    摘要： A hollow multi-layer molding made of a multi-layer laminate material, the multi-layer laminate material having: a polyethylene layer; a barrier layer made of a substance selected from the group consisting of polyamide resins, saponified derivatives of ethylene-vinyl acetate copolymers, thermoplastic polyesters, and a mixture of at least two of the polyamide resin, the saponified derivative and the thermoplastic polyesters; and an adhesive layer made of a modified polyolefin resin, the polyethylene layer and the barrier layer being laminated to each other with the adhesive layer sandwiched therebetween. The polyethylene layer is made of a high-molecular-weight polyethylene which is obtained by using a specific chrome catalyst and a reducing agent, and which has a high-load melt flow rate (at a temperature of 190.degree. C. under a load of 21.6 kg) of 1 to 10 g/10 min., and a density of not less than 0.935 g/cm.sup.3. The hollow multi-layer molding has excellent barrier properties with respect to vehicle fuels and excellent mechanical strength, such as impact strength, and is capable of being produced while allowing improved reclaiming of flash and the like.
