Изобретение относится к слоистым пластмассовым пленкам, которые предпочтительно можно использовать для упаковочных целей, более конкретно - к способной к термосварке слоистой пленке, содержащей основной слой из полипропилена и углеводородной смолы с точкой размягчения ≥ 130°С, содержащий 0,05 - 0,5 мас.% амида эруковой кислоты в качестве смазки, и нанесенный на каждую сторону основного слоя покровный слой из олефинового полимера, содержащий средство от слипания и 0,05 - 5 мас.% амида эруковой кислоты, при этом между основным слоем и покровным слоем размещен промежуточный слой из полипропилена с изотактичностью > 94 %, причем соотношение толщины промежуточного слоя и толщины основного слоя составляет 0,01 - 0,1.The invention relates to laminated plastic films, which can preferably be used for packaging purposes, more specifically to a heat sealable laminate film containing a base layer of polypropylene and hydrocarbon resin with a softening point ≥ 130 ° C, containing 0.05-0.5 wt. % erucic acid amide as a lubricant, and an olefinic polymer coating layer applied to each side of the base layer, containing an anti-caking agent and 0.05-5% by weight erucic acid amide, between the base layer and the coating m is placed an intermediate layer of polypropylene with an isotacticity> 94%, wherein the ratio of the thickness of the intermediate layer and the thickness of the base layer is 0.01 - 0.1.
