Abstract of the Disclosure Disclosed is a plastic bottle comprising as a wallforming component a layer of a copolymer consisting essentially of 99 to 70 % by weight of vinylidene chloride and 1 to 40 % by weight of at least one acrylic or methacrylic monomer and further including up to 100 parts by weight of at least one member selected from other ethylenically unsturated monomers per 100 parts by weight of the total amount of said two monomers, said copolymer having an oxygen permeability constant of less than 9 x 10-14 cc-cm/cm2-sec-cmHg as measured at a temperature of 20°c and a relative humidity of 100 % and a water vapor permeability constant of less than 3 x 10-3 g.cm/m2-day as determined according to the method of JIS Z-0208. This plastic bottle is obtained by casting an aqueous latex of the like of the above-mentioned copolymer in a bottle mold and drying the cast latex. This aqueous latex may be formed as a coating layer on a preformed plastic bottle. In this plastic bottle, the humidity dependency of the oxygen barrier property is prom- inently reduced.
