▎ 摘　　要

NOVELTY - Producing a food packaging barrier film involves providing a base film, depositing an inorganic laminated film on a surface of the base film, where the inorganic laminated film includes at least one first inorganic material deposition layer and a second inorganic material deposition layer stacked upon each other, and the at least one first inorganic material deposition layer and the second inorganic material deposition layer are formed in a same vacuum deposition process and in a vacuum condition, and where the at least one first inorganic material deposition layer and the second inorganic material deposition layer are respectively formed by different inorganic metal oxides in the same vacuum deposition process, and coating a barrier coating solution on the inorganic laminated film and then curing the barrier coating solution to form a barrier coating layer. USE - Method for producing a food packaging barrier film used for consumers to clearly see the content of the packaged goods. ADVANTAGE - The method enables to produce food packaging barrier film that has a lower material cost, high transparency, a low haze, and excellent water and oxygen barrier properties, so that the applicability of the food packaging barrier film can be increased. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a food packaging barrier film, which comprises a base film, an inorganic laminated film formed on a surface of the base film, where the inorganic laminated film includes at least one first inorganic material deposition layer and a second inorganic material deposition layer stacked upon each other, and the at least one first inorganic material deposition layer and the second inorganic material deposition layer are formed in a same vacuum deposition process and in a vacuum condition, and wherein the at least one first inorganic material deposition layer and the second inorganic material deposition layer are respectively formed by different inorganic metal oxides in the same vacuum deposition process and a barrier coating layer formed on the inorganic laminated film, where the barrier coating layer is formed by coating a barrier coating solution on the inorganic laminated film and then curing the barrier coating solution.
