43mm 43-400 White PP Plastic Smooth Top Cap, Smooth Sides with F217 Liner

The 43mm 43-400 White PP Plastic Cap with a smooth top and smooth sides is designed for reliable sealing and a clean, polished appearance. Manufactured from durable polypropylene (PP), this cap features an F217 liner—a three-layer foam liner with a low-density polyethylene (LDPE) core between two layers of LDPE film. This construction offers excellent chemical resistance and a tight seal, making it ideal for packaging liquids, powders, and other sensitive contents.

This closure is compatible with containers featuring a 43-400 neck finish, commonly used in personal care, pharmaceutical, nutraceutical, food, and chemical industries. The smooth top and sides give it a sleek profile, perfect for products that require a professional shelf presence. The F217 liner helps prevent leaks, moisture ingress, and odor transmission, ensuring product integrity and consumer confidence.

Weighing approximately 3.18 grams, the cap is lightweight yet functional and features a 6-thread-per-inch pitch for secure closure torque (recommended 17–27 in-lbs). Please note this cap is sold separately and should be tested for compatibility with your specific bottle and product.
