Un sac selon l'invention comporte une poche intérieure Il en matière thermosoudable en forme de tube fermé par une soudure thermique à l'extrémité inférieure et une enveloppe formée de plusieurs couches 13 à 16 en matière non thermosoudable formant un tube extérieur fermé à l'extrémité inférieure C, la poche intérieure 11 étant fixée uniquement à l'extrémité supérieure à la couche la plus intérieure 13 en matière non thermosoudable, de façon que, après remplissage avec le produit, la poche intérieure puisse être fermée par une soudure thermique et être sectionnée pour ne plus être fixée à la couche 13, le bord supérieur des couches extérieures étant ensuite rabattu et collé pour obtenir un sac contenant le produit dans une poche fermée et complètement libre à l'intérieur de l'enveloppe extérieure. Un sac selon l'invention convient en particulier pour contenir des produits alimentaires, des farines, des céréales et autres en quantité de l'ordre de 10 à 25 kg, par exemple.
