Abstract: A method for producing a laminated body including a base material and a coating layer laminated on the base material, includes: applying a coating liquid containing cellulose nanofibers onto the base material composed of at least acid-resistant paper, thereby forming the coating layer. In addition, an average fiber diameter of the cellulose nanofibers is 2 nm or more and 2000 nm or less, a content of the cellulose nanofibers in the coating liquid is 10 mass % or more of solid contents of the coating liquid, and a coating amount of the coating layer is 0.2 g/m2 or more in dry mass.

Abstract: A paper cup includes barrier paper, the barrier paper including at least a paper base material, a reinforcing layer containing cellulose nanofibers which is formed on the paper base material, and a sealant layer formed on the reinforcing layer, in which after the paper cup is caused to free-fall 5 times towards a concrete floor surface from a height of 1 m with the bottom portion being disposed downward, the paper cup has a buckling strength of 350 N or more in a case of being sandwiched between two parallel plate surfaces and compressed in a height direction of the body portion, and has a lateral pressing strength of 4 N or more in a case where the body portion is pressed by 10 mm at a ⅔ height, from a bottom, of the entire height of the paper cup.
