. Since the flux is in constant contact with the solder powder, it is continually acting on the oxides on the surfaces of the solder powder or spheres, and this action reduces the activity levels of the fluxes

don’t want to be liable for failures in the field due to old material. As for the cored wire solder, similar storage issues apply, but more to the point, the real concern is the changing activity of the flux in the core due to its corrosive or acidity properties working
