WVTR Testing, Water Vapor Transmission Rate Testing

Water vapor transmission rate (WVTR) also known as moisture vapor transmission rate is the process of measuring the amount of water that can permeate 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 WVTR by creating a moisture gradient from one side of the film to the other that allows the moisture to pass through the material and measures the permeation value.  

WVTR testing is important in the flexible packaging industry because it ensures that food products maintain the necessary amount of moisture within their package: not too dry, not too moist, just right!

Flex-Pack Engineering provides WVTR 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 moisture permeation value for a particular package. Additionally, we can provide WVTR Testing as part of the design and development process to evaluate if a new film material has a better WVTR than the previous film design. We also help customers who are having issues with the WVTR of a particular film and assist in tracking down the problem and offering recommendations for a solution.

Flex-Pack Engineering offers very competitive WVTR Testing rates and turnaround times. However, the most important element that Flex-Pack offers our customers is the interpretation of WVTR 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 WVTR testing results with our customers to make sure they understand the data and how it effects the overall product design.
