Permeation Testing Services – Fast & Affordable
Permeation testing is the process of analyzing a substrate to determine how much of a certain type of gas or liquid can pass through a substrate per unit time. Oftentimes our customers need to know how much of a liquid or gas will pass through a flexible packaging material in the design and development of their packaging products.
Primarily Flex-Pack Engineering provides the following permeation testing services:
MVTR Testing – Moisture Vapor Transmission Rate Testing
Moisture vapor transmission rate (MVTR) also known as water vapor transmission rate (WVTR) 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 MVTR by creating a moisture gradient from one side of the film to the other that allows the moisture to pass through the material and measure the permeation value. For more information on our MVTR Testing, check out our article “MVTR Testing – Moisture Vapor Transmission Rate Testing” in our Learning Center.
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. We 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. For more information on our OTR Testing services, check out our article “OTR Testing – Oxygen Transmission Rate Testing” in our Learning Center.
Additionally, other types of permeation testing services Flex-Pack Engineering provide include CO2 testing, and ethylene testing.
Why Choose Flex-Pack Engineering for Permeation Testing Services?
In today’s fast-paced world, companies need testing results quickly. Flex-Pack has invested in state-of-the-art testing equipment infrastructure to expand our capabilities to provide test results quickly. We have multiple testing units available for permeation testing and can provide results faster than the industry standard.
