Barrier property is a characteristic of hollow containers and can be used to meet the need for shelf life of the contents; the hollow container shape is variable, which makes it difficult for overall barrier property testing. Based on this, this paper discusses the common testing methods of water vapor barrier property of hollow containers. Firstly, the advantages and disadvantages of the traditional weighing method and sensor method in testing the water vapor barrier property of containers are compared, typical applications are taken as an example, and finally two new methods, namely electrolytic sensor method and infrared sensor method, which can quickly and accurately test the moisture permeability of hollow containers, are introduced in detail, so as to achieve good and accurate test for various hollow containers, which can provide reference for related industries in selecting testing technologies for container barrier property.
