Is there a good way to remove duct tape from a box?

[electricsjay]

So its my first time selling on eBay and shipping an item and i just learned that you can't use duct tape after covering the box with duct tape and after paying for the shipping label, so i wanted to know if there was anyway to remove the duct tape without damaging the box or leaving sticky residue, is there any way ? I thought of emptying the box and then put the box in the freezer to make the duct tape unstuck or just easier to remove from the box because i learned that duct tape doesn't really stick in the cold and am not too sure of my idea is a good one.

I'd really like to find a way to do this without having to void the label, also the box used is a shoe box so i need to re-use this box to make sure its the same size as when i created the label.

Thank you in advance for tacking your time to help me.

EDIT: my post office accept duct taped package as long as its well sealed/taped

I tried to send items in a liquor box once because they are so sturdy but that is not allowed.  So I just covered the whole box with brown paper like from old paper bags or the underside of wrapping paper.  If you don't have a new box & have to reuse this box try putting brown paper all around the box to cover the duct tape & then put on the shipping label. You should have no problem.
