PROCEDE ET MACHINE DE FABRICATION D'UNE POCHETTE D'EMBALLAGE ET POCHETTE OBTENUE PAR CE PROCEDE

摘要

Between folds (26a, 26b), a thermally-conducting body (44) is interposed. With respect to polypropylene, this is anti-adherent. Each weld (12) is made transversely with respect to a folded web (26) between the sheets (22, 24) and its direction of deposition. An independent claim is included for a corresponding machine to make the packaging.
