It’s Bamboo Fiber
Biodegradable
Compostable plastic (PLA) and other materials (such as sugar cane straws) need to be heated up to 140°F to start breaking down. Bamboo fiber on the other hand will degrade on its own over a period of time through the action of naturally occurring microorganisms (such as bacteria and fungi). It’s 100% non-toxic. And 100% Earth Friendly.
Effective
Bamboo fiber performs better in our drinks than any other material we tested. It holds-up against all temperatures for an extended amount of time, and they don't melt/swell/break like other alternatives do.
Sustainable
Moving away from materials that use fossil fuels, bamboo is one of the most renewable resources on the planet - even beating other plastic alternatives like paper.
