Abstract: The invention is a packaging machine using heat sealable film, of the type suitable for packaging the product (P) with a heat sealable film or net (S), through the use of heat sealing rollers that make the longitudinal edge of the wrap, of cut-and-sew blades that make the two transverse edges of said wrap and of a forming tunnel that shapes said film unwound from a reel. This machine is characterized in that the above-mentioned devices and their operating accessories are all applied to and supported by a single structure, in such a way as to form a working unit in a single piece which is connected with the pin to a support, integral with a fixed base and capable of rotating angularly on a vertical plane.
