Finite goods are continuously packed between two non-wovens by means of hydrodynamic needling and are fully sealed. When used, said wovens should no t nap and should not become linked to the goods during packing. When packed, t he volume of the goods should, wherever possible, remain unchanged. In order to achieve said aims, the covering non-wovens are prefixed by means of hydrodynamic needling. Particularly good results are achieved if perforated non-wovens are used to cover the finite products, the number of said perforations being approximately 5-20 perforations per inch, and when said n on- wovens are joined to each other by means of water needling.
