Food packaging barrier film and method for producing the same
Abstract:
A food packaging barrier film and a method for producing the same are provided. The method includes providing a base film, depositing an inorganic laminated film on a surface of the base film, and coating a barrier coating solution on the inorganic laminated film and then curing the barrier coating solution to form a barrier coating layer. 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. 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 depositing process.
