    • PURPOSE: A food container manufacturing method of is provided to prevent stain generated as food is adhered on a surface of a food container and to reduce food residue remaining on the food container. CONSTITUTION: Multiple nanostructures (20) is formed on a surface of a food container (300) in contact with food (60). A first hydrophobic film (30) is coated on an upper side of the surface where the nanostructure is formed. A gas barrier (40) is formed between the surface of the food container and the first hydrophobic film. A contact angle of the first hydrophobic film is 90 degrees or greater, and a contact angle hysteresis thereof is less than 30 degrees. The sum of thicknesses of the first hydrophobic film and the gas barrier is equal to or less than a half of a height of the nanostructure. A second hydrophobic film (50) is formed between the surface of the food container and the gas barrier. The nanostructure is formed of at least one form selected from a nanofiber, a nanorod, a nanodot, and a nanowire. The nanostructure has a width of 1 to 100 nm and a height of 1 to 1000 nm.
    • 目的:提供一种食品容器的制造方法,用于防止食品附着在食品容器的表面上产生的污渍,并减少残留在食品容器上的食物残留物。 构成:在与食物(60)接触的食物容器(300)的表面上形成多个纳米结构(20)。 第一疏水膜(30)涂覆在形成纳米结构的表面的上侧。 在食品容器的表面和第一疏水膜之间形成气体阻隔物(40)。 第一疏水膜的接触角为90度以上,其接触角滞后小于30度。 第一疏水膜和气体屏障的厚度之和等于或小于纳米结构高度的一半。 在食物容器的表面和气体屏障之间形成第二疏水膜(50)。 纳米结构由选自纳米纤维,纳米棒,纳米点和纳米线中的至少一种形式形成。 纳米结构的宽度为1〜100nm,高度为1〜1000nm。
