PROBLEM TO BE SOLVED: To provide a polyethylenic molding material having excellent moldability, high fluidity, odors, impact resistance, food safety and excellent gas barrier properties and heat resistance. SOLUTION: The polyethylenic molding material comprises (A) >50 to≤90 wt.% of polyethylene, (B) 5-30 wt.% of an ethylene-vinyl alcohol copolymer and (C) 5-40 wt.% of a modified polyolefin prepared by grafting at least one kind of monomer selected from the group consisting of an unsaturated carboxylic acid and a derivative thereof on a polyolefin. The polyethylenic molding material is characterized in that the molding material satisfies conditions of(1)≥25 cm spiral flow at t=2 mm at 190°C molding temperature and 40°C metal mold temperature, (2) 0.953-1.07 g/cm<SP>3</SP>density, (3)≥4 kJ/m<SP>2</SP>Charpy impact value and (4)≤100 ml×mm/m<SP>2</SP>×day×atm oxygen permeability, respectively.
