Why should unused paper be rewrapped?

Once unwrapped, paper continues to exchange moisture with its environment. Uneven change through the load can increase the risk of static, wavy/tight edges and unstable feeding. Protect leftovers with the original wrap or suitable moisture barrier and retain the opening time, environment and stock/batch reference. Rewrapping is not a guarantee that affected paper returns to its original condition; seek printer guidance if problems are visible.
