    摘要： The invention relates to a polyethylene laminate film comprising an inner surface and an outer surface and comprising a print film comprising an outer layer E, a core layer F and an inner layer G, wherein the inner layer G forms the outer surface of the laminate film, and wherein the inner layer G is made of an inner layer G composition comprising a component AG, which is an ethylene copolymer having a density of 920 to 935 kg/m 3 and a melt flow rate (MFR 2 ) of 0.5 to 2.0 g/10min, determined according to ISO 1133; and a sealant film comprising an outer layer A, a core layer B and an inner layer C, wherein the inner layer C forms the inner surface of the laminate film, and wherein the inner layer C is made of an inner layer C composition comprising at least one ethylene polymer; wherein the outer layer A of the sealant film is laminated to the outer layer E of the print film, and wherein the seal initiation temperature (SIT) at 5 N of the outer surface of the laminate film is at least 10 °C higher than the seal initiation temperature at 5 N of the inner surface of the laminate film, the seal initiation temperature being determined according to ASTM F2029 and ASTM F88.
    The invention further relates to an article comprising the polyethylene laminate film and to the use of polyethylene laminate film for packaging of an article. Moreover, the invention relates to a sealant film, an article comprising the sealant film and the use of the sealant film for packaging of an article.

    摘要： The present invention relates to a foamed polypropylene composition comprising
    (A) from 60.0 to 95.0 wt% of a propylene homopolymer and
    (B) from 5.0 to 40.0 wt% of a low density polyethylene,
    based on the total weight of the polypropylene composition,
    wherein the polypropylene composition before foaming has a melt flow rate MFR 2 of from 0.1 to 5.0 g/10 min, determined according to ISO 1133 at a load of 2.16 kg and a temperature of 230°C, and a F 30 melt strength of from 0.1 to 2.0 cN, determined according to ISO 16790:2005,
    a sheet comprising said foamed polypropylene composition, an article comprising said sheet, a process for producing said sheet and the use of said foamed polypropylene composition or said sheet for producing an article.

    摘要： The present invention relates to a polymer pipe having a relative eccentricity of at least 0.03, whereby the relative eccentricity (e r ) is defined as follows e r = S max - S min S max + S min
    wherein
    S max
    is the maximum wall thickness of the pipe; and
    S min
    is the minimum wall thickness of the pipe,

    to a process for the preparation of such a pipe and the use of such a pipe for the transport of pressurized fluids.
