The present invention relates to a head for wrapping loads, particularly for palletized loads, including at least one support framework for at least one reel of extensible material, the support framework including at least one pair of plates connected to each other through a longitudinal plate extending along a longitudinal axis (x-x) of the framework, the reel being supportable by the support framework parallel to the axis (x-x) and the extensible material, in use, can be unwound from the at least one reel along a delivery plane (P), at least means for the return of the extensible materials supported by the at least one support framework along the longitudinal axis (x-x). The wrapping head includes at least one group for folding the extensible material, downstream of the return means, the folding group being predisposed, in use, to engage and fold at least one peripheral portion (p) of such extensible material on itself, hence obtaining a double layer band (F) of such extensible material.
