A method and a line for the high-speed packaging of filter bags () containing an infusion product comprises at least three successive operating steps whereby: the filter bags () are wrapped in a continuous protective tubular envelope () by sealing a continuous V-shaped folded strip () along a longitudinal sealing line () and transversal sealing lines (); the tubular envelope () is cut into lengths; and the filter bags (), individually wrapped in respective envelopes (), are placed in cartons. In the method and line () according to the invention, the transversal seal () is made in two successive steps as the continuous folded strip () moves through two separate consecutive sealing stations (), the first station () making a part of the transversal seal () and the second station () completing the same transversal seal ().
