Abstract:
An overwrap envelope (7) containing a filter bag (1) for infusion products comprises a sheet (2) of overwrapping material folded into a U shape along its transversal axis (X) around the filter bag (1). The overwrap envelope (7) has two longitudinal sides (3, 4) and one transversal side (5) sealed by at least two sealing lines (6) which are uninterrupted along the longitudinal sides (3, 4) and along the transversal side (5). Each sealing line (6) is defined by two longitudinal stretches and one transversal stretch which are joined to obtain an uninterrupted shape and which form an uninterrupted perimeter seal.
