Multilayered article, vessel and resin composition based on polyethylene

摘要

A multilayered article and vessel, which are superior in the properties, such as shock resistance, rigidity, an ability to barrier against gasoline and interlayer adhesion, and are permissible of being recycled for reuse, comprising a base layer (A1) comprising a polyetylene resin (a1) having an MFR (ASTM D 1238, 190 DEG C, 2160 g) of 0.001 to 0.5 g/10 min. and a density of 0.945 to 0.980 g/cm<3>, an adhesive layer (A2) comprising a modified etylene/ alpha -olefin copolymer (a2) which is modified by having grafted thereon an unsaturated carboxylic acid or its derivative and has a density of 0.900 to 0.940 and a barriering layer (B) comprising an ethylene/vinyl alcohol copolymer (b), wherein the Izod impact strength (with notch) (ASTM D 256, -40 DEG C ) for a sheet specimen which is prepared by mechanically crushing the laminate into powder, granulating the resulting powder on a monoaxial extruder to form a resin composition and pressing the granular composition on a press molding machine into a sheet of 3 mm thickness at a temperature of 230 DEG C under a pressure of 50 kgf/cm<2> with cooling under the condition defined by ASTM D 1928, is at least 100 J/m.
