PROBLEM TO BE SOLVED: To provide a film as a packaging material that has excellent transparency, allows its contents to be seen through, is applicable to a metal detector, has a high gas barrier function, and is particularly suitable for blocking alcohol permeation.SOLUTION: A gas barrier laminate film is formed by putting a gas barrier vapor deposition layer and a gas barrier coating layer on a resin base material, the gas barrier vapor deposition layer mainly composed of an inorganic compound, and the gas barrier coating layer obtained by the application of a coating liquid followed by drying, the coating liquid comprising one of a silicon compound represented by general formula Si(OR)(1) and hydrolysate thereof, one of a silicon compound represented by general formula (RSi(OR))(2) and hydrolysate thereof (in the general formulas (1) and (2), Rand Rrepresent CH, CH, or CHOCH, and Rrepresents an organic functional group), and a water-soluble polymer having a hydroxy group. |
