Packaging method

The invention relates to a method for manufacturing a complex automotive glazing comprising a glass pane, an elastomeric seal and a metal insert overmolded with the elastomeric seal, the method comprising:-inserting an edge of the glass pane and the metal insert into a packaging mould, the encapsulation mold forms a sealed chamber surrounding the edge of the glass sheet,-filling the sealed chamber comprising the edge of the glass sheet and the metal insert by injecting an encapsulation composition comprising a polypropylene (PP)/thermoplastic elastomer (TPE) compound in a molten state,-cooling the encapsulation composition to form an elastomeric seal, the invention relates to a method for producing an elastomeric seal in which a metal insert is integrated,-demoulding the elastomeric seal in which the metal insert is integrated, characterized in that the PP/TPE compound comprises 30 to 80 wt.%, preferably 40 to 75 wt.%, in particular 45 to 70 wt.%, of polypropylene (PP), and the metal insert is covered with a
