Abstract: A sealing jaw (1) for producing sealed packages of a food product from a tube (3) of packaging material fed along a path (A), the jaw having a first work surface (28) which interacts with a second work surface (29) on a counter-jaw (2) to grip the packaging material and form a sealing strip (6) crosswise to the path (A); one (1) of the jaw and counter-jaw (1, 2) defining an anvil (9), and the other (2) of the jaw and counter-jaw (1, 2) defining heating means (8) which interact with the anvil (9) to form the strip (6). The first surface (28) has at least two projections (35, 36; 36, 36; 36, 37) elongated along respective first axes (X), and which, when forming the strip (6), compress respective areas of the packaging material against the second surface (29); and at least one cavity (40) which extends along one of the first axes (X), is interposed between the projections (35, 36; 36, 36; 36, 37) along a second axis (Y) crosswise to the first axis (X), and is located laterally with respect to a central plane (P) of the first work surface (28).
