18mm Child-Resistant Matte Black Cap (with PS Liner)

The 18mm child-resistant matte black cap is engineered as a secure and dependable closure option for cannabis and hemp packaging. Designed to fit compatible glass tubes, this cap provides enhanced product safety, freshness, and compliance.

Manufactured from durable polypropylene, the cap features a child-resistant push-and-turn mechanism, making it difficult for children to open while remaining convenient for adults. Its matte black finish offers a clean, premium look suitable for retail-ready products.

Each cap comes pre-inserted with a PS (polystyrene) liner to ensure a tight and reliable seal. Once the cap is closed, the liner is designed to adhere firmly to the rim of the tube within two minutes, creating an effective barrier that protects the product from air, moisture, and contamination. This airtight seal helps preserve aroma, flavor, freshness, and potency throughout storage and transport.

The 18mm child-resistant matte black cap is a practical, compliant, and high-quality solution for cannabis and hemp brands looking to maintain product integrity and enhance consumer safety.
