Barrier resin film, barrier laminate, and packaging material using the barrier laminate

摘要

To provide a barrier resin film having excellent barrier properties without adopting a multilayer structure as in the prior art.MEANS FOR SOLVING THE PROBLEM: There is provided a barrier resin film in which an aluminum oxide deposition film is formed on the surface of a resin substrate, wherein an element bond structure part represented by Alis distributed in the aluminum oxide deposition film and the intensity ratio Al/AlO×100 of a maximum Alconcentration element bond structure part in time-of-flight secondary ion mass spectrometry (TOF-SIMS) is 5 or more and 50 or less.SELECTED DRAWING: Figure 1
