I'm happy to say that HUGS Clay packaging is made from sugarcane. It took a good long while to find something ultra friendly and suitable for wrapping clay, but this white sustainably-sourced material seems to fit the bill. I order it from Kite Packaging Ltd. It comes in bag form - which I carefully cut to my desired shape. One of my main considerations when packing the clay is that it retains its moisture. Clay in its wet, malleable state is soft and easy to form - which is what people want. Thankfully sugarcane packaging has the ability to retain the clay's water content, whist at the same time looking after environment. It's a win win situation!
