An apparatus for wrapping groups of products with plastic film comprises: a platform that rotates about a vertical axis and supports a group of products which, as the platform rotates, are wrapped with the film to form a package; a reel, from which the film is unwound, which rotates about a vertical axis and which can move up and down in such a way as to wrap the group in height as the platform rotates; a unit for gripping and tearing the film mounted outside the profile of the platform and designed to intercept and grip at least one portion of the film located between the group and the reel (4) once the group has been wrapped, in such a way that, acting in conjunction with a partial rotation of the platform, it tears the film at that portion to form an end or trailing free edge of film torn off by the gripping and tearing unit. The apparatus further comprises means for sealing the trailing free edge, mounted close to the platform and synchronised with the gripping and tearing unit to stably affix the trailing free edge to the wrapped product group.
