Japan's Development of Oxygen Transmission Rate Measuring Devices

In recent years, the need for oxygen permeability measurement and inspection of packaging materials and containers for foods and beverages has been much greater than it was a few years ago. The main reason is the diversification of the packaging materials used and the materials of the containers. In order to differentiate the company's products from those of other companies, each of the Japanese Oxygen Permeability Tester production companies used a small-sized PET and a heat-resistant PET packaging container in order to diversify their packaging forms and methods. A few years ago, a major food poisoning accident occurred at a dairy company in Japan and it was initially thought that it was caused by incomplete packaging of paper containers. Later, although it was discovered that the cause of accidents caused by factory temperature management mistakes, but as a lesson learned, many Japanese food production companies and packaging companies began to strengthen the analysis and measurement of packaging oxygen permeability from the perspective of the company's own defense.

Today, Japan's major packaging film and packaging container manufacturing companies and food companies are investing in additional oxygen permeability measurement devices. At present, the Oxygen Permeability Tester of Moscox Japan occupies most of the market. In order to closely follow the drastic changes in the food and beverage industry, it is necessary to invest in additional oxygen permeability measurement devices. Therefore, the market for oxygen permeability measuring devices is promising.

However, the market price of the device is as high as 10 to 20 million yen, which is a great economic burden for small and medium-sized food and packaging companies. Therefore, a low-cost measuring device that closely follows Mocco's equipment has emerged in the market to cater to the needs of SMEs. This complementary competition in the market has further promoted the development of oxygen transmission rate analysis devices and increased market transactions.

Hitachi Tektronix, Inc. operates the Oxygen Transmittance Measuring Device “OX-TRAN 2/21” manufactured by Moscox Co., Ltd., which is a device that complies with the Japanese Industrial Standard (JIS) K-7126B and has an absolute advantage in the market. It has a large market share and is used in more than 60 countries in the world.

The device uses a unique coulometric sensor that prevents the sensor from deteriorating early through the self-contained humidification function of the device and reacts only to oxygen. The sensor provided in the device can detect trace amounts of oxygen even in the presence of water vapor.

At the same time, the product has a rich variety of specifications and models to create series, according to the different needs of customers to form an analytical measurement system. Various parameters such as the measurement time and temperature of the series measurement device can be controlled by the computer.

Japan's Westerhäger Hagner operates an oxygen transmission rate measuring device “Model800” produced by the American Illinois company. Because the device uses a unique sensor that has been patented, it can be measured accurately and quickly. The principle of measurement is the use of isobaric methods that meet the requirements of national standards.

OPT-5000, an oxygen permeability tester operated by the company, uses a high-sensitivity and fast-response zirconia sensor. According to the different sizes, the closed-system constant error or vertical flow meter can be selected separately. The measurement range is very wide, and the sensitivity is good. Before the stable value is obtained, the measurement can be repeated 3-5 times.
