Why is the higher the elevation, the more food bags inflate? From a physical point of view
The higher the altitude, the less the atmosphere, the smaller the pressure, and the pressure in the food package is a fixed value. The reason for the swelling of food packaging bags is that the pressure inside the food bags is greater than the external pressure!
The higher the altitude, the thinner the air outside, the lower the air pressure; and the air pressure inside the food bag is high, which causes the food bag to drum up. As the height gets higher, the air pressure outside may be lower, and food bags are likely to burst because of the pressure inside and outside
Because the food packaging bag is sealed, the air pressure inside is certain, with the elevation of the outside air pressure gradually decreased, which leads to gas bag outward extrusion pressure increased, so the higher the altitude, the food packaging bag inflated more.
