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

Our 50mm Child-Resistant Matte White Cap is one of the top-selling closures for cannabis flower jars, offering a secure, compliant, and airtight seal ideal for premium bud packaging. Featuring a smooth push-and-turn child-resistant mechanism, this cap meets state regulatory standards while remaining simple and intuitive for adult consumers to open.

Each cap is equipped with a pressure-sensitive (PS) liner, engineered to bond firmly to the jar’s rim once tightened. Within minutes, this creates a dependable tamper-evident seal, ensuring freshness, safety, and product protection from packaging to final sale.

Key Benefits of the PS Liner:

Tamper-evident seal for added consumer confidence

Strong odor control, ideal for potent flower strains

Enhanced freshness retention, preserving aroma and terpene quality

Effective moisture barrier to maintain long-term product stability

No-heat activation—the seal forms automatically upon closing

Finished in a clean matte white coating, this cap provides a modern, premium appearance that pairs perfectly with branded flower jars, custom labeling, and retail-ready packaging.

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

A reliable, high-performance CR cap designed specifically for premium cannabis flower.
