There is disclosed a method and an apparatus for making a medium-filled packing of two superposed heat-sealable elongated webs of plastic film (3) which are thermally sealed in longitudinal and transverse directions of the film webs for forming packings (11), and where the formed packings are filled by medium and closed. The film webs (3) are passed between a pair of rollers (6) which are pressed against each other, retaining the film webs therebetween. Thermal sealing across part of the width of the film webs is performed so that unbroken longitudinal areas (9) without any thermal sealing appear in the longitudinal direction of the film webs (3). The medium is filled into the packing before closing it for the formation of the medium-filled packing.
L'invention concerne un procédé et un appareil de fabrication d'un emballage rempli d'un milieu. L'emballage est constitué de deux bandes de film plastique (3) allongées superposées, thermoscellables. Les bandes de film sont thermoscellées dans les sens longitudinal et perpendiculaire pour former des emballages (11). Les emballages ainsi formés sont remplis d'un milieu et fermés. Les bandes de film (3) passent entre deux rouleaux (6) pressés l'un contre l'autre qui les retiennent. Le thermoscellage est réalisé sur toute une partie de la largeur des bandes de film, de façon à laisser apparaître des zones longitudinales ininterrompues (9) non thermoscellées dans le sens longitudinal des bandes de film (3). L'emballage est ensuite rempli du milieu et fermé.
