I regularly vacuum pack clothing when I travel and things move enough to change creases even in my carry-on luggage. I'm skeptical that it won't be disturbed in regular shipping unless specific measures are taken.
I used to buy vacuum packed peanuts, there was practically zero chance that they would move around. I also remember that when vacuum packing beddings the result was hard like a brick.
