The first all-paper rigid box solution in cannabis packaging.

In 2020, California passed a law requiring that all cannabis products must be enclosed in child-resistant packaging. After surveying the industry, we analyzed samples and familiarized ourselves with testing procedures. The results were clear: too much plastic and too many overly complicated CR mechanisms. Our three design requirements also became clear. We were determined to create packaging using only recyclable materials, we wanted an elevated product presentation, and we needed to build a flexible CR system to accommodate diverse and specific needs for cannabis products.


Currently, most child-resistant mechanisms on the market are physically and cognitively difficult to operate. While inhibiting children is the goal, physically challenging packaging can affect broader accessibility. In response, we designed human-centered packaging featuring a mechanism that is sensitive and discrete without being physically taxing. After multiple prototypes with simple 2-part opening sequences, we landed on the final Zenlock system that balances graphics and mechanics to be intuitive for adults yet impenetrable to young hands.


Showcasing award-winning CR technology.

The Zenlock website introduces the sustainable CR system to potential cannabis brands, manufacturers, and distributors. It leads with white box samples because Zenlock is a product for any cannabis brand to utilize in their operation. It’s designed for full-coverage lithographic printing so that the mechanism can fit seamlessly into brand identity. The site also features Haptik-produced video content and photography demonstrating the Zenlock features.
