The process by which secretory products are packaged into vesicles and then released from the cells is known as

Exocytosis.

Explanation:

It is Exocyctosis because Exocyctosis is a process where membrane bound secretory vessicles which can contain soluble proteins,membrane proteins, lipids are released from the cell into the extracellular environment.

The release is possible because the vessicles join to the plasma membrane of the cell.

These secretory vessicles are formed from trans Golgi network.
