摘要： A biaxially oriented polyethylene film structure comprises at least three layers, wherein three adjacent layers each comprise: i) from 50 to 99.5 weight percent of a first polyethylene which is an ethylene copolymer having a density of greater than 0.940 g/cm3; and ii) from 0.5 to 50 weight percent of a second polyethylene which is a high density polyethylene having a density of at least 0.950 g/cm3; wherein the high density polyethylene further comprises a nucleating agent or a mixture of nucleating agents. The biaxially oriented film has very good optical properties.

摘要： An uniaxially oriented polyethylene film, comprising multiple layers including an inner surface layer (I), an outer surface layer (O) and a core layer (C), wherein at least one of the inner surface layer (I) and the outer surface layer (O) is made of a composition comprising a multimodal linear low density ethylene (LLDPE) terpolymer component (PE1) with a density between 920 to 940 kg/m3, in an amount of from 30 to 100 wt.% of based on the total weight of the respective layer composition; wherein at least two of the multiple layers are made of a composition comprising a multimodal HDPE component (PE2) with a density of more than 950 kg/m3 up to 970 kg/m3. A laminate or an article comprising the polyethylene film as described herein, wherein the article is a packaging material. Use of the polyethylene film or the laminate as described herein for packaging of articles. A food package comprising the polyethylene film or the laminate as described herein.
