I was looking at more sustainable packaging solutions and came across a company called Stora Enzo. They are a company that provides paperboard for packaging. It is a company that is committed to sustainability by producing lighter (therefore less material) packaging. Also they improve environmental performance where process management and controls are taken into consideration (dry debarking, process water recycling, effective emissions monitoring, safety and recycling systems, and cooling towers for biological waste water treatment). They also use steam for power. There wood fibres are managed from controlled forests. The packaging is fully recyclable. I feel like this would probably be better to use for a traditional box packing. This would be more practical and probably sell better to a wider target audience instead of expensive containers which could be reused but not practical to buy and reuse often ending up with tons of containers.

The particular paperboard used for packaging would be tambrite. It states on the website "Tambrite is a quality option for applications requiring high bulk, purity, solid structure and excellent printability. We worked in close cooperation with OTG and its printers and jointly decided that Tambrite is exactly the right solution, since the famous tea brands need to make a visually superb statement," says Peter Pöpping, Sales Manager at Stora Enso Deutschland.
The website also mentions how tea popularity is supposed to grow in the near future with a health-concious population. Below is an example of tea packaging, and cups (which could be an option as a container and reusable as a disposable recyclable cup) which use tambrite by Stora Enzo.
