These boxes are uncoated and no chemicals are used to change their natural organic appearance, but the ''natural'' is more than skin deep.
This Natural Brown paperboard uses around 25-30% less fiber than other box materials. Compared to other virgin fiber products, that''s 25-30% fewer trees to produce the same amount of boxes. Against bleached paperboard, it is better for the environment because strong solvents are not used to bleach the pulp. Also, the fiber for these brown/brown boxes comes from SFI (Sustainable Forestry Initiative) lumber - lumber collected and reforested utilizing environmentally friendly practices.
