An apparatus for making packages (1) comprising groups (2) of products wrapped with stretch film comprises the following: a transporting surface (3) for conveying groups (2) of products presenting a front face (FD) in a defined feed direction (A); a first pair of film feed stations (4, 5) located on opposite sides of the transporting surface (3); a first selection carriage (6) comprising at least two units (7, 8) for forming a respective tubular length (9, 10) of film fed by the respective stations (4, 5), and means (11) for driving the first carriage (6) to and fro in a direction transversal to the feed direction (A) in such manner as to cyclically perform the following operations: forming the tubular length of film (9) on a first unit (4) outside the transporting surface (3), and at the same time positioning the other unit (5) with the respective tubular length of film (10) on it in a stretched configuration at the transporting surface (3) to form a part of the latter so as to enable feeding of the group (2) of products into the tubular length of film (10) and releasing of the tubular length of film (10) over the group (2) of products to form a wrapped package (1).
