<P>PROBLEM TO BE SOLVED: To provide a package body where edible oil is charged in a transparent plastic container, preventing invasion of water content or oxygen through a container wall during long storage, and preventing reduction in commercial value of the edible oil due to generation of cloudiness and deterioration. <P>SOLUTION: The package body comprises vegetable edible oil charged in a transparent and multi-layer plastic container. The plastic container comprises a multi-layer plastic one having water vapor permeability of at least 1.0g/m<SP>2</SP>× the number of days, and oxygen permeability of 0.05 ml/day × the number of bottles. The plastic container comprises a multi-layer polyester draw-stretched container having at least three-layer structure comprising a polyester resin outer layer/an intermediate resin layer/a polyester resin inner layer. The plastic container has the followings: an oxygen absorbing layer in each of thermoplastic resin inner and outer layers, and a thermoplastic resin intermediate layer; at least a first layer comprising amorphous or low-crystallization polymer of at least olefin and cyclic olefin, and a second layer comprising oxygen-barrier thermoplastic resin; the polyester outer layer, the intermediate layer comprising oxygen-barrier thermoplastic resin, and the inner layer comprising polypropylene resin; and a thermoplastic resin layer and a vapor deposition film layer. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
