Abstract[English]
The present invention is primarily directed to a multilayer paper-based metallized packaging material (1) comprising, from its outer side to its inner side: - a paper layer (2) having a grammage comprised in the range of 40 to 120 g/m2, - a first pre-metallization dispersion coated layer (3) comprising a polymer having a low glass transition temperature (Tg), - a second pre-metallization dispersion coated layer (4) comprising a polymer having a high Tg, - a vacuum deposited metallization layer (5), and - a dispersion coated sealing layer (6).[French]
La présente invention concerne principalement un matériau d'emballage métallisé multicouche à base de papier (1) comprenant, de son côté externe à son côté interne : une couche de papier (2) dont le grammage est compris dans la plage de 40 à 120 g/m2 ; une première couche (3) revêtue d'une dispersion de prémétallisation contenant un polymère à faible température de transition vitreuse (Tg) ; une seconde couche (4) revêtue d'une dispersion de prémétallisation contenant un polymère à Tg élevée ; une couche de métallisation (5) déposée sous vide ; et une couche de scellement (6) revêtue d'une dispersion.
