The present invention relates to a ready-made film of an edible or inedible material for wrapping food products, wherein the film is characterized in that it is curved onto itself along a longitudinal axis to form a cylinder in which the lateral edges of the film are overlapping to a certain extent, shirred or wrinkled in the manner of an accordion to form folds perpendicular to the axis of said cylinder. The invention also relates to a process for preparing the above-described ready-made film for wrapping food products, wherein the preparation process is characterized in that it involves: a) forming a tube from the film, overlapping its edges to a certain extent; b) placing an internal support tube made of a stiff material; c) shirring the film cylinder only transversally or also longitudinally; d) placing a sheet for protecting the film; and e) shirring a net concentrically to the film. |
