摘要： An object of the present invention is to provide an inexpensive transparent barrier film which uses a plastic film prepared using a recycled resin of PET bottles in consideration of the environment and has excellent acid resistance. A transparent gas barrier film includes an aluminum oxide layer mainly composed of aluminum oxide on at least one surface of a substrate polyester film. The absorption coefficient immediately after vapor-deposition of the aluminum oxide layer is less than 0.03 nm -1 . The vapor-deposition film thickness of the aluminum oxide layer is 6 nm or more and 10 nm or less. The substrate polyester film is a biaxially stretched polyester film containing 50% by weight or more of a polyester resin obtained by recycling PET bottles. A content of isophthalic acid, an intrinsic viscosity, a heat shrinkage rate, lamination strength, and thickness unevenness are within predetermined ranges.

摘要： [Problem] To provide a method for manufacturing a processed plastic film, the method comprising a charge removal step for preventing damage to a charged plastic film due to abnormal discharge and eliminating problems with plastic film travel due to electrostatic adhesion by removing the charge on the plastic film using a simple device and lowering the potential at the surface.
[Solution] The problem can be solved by a method which is for manufacturing a processed plastic film and reduces the amount of charge on a plastic film traveling in a vacuum, the method comprising a step (step 1) for removing charge by a charge removal method in which a conductor having a radius of curvature of 1 mm or less is installed near the plastic film in the width direction of the plastic film, the shortest distance between the surface of the plastic film and the conductor is set to 2-10 mm, and the grounded conductor is used while maintaining the pressure therebetween at 8-800 Pa.-

摘要： A method and apparatus for producing a long transparent barrier film, which has stable barrier properties and color by stably adjusting the degree of oxidation and the film thickness to desired values, comprises a step for producing a transparent gas barrier film which has, on at least one surface of a plastic film, an aluminum oxide layer that is mainly composed of aluminum oxide or a silicon oxide layer that is mainly composed of silicon oxide, said aluminum or silicon oxide layer being produced by evaporating aluminum metal or silicon metal and injecting oxygen thereinto. In this step, the film thickness of the thus-formed aluminum oxide layer or silicon oxide layer is measured by a film thickness gauge using X ray fluorescence and the light transmittance of the thus-formed aluminum oxide layer or silicon oxide layer is measured by a light transmittance measuring device so as to control the film thickness and the light transmittance to be at predetermined values.
