EzyDrop GL18

The GL18 plastic cap is a compact, high-performance 18mm closure, trusted across the health, wellness, and pharmaceutical sectors. Engineered for bottles with a GL18 neck finish, this closure provides a secure, threaded seal ideal for liquid medications, supplements, tinctures, and cosmetic serums — wherever product integrity and dosing precision are critical.

Manufactured from durable, injection-moulded polypropylene (PP) or polyethene (PE), GL18 caps are compatible with a range of liners, including pressure-sensitive, foam, and induction seals. These help maintain shelf stability, prevent leakage, and preserve the efficacy of sensitive formulations. Many variants support inserts such as droppers, reducers, or syringe adapters, enabling safe and accurate dosing for both professional and at-home use.

Ribbed or knurled options offer improved grip for users of all abilities, especially in clinical or homecare settings. With clean lines and a minimal footprint, GL18 caps are easy to handle, tamper-evident when required, and available in custom colours for brand alignment or product differentiation.

At Caps & Closures, we supply a comprehensive range of GL18-compatible plastic caps specifically designed for therapeutic, naturopathic, and wellness applications. Our closures support safe dispensing and regulatory compliance — empowering healthier outcomes with every dose.
