storage, thus preserving product stability from manufacturing to end-user.
