Box boards offered by Conservation Resources lead the world in conservation technology. We were the first to put an alkaline reserve throughout our grey/white boxboards. Shortly thereafter, we introduced the first lignin-free papers and boards, known industry-wide as “Lig-Free” boards. This board is acid-free, lignin- free, and sulfur free and passes the PAT. It is tan on both sides. In most cases the largest of these sheets require truck shipping, though we now offer smaller sizes which are cut so they can generally ship UPS or FedEx. Sheets are sold individually allowing users to order as few or as many as they need. Minimum order of 10 sheets of boxboard.
