Abstract
The present invention relates to a package comprising a bi-directionally oriented polyethylene film, wherein the bi-directionally oriented film comprises a polymer having moieties derived from ethylene and moieties derived from 1-hexene, wherein the polymer has: (a) a density of ≥910 and ≤930 kg/m3, preferably ≥916 and ≤925 kg/m3, as determined in accordance with ASTM D792 (2008); (b) a melt mass-flow rate of ≥0.2, preferably ≥0.5 or ≥0.6, and ≤5.0 g/10 min, as determined in accordance with ASTM D1238 (2013) at a temperature of 190° C. under a load of 2.16 kg; (c) a fraction that is eluted in analytical temperature rising elution fractionation (a-TREF) at a temperature ≤30.0° C. of ≥8.0 wt %, preferably ≥11.0 wt %, with regard to the total weight of the polymer; and (d) a fraction eluted in a-TREF at a temperature >94.0° C. of ≥20.0 wt %, with regard to the total weight of the polymer; and preferably (e) a fraction eluted in a-TREF at a temperature >30.0° C. and ≤94.0° C. of ≥40.0 and ≤64.0 wt %, with regard to the total weight of the polymer; wherein the package is a bag or pouch containing at least one seal obtained by thermal sealing of two layers of the polyethylene film. Such package allows for handling, in particular opening, in a controlled way such that when a tear is introduced to open the package, that tear can be introduced in a controlled line.
