Word of caution: relabeling boxes may raise some eyebrows depending on your end user.
We had an unrelated problem with a pallet that had been previously relabeled.
It played a small role in convincing us to discard it.
It may be worth the brand integrity to discard (and hopefully recycle) the boxes.
Thats why you'll never find a box of Cheerios with a revision sticker on it. The unaware consumer may get spooked.
Just something to think about :) Good luck!
