摘要： The present invention relates to a multilayer film comprising: • an inner layer system comprising a first surface and a second surface; • a first skin layer bound to the inner layer system at the first surface of the inner layer system; and • a second skin layer bound to the inner layer system at the second surface of the inner layer system; wherein • the inner layer system comprises a first ethylene-based polymer; and • at least one of the first or the second skin layer(s) is a sealing layer and comprises a second ethylene-based polymer having a peak melting temperature Tpm of at least 10° C. below the Tpm of the first ethylene-based polymer, Tpm being determined as peak melting temperature in accordance with ASTM D3418 (2008); wherein the multilayer film is a bi-directionally oriented film wherein the orientation is introduced in the solid state. Such film allows for the production of a sealed package having a sufficiently high sealing strength at reduced sealing temperatures, also referred to as the seal initiation temperature.

摘要： The present invention relates to a film comprising at least one sealing layer wherein at least one layer A of the sealing layer(s) comprises a polyethylene comprising moieties derived from ethylene and moieties derived from an α-olefin comprising 4 to 10 carbon atoms, the polyethylene having a density of ≥870 and ≤920 kg/m3 as determined in accordance with ASTM D792 (2013), wherein the polyethylene has: x a fraction of material that is eluted in analytical temperature rising elution fractionation (a-TREF) at a temperature ≤30.0° C. of ≥5.0 wt %, preferably ≥10.0 wt %, with regard to the total weight of the polyethylene; x a shear storage modulus G determined at a shear loss modulus G″=5000 Pa of >700 Pa, G′ and G″ being determined in accordance with ISO 6721-10 (2015) at 190° C.; x a melt mass-flow rate, determined at 190° C. under a load of 2.16 kg in accordance with ASTM D1238 (2013) of ≥2.60 and ≤4.90 g/10 min; and x a chemical composition distribution broadness (CCDB) of ≥15.0, preferably ≥20.0. Such film allows for sealing of the film at a reduced temperature, whilst still providing a desirable seal strength, and a desirable hot-tack strength.
