Maybe I should also have said that that the one strip of 7 air pockets had 5 that were flat, where one of the pockets had a clear blowout on one end. Not sure if this suggests there was enough movement or pressure to pop this, or if it was originally packed with a strip of air pockets that were partially flat. Perhaps it was packed better originally and in transit some of the air pockets went flat and stuff started being able to shift around?
