ABSTRACT:
A water-resisting and oil-resisting laminated sheet, the oil resistance of which is not reduced by alcohol, prepared by laminating an ethylene-vinyl acetate copolymer layer and a paper, which paper is coated or impregnated with a liquid or a coating composition and then dried by heating. The copolymer layer has a vinyl acetate component of 10 to 30 mole %, a melt flow index of 2 to 20, and a thickness of 10 to 50.mu.. The liquid is in an amount of 0.5 to 5% by weight to the paper as solid component and is prepared by mixing an aqueous solution or an aqueous dispersion of an oil-resisting polymer such as polyvinyl alcohol, etc., with an aqueous dispersion of a perfluoroalkyl acrylate copolymer at 3:7 to 7:3 by solid component ratio, adding thereto 0.1 to 3% by weight of a penetrating agent such as polyalkylene glycol or derivatives thereof, and diluting with water. The coating composition is composed of 100 parts by weight of a reactive silicone-acrylate resin emulsion and 20 to 100 parts by weight of a perfluoroalkyl acrylate copolymer which is diluted with water in an amount of 0.5 to 5% by weight to the paper as solid component. Also, a water-resisting and oil-resisting food-keeping means capable of controlling the diffusing amount of alcohol vapor comprising a bag, at least a part of which is composed of the aforesaid laminated sheet prepared by using a previously printed paper, and an alcohol component enclosed in the bag.
