  • Publication number: 20240083148
    Abstract: Package for storing frozen matter, preferably food products, comprising a laminated film, wherein the laminated film comprises at least a first layer and a second layer, wherein: the first layer is a bi-directionally oriented polyethylene film layer; and the second layer is a second polyethylene film layer; wherein the package comprises ?90.0 wt % of polyethylene with regard to the total weight of the laminated film. Such package demonstrates a desirably high impact strength at temperatures below 0° C., such as at ?25° C., and presents a mono-material solution allowing suitable further processing of the package via recycling technologies.

  • Publication number: 20240066845
    Abstract: The present invention relates to a laminated polyethylene film comprising: (a) a first film; and (b) a second film; wherein the first and the second film are adhering to one another to form a laminate; wherein ? the first film is a bi-directionally oriented film; and ? the second film is a blown film; wherein the first film comprises or consists of polyethylene, and the second film comprises or consists of polyethylene; wherein the second film comprises one or more film layers, and comprises a sealing layer so that the sealing layer forms a surface layer of the laminated film; wherein the sealing layer comprises a polyethylene copolymer (I) comprising moieties derived from 1-octene, having: ? a density of ?855 kg/m3 and ?910 kg/m3, as determined in accordance with ASTM D792 (2008); ? a melt mass-flow rate of ?0.2 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.

  • Patent number: 9902845
    Abstract: The invention relates to linear low density polyethylene having a density in the range from about 900 kg/m3 to less than about 940 kg/m3 as determined using IS01872-2, having a molecular weight distribution (Mw/Mn) in the range from 2.5 to 3.5, having an area under the peak in the temperature range from 20 to 40° C. determined using an analytical temperature rising elution fractionation analysis using 1,2-dichlorobenzene and a heating rate of 1° C./min, wherein the area is in the range from 5 to 20% of the sum of the areas under all peaks determined with the analytical temperature rising elution fractionation analysis.

  • Patent number: 9321864
    Abstract: The present invention relates to a catalyst composition for the polymerisation of olefins comprising a support containing a single site catalyst component, a catalyst activator and a modifier wherein the modifier is the product of reacting an aluminum compound of general formula AI(R1, R2, R3) with an amine compound of general formula N(R4, R5, R6). The catalyst composition reduces fouling and/or sheeting when used to catalyse the polymerisation of olefins. The present invention also relates to a method for the polymerisation of olefins using the catalyst composition of the invention.
