    摘要： The invention relates to a polyethylene based sealant film comprising an optional outer layer (O), a core layer (C) and an inner layer (I), wherein the core layer (C) is made of a core layer composition comprising a component (AC), being a first, preferably bi- or multimodal, linear low density polyethylene, optionally comprising one or more distinct alpha-olefin comonomers, having a Mw in a range of from 190 kg/ mol to 400 kg/mol and a ratio Mw/Mn in a range of from 11 to 15, and a component (BC) being a second, preferably bi- or multimodal, linear low density polyethylene, optionally comprising one or more distinct alpha-olefin comonomers, having a Mw in a range of from 80 to 115 kg/mol and a ratio Mw/ Mn in a range of from 1 to 6; wherein component (AC) has a higher density than component (BC), and component (AC) has a lower MFR 2 than component (BC); and wherein said component (AC) is present in said core layer composition in an amount of greater than 50 wt.% based on the total weight of the core layer composition.
    The invention further relates to a laminate and an article comprising this film. The invention further relates to the use of the laminate and/or the film for packaging applications.

    摘要： The present invention relates to a multilayered film comprising a skin layer (SKL), a core layer (CL) and a sealing layer (SL); wherein the sealing layer (SL) comprises (a) 15 to 85 wt.-% based on the total weight of the sealing layer (SL) of a specific metallocene-catalysed multimodal polyethylene copolymer (MMCP) and (b) 15 to 85 wt.-% based on the total weight of the sealing layer (SL) of a specific plastomer wherein components (a) and (b) add up to 100 wt.-%. The present invention furthermore relates to the use of said multilayered film as packing material, preferably for food and/or medical products.

    摘要： A multilayer film comprising at least three layers, two outer layers and a core layer, wherein the core layer comprises:
    10 to 40 wt%, (such as 10 to 24.5 wt%) based on the total weight of the layer, of an ethylene plastomer with a density of 865 to 915 kg/m 3 ; and
    15 to 60 wt%, based on the total weight of the layer, of a heterophasic polypropylene copolymer;
    said outer layers independently comprising 50 wt% or more, based on the weight of the layer, of a unimodal or multimodal linear low density polyethylene having a density of 908 to 935 kg/m 3 ;
    wherein said multilayer film comprises less than 5 wt% of ethylene vinyl acetate.
