A bale wrapper apparatus for applying stretch film wrapping to an agricultural hale (10) having an outer surface (10a) and a pair of opposed end faces (10b) and which comprises: a table for supporting the bale (10) with its longitudinal axis (11) extending substantially parallel to the ground, and for rotating the bale generally about this axis during a wrapping cycle； at least one holder arrangement (12) for supporting a film dispenser arrangement (15, 16) to apply stretch film wrapping (17, 18) to cover the outer surface and (10a) and the end faces (10b) of the bale (10), said holder arrangement comprising two holders (13, 14) each adapted to support a respective film dispenser (15, 16) and arranged to allow two lengths of film (17, 18) to be withdrawn from the dispensers (15, 16) and to be applied to the bale (10)； means for applying relative rotation between the table and the holder arrangement (12) about a second axis (19) extending substantially perpendicular to the longitudinal axis (11) of the bale (10) in order that successive windings of film can be applied to the hale； and means for adjusting the positions of the two holders (13, 14) relative to each other during the wrapping cycle between first and second wrapping positions to convert the apparatus from a first wrapping mode to a second and/or further wrapping mode(s): in which the wrapping cycle of the apparatus is programmed, or programmable, such that；a) initial coverage (22) of the bale (10) is carried out with the holders (13, 14) in the first wrapping position such that the two lengths of film (17, 18) are brought into at least partial overlapping engagement (21), prior to, or at the moment of application as at least partly laminated windings on the outer surface (10a) and the end faces (10b) of the bale (10) to form an initial coverage layer (22) on the bale and having a first wrapping profile； andb) the holders (13, 14) are thereafter adjustable to a second wrapping position in which the two
