| description | A laminate, an article comprising the laminate and a method for preparing the laminate are provided. The present disclosure relates to a laminate, comprising a first substrate comprising a metalized polyethylene-based (PE based) film; a second substrate comprising a polyethylene terephthalate-based film or a polypropylene-based film; and, an adhesive layer adhering the first substrate to the second substrate, wherein the adhesive layer is derived from a two-component solvent-based polyurethane adhesive composition; wherein the concentration of fatty acids or fatty acid derivatives in the metalized PE-based film is less than 300ppm, based on the total weight of the metalized PE-based film, wherein the two-component solvent-based polyurethane adhesive composition comprises a polyester polyol component and a polyisocyanate component, wherein the polyester polyol component has about 40wt%-60 wt %of aromatic rings in the backbone, based on the total weight of the polyester polyol and a molecular weight (Mw) between 5,000 and 50,000; and wherein the weight ratio of the polyester polyol component to the polyisocyanate component is from 100: 5 to 100: 30.
L'invention porte sur un stratifié, un article comprenant le stratifié et un procédé de préparation du stratifié. La présente divulgation concerne un stratifié, comprenant un premier substrat comprenant un film à base de polyéthylène (à base de PE) métallisé; un second substrat comprenant un film à base de poly(téréphtalate d'éthylène) ou un film à base de polypropylène; et une couche adhésive faisant adhérer le premier substrat au second substrat, la couche adhésive étant dérivée d'une composition adhésive de polyuréthane à base de solvant à deux constituants; la concentration d'acides gras ou de dérivés d'acides gras dans le film à base de PE métallisé étant inférieure à 300 ppm, par rapport au poids total du film à base de PE métallisé, la composition adhésive de polyuréthane à base de solvant à deux constituants comprenant un constituant polyol de polyester et un constituant polyisocyanate, le constituant polyol de polyester ayant environ de 40 % en poids à 60 % en poids de cycles aromatiques dans le squelette, par rapport au poids total du polyol de polyester et un poids moléculaire (p.m.) compris entre 5 000 et 50 000; et le rapport en poids du constituant polyol de polyester au constituant polyisocyanate étant de 100 : 5 à 100 : 30. |
