Two of the most important and widely used test method and standard used in food packaging industry used to establish barrier properties and thus shelf-life expectations this are the Oxygen Transmission Rate (OTR) and Moisture Vapor Transmission Rate (MVTR). What is OTR? Oxygen Transmission Rate (OTR) is the measurement of the amount of oxygen . The film with 12 µm glass layer exhibits a water vapor transmission rate of 5.7 × 10⁻⁴ g m⁻² day⁻¹, and an oxygen transmission rate of 1.46 × 10⁻⁴ g m⁻² day⁻¹, which is 5 . Of interest are also basic oxygen transmission rates (OTR) through multi-layer sheets [4] or composite materials [5, 6]. Gas transport can be characterized with different methods [7] and oxygen permeation is investigated with approaches ranging from commonly used coulometric [1, 8] and galvanic [5] to fluorescence quenching sensing [9, 10]. Each module contains two test cells and is available in master and satellite configuration.
