摘要： The invention relates to a polyethylene sealant film comprising an 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, which is a recycled low density ethylene polymer in an amount of at least 50 wt. %, based on the total weight of the core layer composition, and a slip agent; and the inner layer I is made of an inner layer composition comprising a component AI, which is a linear low density ethylene polymer having a density of from 910 to 925 kg/m3 and an MFR2 of from 0.5 to 2.0 g/10 min. determined according to ISO 1133. The invention further relates to a laminated polyethylene film and article comprising this polyethylene sealant film. The invention further relates to the use of the laminated polyethylene film and/or the polyethylene sealant film for packaging of an article.
