PROCEDE DE FABRICATION D'UN EMBALLAGE PAR FORMAGE ET FIXATION D'UN FLAN EN MATIERE SEMI-RIGIDE

摘要

The invention relates to a method of producing a package by forming and fixing a semi-rigid blank. The inventive method consists in: cutting perforated lines (E1 to E5) into a substrate (PC) at pre-determined points; fixing a strip of heatweldable film to the substrate in the areas comprising said lines (E1 to E5) at least; cutting a blank from the support/film assembly, such that the cut for said lines (E1 to E5) enables parts of the film to project out; folding the blank and fixing at least two parts thereof by thermoforming at least one projecting part.
