A method for producing a shaped sheet of wrapping, comprising a hollow portion and a perimetral edge that extends along a pre-set profile, said method comprising the steps of: - laying a sheet of wrapping on a treatment surface having a forming cavity; and - forming said sheet of wrapping within said forming cavity so as to reproduce the shape of said hollow portion thereon, wherein said forming step includes inserting said sheet of wrapping into said forming cavity, without subjecting it to deformation by stretching at least for a phase of said action of insertion, said formed sheet having a plurality of folds consisting of two or more layers set on top of and in contact with one another of said sheet of wrapping; - cutting said formed sheet of wrapping along said pre-set profile for producing said perimetral edge and obtaining said shaped sheet of wrapping; said method being characterised in that said cutting step comprises the use of a laser source designed to emit a laser beam, and includes applying said laser beam on said formed sheet and orienting said laser beam so as to carry out a plurality of passes of said laser beam along said pre-set profile, wherein said plurality of passes comprises: - a first pass of said laser beam that follows a first path; and - at least one further pass of said laser beam that follows a further path (P2, P3,..., Pn) that is shifted from said first path, in a direction away from said pre-set profile, by a given distance (d1, d2) such that the laser beam that follows said further path (P2, P3,..., Pn) can operate on an underlying layer of the formed sheet that still connects said shaped sheet to a residual portion of said sheet of wrapping and that emerges on the side where the laser source is located as a result of said first pass of said laser beam. - laying a sheet of wrapping on a treatment surface having a forming cavity; and - forming said sheet of wrapping within said forming cavity so as to reproduce the shape of said hollow portion thereon, wherein said forming step includes inserting said sheet of wrapping into said forming cavity, without subjecting it to deformation by stretching at least for a phase of said action of insertion, said formed sheet having a plurality of folds consisting of two or more layers set on top of and in contact with one another of said sheet of wrapping; - cutting said formed sheet of wrapping along said pre-set profile for producing said perimetral edge and obtaining said shaped sheet of wrapping; said method being characterised in that said cutting step comprises the use of a laser source designed to emit a laser beam, and includes applying said laser beam on said formed sheet and orienting said laser beam so as to carry out a plurality of passes of said laser beam along said pre-set profile, wherein said plurality of passes comprises: - a first pass of said laser beam that follows a first path; and - at least one further pass of said laser beam that follows a further path (P2, P3,..., Pn) that is shifted from said first path, in a direction away from said pre-set profile, by a given distance (d1, d2) such that the laser beam that follows said further path (P2, P3,..., Pn) can operate on an underlying layer of the formed sheet that still connects said shaped sheet to a residual portion of said sheet of wrapping and that emerges on the side where the laser source is located as a result of said first pass of said laser beam.
