<p>PURPOSE:To obtain a plastic molded container having excellent barrier capacity against methanol mixed gasoline by forming a wall part by mutually bonding and laminating a specific barrier layer, an adhesive layer and a polyethylene layer in this order from the outside. CONSTITUTION:A wall part is constituted by mutually bonding a polyphenylene sulfide layer (PPS layer), an adhesive layer and a polyethylene layer in this order from the outside. Herein, polyphenylene sulfide is a polymer containing 70mol% or more, pref., 90mol% or more of a predetermined repeating unit. When the repeating unit is below 70mol% or less, no pref. effect is obtained because the heat resistance of PPS is damaged. Since PPS has an m.p. higher than that of polyethylene, the use of PPS as the outermost layer is advantageous, for example, from a cooling aspect at the time of molding and processing becomes easy.</p> |
