the load is complete, wrapped, and settled into position. Precise gap control is the first step toward predictable restraint.<\/p>\n<h2>Pressure retention tells you whether the restraint survives the route<\/h2>\n<p>Pressure retention deserves more attention than peak inflation. Teams should evaluate how the bag behaves after dwell, vibration, and temperature variation.<\/p>\n<h2>Container stability depends on the whole load system<\/h2>\n<p>Even a strong dunnage air bag cannot compensate for poor pallet condition, weak carton faces, or badly planned stacking.
