    Abstract: An infrared shielding film and a method for manufacturing the same are provided. The infrared shielding film includes an infrared absorbing layer and a first infrared reflecting layer disposed on a surface of the infrared absorbing layer. The infrared absorbing layer contains a uniform distribution of composite tungsten oxide particles that are present in an amount of 0.1% to 10% by weight based on the total weight of the infrared absorbing layer. The first infrared reflecting layer contains a uniform distribution of titanium oxide particles that are present in an amount of 0.1% to 10% by weight based on the total weight of the first infrared reflecting layer.

    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.
