Determination of the nitrogen gas transmission rate (N2GTR) of ethylene vinyl alcohol copolymer, using a newly developed permeation measurement system

The oxygen (O2) barrier properties of ethylene vinyl alcohol copolymer (EVOH) have been widely investigated, but for other gases the available data are usually limited to dry conditions due to limitations in measurement equipment. Innovative permeation measurement systems with low detection limits a...
