i used to stuff/squeeze all my wires into one packed ziploc bag (laptop, usbC, microUSB, travel adapter, extension cord, camera charger...) in my backpack
but apparently it shows up as a black mass on the scanner, so they have to pull my bag, take out the bag of wires and rescan backpack+ziploc separately
now, i put it into two ziploc bags (and not extremely stuffed), no sisues afterwards
