Introducing the Boveda Closure

Continuing its rich history of raising the bar for cannabis packaging, Boveda is proud to present the revolutionary Boveda Closure, an integrated cap that will boost efficiency, improve operations, and most importantly, protect flower from terpene evaporation and degradation.

Precise 2-Way Humidity Control Preserves Cannabis Quality and Consistency

The fully integrated Boveda Closure provides a convenient one-piece cannabis packaging solution to build quality and efficiency into tedious packaging activities. Now available in a conveniently threaded jar cap, the closure features 4 grams of Boveda’s saltwater cannabis preservation formula securely embedded in the lid.

The Boveda Closure deploys the same advanced technology as the 62% Relative Humidity (RH) Original Terpene Shield™ packets, but in an integrated cap for a range of plastic and glass jars. An all-natural, saturated salt solution ensures cannabis flower is optimally stored between 55-65% Relative Humidity (RH). Maintaining this stable environment protects against trichome damage, terpene loss, overdrying and mold—factors that affect your brand’s reputation and bottom line.


The Boveda Closure is compatible with a wide variety of plastic and glass jars that have the same matching neck specification. The diameter (finish) is 53mm, and is made of opaque, BPA-free, recyclable polypropylene (#5).

I’d Like to Hear More About the Boveda Closure


Who can purchase the Boveda Closure?

It does not have a humidity pack inside, but our patented 2-way humidity control solution is threaded into the cap. This allows for seamless, no-hassle cannabis packaging.

Does the Boveda Closure preserve terpenes?

Using our patented saltwater 2-way humidity control solution, the Boveda closure does preserve terpenes. This will ensure that your cannabis tastes, feels, and smokes perfectly when it gets into consumers hands.

Does the Boveda Closure keep cannabis at 58% RH or 62% RH?

The Boveda closure achieves a happy medium and preserves your cannabis between 55-65% RH. Maintaining this stable environment protects against trichome damage, terpene loss, overdrying and mold; factors that affect your brand’s reputation and bottom line.

Is the Boveda Closure easily customizable for cannabis packaging?

The Boveda Closure is purposefully sold in two solid, plain colors: black and white. These 2 colors comply with cannabis packaging regulations of most states, and are easily customizable.

How can you brand the Boveda Closure?

The flat-topped exteriors are non-branded, so a cannabis company can affix its own logo stickers post-purchase. Available in either black or white, the closure provides a neutral backdrop to a cannabis brand’s identity.

Is the Boveda Closure child-proof cannabis packaging?

Yes, the Boveda closure is child-proof. This child-proof cannabis package design complies with the cannabis packaging regulations of most states.

What sizes of the Boveda Closure are currently available for purchase?

The Boveda Closure is currently available for purchase in the following sizes: 

  • 1 Gram of Cannabis 
  • 3.5 Grams of Cannabis 
  • 7 Grams of Cannabis
Are the jar and the cap sold together or separately?

It’s your choice. You can buy the closure separate from the jar or the jar and closure together as a set.

Does medical marijuana have to come packaged in a child-proof container?

Typically, all cannabis must be packaged in a child-proof container. However, this information does vary from state to state.

Can you package cannabis with silica gel beads?

You can if your cannabis is excessively moist; however, a silica packet is merely a drying agent. It cannot prevent cannabis from overly drying out.

To guarantee cannabis stays between 55% and 65% RH—the safe zone for flower—use 2-way humidity control technology, which is directly embedded into the cap.
