Abstract

Des feuilles (11, 31) permettent la formation de sacs perméables à l'air destinés à l'emballage de produits ou d'enveloppes en papier, qui comprennent une feuille de départ en papier relatif à laquelle on applique une couche de matériau thermosoudable approprié dans des régions prédéterminées (14, 16,18, 34, 36, 38) de sa surface. Une partie de ces régions thermosoudables est ensuite superposée aux parties restantes des mêmes régions, ces parties superposées étant partiellement soumises à une pression adéquate et chauffées jusqu'à une température appropriée pour effectuer le soudage et former le sac ou l'enveloppe voulue. Les feuilles (11, 31) sont disposées de préférence en plusieurs séries continues de manière à former un tissu (12A, 12B, 32), si possible sous la forme d'un rouleau (10A, 10B, 30) de manière à permettre l'utilisation de machines d'emballage automatique de produits ou de formation d'enveloppes.
