Abstract
This invention relates to a polyester/polyamide blend having an excellent gas barrier property and an improved flavor retaining property and clarity. More particularly, the present invention relates to a polyethylene terephthalate/low molecular weight polyamide blend having an excellent gas barrier property, in which by reducing the concentration of acetaldehyde contained in the polyester, the storage property of a food or the like and the flavor-retaining property and fragrance retaining property are highly improved without producing haze.
