This 28mm 28-400 White PP Plastic Cap offers a clean, professional look paired with reliable sealing performance for a wide range of products. Made from durable polypropylene (PP), the cap features a smooth top for a sleek finish and ribbed sides for improved grip during application and removal.
Inside, the cap is equipped with an F217 foam liner, a three-layer structure known for excellent chemical resistance, moisture barrier protection, and leak-prevention. The F217 liner is ideal for liquids, powders, and semi-solid products, helping maintain freshness and product integrity during filling, shipping, and storage.
This versatile closure is commonly used for personal care items, household cleaners, industrial chemicals, automotive fluids, food products (depending on regulatory requirements), essential oils, and specialty formulations. The 28-400 neck finish offers compatibility with a wide range of HDPE, LDPE, PET, and PVC bottles.
