Zusammenfassung:	通过直接在聚酯薄膜上挤塑-层压树脂，不影响粘固涂层或不用臭氧处理所述挤塑-层压树脂的熔融薄膜而获得具有优异的夹层粘合性的层压薄膜。在聚酯薄膜上通过挤塑-层压含有不饱和羧酸和(甲基)丙烯酸酯的乙烯共聚物(可与少量密度为840至900kg/m#+[3]的乙烯/α-烯烃共聚物进一步混合)可获得所述层压薄膜，所述不饱和羧酸组分的量为1至12％(重量)，所述(甲基)丙烯酸酯组分的量为2至25％(重量)。 A laminated film exhibiting excellent interlayer adhesiveness obtained by extrusion-laminating a resin directly on a polyester film without effecting anchor-coating or without treating the molten film of the extrusion-laminated resin with ozone. The laminated film is obtained by extrusion-laminating, onto the polyester film, an ethylene copolymer containing an unsaturated carboxylic acid and a (meth)acrylic acid ester, which may be further blended with a small amount of an ethylene/alpha-olefin copolymer having a density of 840 to 900 kg/m , the amount of the unsaturated carboxylic acid component being from 1 to 12% by weight and the amount of the (meth)acrylic acid ester component being from 2 to 25% by weight.
