(EN) A METHOD AND A PACKAGING APPARATUS FOR FORMING SEALED PACKAGES
(FR) PROCÉDÉ ET APPAREIL D'EMBALLAGE POUR FORMER DES EMBALLAGES SCELLÉS
Abstract
(EN)
There is described a method for forming sealed packages (2) filled with a pourable product comprising at least the steps of forming a tube (3) from a web (4) of packaging material, filling the pourable product into the tube (3) for forming a product column (8) within the tube (3) and directing, during the step of forming and the step of filling, a sterile gas into the product column (8) for forming and/or maintaining a gas cushion (10) within the product column (8).
(FR)
L'invention concerne un procédé de formation d'emballages scellés (2) remplis d'un produit versable comprenant au moins les étapes consistant à former un tube (3) à partir d'une bande (4) de matériau d'emballage, à remplir le tube (3) de produit versable pour former une colonne de produit (8) à l'intérieur du tube (3) et à diriger, pendant l'étape de formation et l'étape de remplissage, un gaz stérile dans la colonne de produit (8) pour former et/ou maintenir un coussin de gaz (10) à l'intérieur de la colonne de produit (8).
