A sheet (2) is made by the method of the invention, in particular for use for the punching of lids for packages, in that a PE layer (5a) and an additional layer PP (5b) are applied to a sheet layer (4) of polyester (PET) by coextrusion to form the finished sheet laminate (2). This ensures that the sheet (2) is transparent throughout, just as it provides the possibility of controlled delamination by separation of the PE layer (5a) from the PP layer (5b), when the sheet (2) is pulled off a package (1 ).
