Challenges in Testing Oxygen Permeability of Bottles

Traditional Testing has many Limitations. For example, film-based testing doesn't reflect actual bottle properties due to manufacturing variations. Packages come in various shapes and sizes, making testing difficult. Laboratory temperature needs to be strictly controlled.

ASTM F1307-02 standard for oxygen transmission rate states an alternative test method using a coulometric sensor. This method involves exposing the outside of a package to a known oxygen concentration while purging the inside with nitrogen. By applying different sealing methods, various types of package can be tested (bottles, pouches, etc.).

Labthink C230H Oxygen Transmission Rate Test System is designed and manufactured based on the coulometric sensor method. This instrument offers dual testing capabilities for films and packages. The unique fixing structure allows for strong sealing around container openings.

As the demand for functional packaging materials grows, testing methods are evolving to ensure a more comprehensive evaluation of packaging films.
