Well, we use this too, and this week we realised that we'd upset some customers by using it until they learned what this stuff is made from, and how cool it is.
This is called bio-fill and it's made from 100% natural starch. We use it in your Happy, Woohoo and HESO parcels to keep your goodies secure while they get whisked around Australia (and the world). The really nifty thing is that it's biodegradable and compostable. You could chuck it on the garden, or even put it in your bathtub and wet it. It will magically disappear!
BUT... there are plastic alternatives that look a LOT like this good stuff. The way to tell the difference is to wet one and if it starts to break down right away then it's the goods.
So sometimes you might find us alternating between biofill and shredded paper to keep your order safe, and if you DO see this please don't worry. We have our beautiful planet in the forefront of our minds ALL THE TIME and would never use unnecessary plastic to pack your order.
