The present invention discloses a packaging apparatus and a packaging device. The packaging apparatus comprises a mask plate and a control circuit that is electrically connected to the mask plate and is used to control the mask plate such that the mask plate electrostatically adsorbs a first substrate or release the first substrate. In the technical solutions of the present invention, the mask plate is controlled by the control circuit such that the mask plate electrostatically adsorbs or releases the first substrate without the need to use the alignment mechanism of mechanical fixing type to fix the first substrate. By completely adsorbing the first substrate by the mask plate in a way of electrostatic adsorption, the deformation of the first substrate and the generation of bubbles between the first substrate and the second substrate are avoided, the alignment precision is improved, and the slip-off of the first substrate from the mask plate during the process of pressing is avoided.
