Abstract: 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 300 ppm, 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 40 wt %-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.
