Abstract
A hollow plastic article is described, with at least one opening and with a structure which has one or more layers, the hollow plastic article comprising at least one layer made from a polyolefin which was prepared using a fluorine-modified chromium catalyst. The use of hollow plastic articles of the invention as plastic fuel containers, gasoline canisters, plastic tanks, or plastic bottles or the like is also described.
Claims19
A hollow plastic article with at least one opening, wherein the hollow plastic article, whose structure has one or more layers, has at least one layer made from a polyolefin having a density of from 0.943 to 0.955 g/cm3 and a melt flow rate MFR (190° C./21.6 kg) of from 2 to 8 g/10 minutes, prepared using a fluorine-modified chromium catalyst.
A method of producing a hollow plastic article with at least one opening, said method comprising coextrusion blow-molding at least one layer made from polyolefin having a density of from 0.943 to 0.955 g/cm3 and a melt flow rate MFR (190° C./21.6 kg) of from 2 to 8 g/10 minutes, wherein the polyolefin has been obtained using a fluorine-modified chromium catalyst.
