The invention provides a high-density packaging body, a lead wire framework, a packaging unit and a packaging method. A high-density packaging array comprises a plurality of packaging bodies, wherein each packaging body includes a packaging part and a plurality of pins protruding from the packaging part; every two adjacent pins of each packaging body are connected through a barrier strip; and the pins of each packaging body are mutually separated from the barrier strips of the adjacent packaging body. The high-density packaging body, the lead wire framework, the packaging unit and the packaging method have the advantages that as the pins of each packaging body are mutually separated from the barrier strips of the adjacent packaging body, thus reducing the space occupied by the pins, improving the packaging density; a high-density packaging array can be provided; the distance between the barrier strips and the packaging bodies can be increased; and during the plastic packaging process, barrier blocks of a die can be inserted between the barrier strips and the packaging bodies, thus avoiding generation of flash fundamentally.
