Title
(EN) METHOD FOR SEALING THE MOUTH OF A FLEXIBLE SACHET OR POUCH
(FR) PROCEDE PERMETTANT DE FERMER HERMETIQUEMENT L'EMBOUCHURE D'UN SAC OU SACHET SOUPLE
Abstract
(EN) The invention relates to a method for sealing the mouth of a polymeric sachet or pouch (1), the method comprising the steps of: (i) forming the sachet or pouch with an open ended mouth (17, 27); (ii) filling the sachet or pouch through the mouth; (iii) sealing the mouth across substantially its whole width by the application of heat to form a first seal (30); and (iv) sealing the mouth across substantially its whole width by the application of ultrasonic energy to form a second seal (40).
(FR) L'invention concerne un procédé permettant de fermer hermétiquement l'embouchure d'un sac ou sachet en matière polymère (1), ce procédé comprenant les étapes suivantes: (i) formation du sac ou sachet avec une embouchure ouverte (17, 27); (ii) remplissage du sac ou sachet par son embouchure; (iii) fermeture hermétique de l'embouchure sur toute sa largeur par application de chaleur afin de former un premier joint hermétique (30); et (iv) fermeture hermétique de l'embouchure sur toute sa largeur par application d'une énergie ultrasonore pour former un second joint hermétique (40).
