Are biodegradable paper stickers vegan?

Yes.
The biodegradable paper material is made of sugarcane, hemp & a little linen. The material data sheet contains everything you need to know about this material.
We then print onto this material using low-energy, UV-cured inks, saving energy in production and removing the need for harsh solvents.
The ink also has a GREENGUARD Gold certification and is not made using animal products.
