Someone is planning to bring fragile items (eg. glass bottle, steel bar, lamp, or electronics without Lithium battery) in a flight checked luggage.
That person tries to protect those fragile items with biodegradable foam peanuts put them together inside the suitcase.
Which one is better: to spread those foams within the suitcase or to contain the foams into several transparent plastic bags before putting it into the suitcase?
This question emerge to overcome some cases when the airport security officers want to open the suitcase and do checking.
