Not sure I agree with this philosophy. If the box is crushed on a corner or an end, I'd rather have air take the impact than the frame.
In the corners and elsewhere, I insert Poor Man's Bubble Wrap. A plastic grocery bag, partially filled with crushed up balls of newspaper, and then tied at the top of the bag. You can even use two bags, if you wish.
Now you have a pocket of air, complete with padding, both helping to cushion the impact. And then, after impact, the crushed newspaper actually tries to return to its shape, drawing air back into the plastic bag.
I invented this stuff myself.
