Vacuum Clothes

I think putting my clothes, jackets and other stuffs in a vacuum packed plastic so I could make more of them in one bag when I travel. Is there a risk that the air pressure in the aircraft cargo will pack vacuum to suck the air and fills all in high altitude? Thank you for your opinion. Thank you.

Since the cargo holds of commercial aircraft are pressurized, the vacuum bag will experience very little change in pressure. At most, the bag to expand slightly during the flight, but he will return to normal as the plane descends.

They can "breathe" a bit during the flight, the external pressure decreases.
