JIS K 7361 Barrier Properties Testing of Plastic Storage Plastics
The JIS K 7361 standard is an essential tool for quality managers, compliance officers, R&D engineers, and procurement specialists working in the polymer & plastics sector. This test evaluates barrier properties such as gas permeability, moisture vapor transmission rate (MVTR), and oxygen permeability of plastic materials used in storage containers.
This testing service ensures that storage containers maintain their integrity over long periods under various environmental conditions. Understanding these properties is critical for preventing contamination or spoilage of the contents being stored, which can lead to significant financial losses and reputational damage.
The JIS K 7361 standard applies specifically to plastic containers used in food packaging, pharmaceuticals, and other industries where maintaining the integrity of the product is paramount. By conducting this test, manufacturers can ensure that their products meet regulatory requirements and industry standards, thereby enhancing consumer trust and safety.
Our laboratory uses state-of-the-art equipment and adheres strictly to JIS K 7361 guidelines to provide accurate results. This ensures that customers receive reliable data on the barrier properties of their plastic storage containers, enabling them to make informed decisions about material selection and packaging design.
The testing process involves several steps, including specimen preparation, conditioning, and measurement. Specimens are typically prepared from commercially available materials or custom samples provided by clients. Once prepared, specimens undergo conditioning to ensure they reach a stable state before testing begins.
Testing equipment includes chambers designed to control temperature, humidity, and gas composition, ensuring accurate measurements of barrier properties under controlled conditions. During the test, gases such as oxygen, nitrogen, carbon dioxide, and water vapor are passed through the specimen, and their concentrations on either side of the material are measured using sensitive analytical instruments.
The results provide a comprehensive understanding of how well the plastic container can protect its contents from environmental factors. This information is vital for optimizing packaging design, selecting appropriate materials, and ensuring compliance with relevant regulations.
| Parameter | Description |
|---|---|
| Oxygen Permeability (OP) | The rate at which oxygen passes through the material over time. This is crucial for preserving freshness in food products and preventing oxidation. |
| Moisture Vapor Transmission Rate (MVTR) | The amount of moisture that can pass through the material, which affects the shelf life of packaged goods. |
| Water Vapor Permeability (WVP) | A measure of how much water vapor can permeate the material. This is important for packaging materials in humid environments. |
| Carbon Dioxide Permeability (COP) | The rate at which carbon dioxide passes through the material, affecting the freshness and quality of packaged products. |
Understanding these parameters allows for the optimization of packaging design to meet specific product requirements. For instance, if a container needs to protect perishable goods from both moisture and oxygen, selecting a material with high barrier properties in both areas becomes crucial.
The JIS K 7361 test is not just about protecting products; it also plays a vital role in ensuring that packaging complies with environmental regulations. By minimizing the use of resources such as plastic films while maintaining product integrity, manufacturers can contribute positively to sustainability efforts.

Our experienced team works closely with clients to ensure that all aspects of the test are conducted accurately and efficiently, providing reliable data for informed decision-making.
Scope and Methodology
| Test Methodologies | Description |
|---|---|
| Oxygen Permeability (OP) | The test involves measuring the amount of oxygen that can pass through the material over time. Specimens are exposed to a controlled environment with known concentrations of oxygen, and changes in concentration on either side of the material are measured using gas analyzers. |
| Moisture Vapor Transmission Rate (MVTR) | This test evaluates how much moisture can pass through the material by exposing it to a humid environment. Changes in weight or humidity levels on either side of the specimen are recorded and used to calculate MVTR. |
| Water Vapor Permeability (WVP) | Similar to MVTR but focuses specifically on water vapor. This test is particularly useful for packaging materials that come into contact with moisture, such as food or pharmaceutical products. |
| Carbon Dioxide Permeability (COP) | The rate at which carbon dioxide passes through the material is measured by exposing it to a controlled environment and monitoring changes in concentration on either side of the specimen. |
The testing process begins with selecting appropriate specimens that represent the materials used in production. These samples are conditioned according to JIS K 7361 requirements before being subjected to the barrier tests described above. Specimens may be prepared from commercially available materials or custom samples provided by clients.
Once tested, results are compiled into detailed reports that outline each parameter's performance. These reports serve as valuable tools for quality assurance teams and R&D departments in optimizing product design and ensuring compliance with relevant standards.
The accuracy of the test results depends heavily on proper specimen preparation, conditioning, and adherence to JIS K 7361 guidelines throughout the testing process. Our laboratory ensures that all these factors are meticulously controlled to deliver reliable data.
