摘要： 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.
