The bag has to match how the load compresses, how the package edges present to the bag, and how the force redistributes once transport begins.<\/p>\n<h2>Pressure retention decides whether stabilization lasts<\/h2>\n<p>A bag that loses meaningful pressure before arrival turns controlled transport into progressive load shift. That is why route time, seal behavior, and valve integrity matter as much as bag size.<\/p>\n<h2>Operator fill consistency is part of the system<\/h2>\n<p>Even a good dunnage bag performs poorly when inflation equipment and operator steps are inconsistent.
