50mm Child-Resistant Matte Black Cap (with Pressure-Sensitive Liner)

Our 50mm Child-Resistant Matte Black Cap is one of the top-selling closures for cannabis flower jars, delivering a secure, compliant, and airtight seal for premium bud packaging. Built with a smooth push-and-turn child-resistant mechanism, it meets state regulatory requirements while remaining easy and intuitive for adult customers to open.

Each cap includes a pressure-sensitive (PS) liner, designed to form a strong bond with the jar’s rim once tightened. Within minutes, the liner creates a reliable tamper-evident seal, helping maintain freshness, safety, and product integrity throughout storage and transport.

Key Benefits of the PS Liner:

Tamper-evident seal that enhances consumer confidence

Strong odor control, ideal for potent flower strains

Improved freshness retention, helping preserve aroma and terpene quality

Effective moisture barrier for long-lasting product stability

No-heat activation—the seal forms automatically when the cap is closed

The matte black finish provides a sleek, modern, and high-end appearance that pairs perfectly with branded flower jars, custom labels, and retail-ready packaging.

When paired with compatible 50mm glass flower jars, this child-resistant cap delivers a complete, compliant, and polished packaging solution—ideal for eighths, quarters, and specialty small-batch flower.

A dependable, best-selling CR cap designed for premium cannabis flower.
