  • MAH maleic anhydride
  • the pour spout 34 made of the same material as the layer 2, is brought face-to-face into contact with the surface 26 and then high-frequency welding is employed to bond the flange 36 of the spout 34 directly to the layer 2. Since none of the layers 4 to 24 and 24' to 16' is susceptible to sealing by high-frequency welding, they are unaffected by the welding process. This is particularly important at the location where the surface 28 is brought face-to-face into contact with itself during welding of the fitment flange 36 to the layer
  • the pouch may be filled with a liquid product to be used in the medical field, such as functional foods and nutraceuticals, in which case the layer 2 is mainly or wholly of EVA, because EVA does not produce dioxins under high- frequency welding.

Abstract

Dans un système de conditionnement, un élément unitaire (34) constitué sensiblement entièrement de thermoplastique capable de convertir un rayonnement électromagnétique haute fréquence en chaleur est comprimé contre un contenant (32) comportant des première et deuxième parois opposées dont au moins une est facilement souple et mise en contact avec l'autre, ladite première paroi comprenant une surface externe (26) également réalisée en thermoplastique capable de convertir l'énergie électromagnétique haute fréquence en chaleur et comprenant des surfaces internes opposées respectives (28) en thermoplastique qui, comparativement aux thermoplastiques de l'élément unitaire (34) et de la surface externe (26), possède une aptitude relativement faible à convertir le rayonnement électromagnétique haute fréquence en chaleur, et par conséquent à comprimer les surfaces internes (28) ensemble; l'élément unitaire (34) et les surfaces externes (26) étant soudés ensemble par soudage haute fréquence sans pour autant souder ensemble les surfaces internes (28).
