A process for the realization of box-shaped packagings with thermoplastic film sheets foresees the use of at least one film sheet of thermoplastic material (12, 13), bound to a flap (14, 15) of a box (11), when the same is placed in a laid down configuration, and comprises the following steps; placing the box (11) in such a way as to be able to take said film sheets (12, 13) away, leaving the bottom of the box (11) accessible; inserting the products (21) in the box (11); wrapping the products (21) into said film sheets (12, 13); heating the content of the box (11) with means for providing a concentrated ventilation from the top; and, once the shrinking of the thermoplastic material has occurred, closing the box (11) at the open side.
