Plastic Caps & Closures: Precision Sealing Solutions for Every Industry

Plastic caps and closures are essential components in modern packaging, providing secure sealing, product protection, and user convenience across a wide range of containers and applications. Whether you’re packaging liquids, powders, granules, or viscous materials, choosing the right cap or closure ensures product safety, tamper resistance, and brand integrity.

What Are Plastic Caps & Closures?

These are molded components made from high-grade polymers such as Polypropylene (PP), HDPE, or LDPE. Designed to fit and seal containers like bottles, jerrycans, jars, and drums—either by threading, snapping, or specialized sealing—they play a critical role in maintaining product integrity.
