  • Publication number: 20240075716
    Abstract: The present invention relates to a bag comprising a film, wherein the film comprises at least a first layer, wherein the first layer is a bi-directionally oriented polyethylene film layer, wherein the bag comprises ?90.0 wt % of polyethylene with regard to the total weight of the film. Such bag may be used for packaging of bulk goods or for packaging of frozen matter. Such bag demonstrates a desirably high retention of mechanical properties and shape under load, at reduced weight as compared to bags of the art, and presents a mono-material solution allowing suitable further processing of the bag via recycling technologies.

  • Publication number: 20180171125
    Abstract: The present invention relates to a polymer composition comprising a linear low-density polyethylene produced in the presence of a single-site catalyst system and 0.01-2.00% by weight of a nucleating agent, the linear low-density polyethylene having a density as determined according to ISO 1183-1 (2012), method A of >900 kg/m3and ?940 kg/m3, wherein films produced using the polymer composition have a total defected area of ?50 ppm of surface, the total defected area being the fraction of surface area of the film accounted for by gels having an equivalent diameter of >50 ?m. Such polymer compositions are suitable for the production of films having a low oxygen transmission rate and a low water vapour transmission rate.
