Abstract
A pulp molded container comprising a pulp molded article (2) having on the inner surface and/or the outer surface thereof a resin layer (3) with a thickness of 5 to 300 μm formed by applying a coating, wherein the thickness ratio of the resin layer (3) to the molded article (2) (former/latter) is 1/2 to 1/100, and the surface roughness profile of the outer or inner surface of the pulp molded article is such that a centerline average roughness (Ra) is 0.5 to 20 μm.
Claims8
A pulp molded container comprising a pulp molded article having on an inner surface and an outer surface thereof a resin layer with a thickness of 5 to 300 pm formed by applying a coating, wherein a thickness ratio of said resin layer to said molded article is 1/2 to 1/100, and a surface roughness profile of the outer surface or the inner surface of said pulp molded article is such that a centerline average roughness (Ra) is 0.5 to 20 μm, wherein said pulp molded article has said resin layer on both the inner surface and the outer surface thereof, the water vapor transmission rate of the resin layer formed on the inner surface and that of the resin layer formed on the outer surface differ by 10 g/(m2.24 hr) or more, and either one of the resin layers has a water vapor transmission rate of 100 g/(m2.24 hr) or less.
