38mm Child-Resistant Matte Black Cap (with Foil Liner)

Our 38mm Child-Resistant Matte Black Cap is designed for concentrate jars, delivering a secure, airtight, and compliant closure for high-quality extracts. Featuring a smooth push-and-turn child-resistant mechanism, this cap helps meet strict state packaging requirements while offering an easy, intuitive experience for adult consumers.

To ensure maximum freshness and product protection, each cap includes a premium foil liner. This advanced liner creates a powerful airtight barrier once the cap is tightened, helping preserve the integrity of concentrates such as live resin, rosin, wax, crumble, shatter, distillate, and terp-rich extracts.

Key advantages of the foil liner include:

Superior aroma and terpene retention

Exceptional oxygen and moisture barrier

Enhanced leak prevention for viscous or semi-fluid concentrates

Improved shelf-life and product stability

Reliable odor control during storage and transport

The matte black finish adds a sleek, premium look that pairs perfectly with custom labels, branded packaging, and display-ready jars.

When matched with compatible 38mm concentrate jars, this child-resistant cap provides a complete, dependable solution that protects your product’s freshness, potency, and presentation from production to point-of-sale.
