Oxygen Transmission Rate (OTR) Testing

flexible packaging testing services

OTR Testing, Oxygen Transmission Rate Testing

Oxygen transmission rate (OTR) testing is the process of measuring the amount of oxygen that can pass through a polymer package film or membrane on a square meter basis in 24 hours. Flex-Pack Engineering has the experience and highly specialized instruments which measure OTR by placing 100% pure oxygen on one side of the film and 100% pure nitrogen on the other side of the film. As the oxygen molecules pass through the film, they are caught up in the nitrogen stream and swept off to a detector that counts the oxygen molecules and determines the volume (in CC’s) per unit time.

OTR testing is important in the flexible packaging industry because it ensures that food products maintain their flavor and odor profile. This is important for products such as meats, nuts, or fruits and vegetables that can change or spoil based on the amount of oxygen ingress into the packaging.  

Flex-Pack Engineering provides OTR Testing for customers for a variety of reasons including quality control or to allow a manufacturer to provide a certificate of conformance that certifies the oxygen transmission rate value for a particular package. Additionally, we can provide OTR Testing as part of the design and development process to evaluate if a new film material has a better OTR than the previous film design. We also help customers who are having issues with the OTR of a particular film and assist in determining the problem and offering recommendations for a solution.

Flex-Pack Engineering offers very competitive OTR Testing rates and turnaround times. However, the most important element that Flex-Pack offers our customers is the interpretation of OTR test results and providing recommendations to help solve flexible packaging problems or improve a new film design. A traditional testing lab will deliver testing results but not provide the insights into what the results mean in context of a customers’ goals or issues. With our consultative approach at Flex-Pack, we always discuss OTR testing results with our customers to make sure they understand the data and how it effects the overall product design.

    Flexible Packaging Testing Services That Offer A Competitive Advantage | ASTM, ISO, OTR, MVTR and Much More

    The Need For Comprehensive, Unbiased 3rd Party Flexible Packaging Testing

    For nearly 30 years, Flex-Pack Engineering has been providing unbiased, 3rd party ASTM and ISO flexible packaging testing. We identified a need with our customers to analyze and validate the effectiveness and usefulness of their products in the marketplace, or to help them understand the requirements for entering a new market. For example, a customer may only sell into the potato chip industry but would like to start selling into the frozen chicken or meatball industry. Flex-Pack helps our customers understand the requirements for this new market and provide the testing services to meet the fitness for use and chain of use requirements.

    Perhaps the most important element that Flex-Pack offers our customers is the ability to interpret test results and help them solve their flexible packaging problems. A normal testing lab will deliver testing results but not provide any insights into what the results mean in the context of your problem. In short, it is not the testing that is so important, it is the answers and recommendations to solve the problem and improve your flexible packaging products.

    Additionally, many manufacturing facilities such as film producers, converters, printers, laminators, bag, and packaging converters may not have a packaging engineer and/or full laboratory, or the time for flexible packaging testing. Also, they may need to do testing that is outside the scope of their in-house capabilities.

    Furthermore, some customers may have a good flexible packaging product that they want to make even better to help them compete in the marketplace. Flex-Pack Engineering can offer reverse engineering services including competitive analysis as well as defect analysis and production troubleshooting to help our customers understand why their competitors packaging products outperform their own and make recommendations on how to improve their flexible packaging product.

    Flex-Pack Engineering is able to provide these comprehensive services and help customers gain a competitive advantage in the marketplace.
