WVTR Water Vapor Transmission Rate

Standards

ASTM E96

Application :

* Films
rigid films, shrik films, stretch films, plastic films, plastic composite films, paper-plastic composite films,aluminized films, aluminum foil, aluminum composite films, high barrier films and many others. Eg. PET, OPP, CPP, LDPE, BOPP

* Sheet
engineering plastics, rubber, waterproof building materials, and thermal insulation materials, e.g. PP, PVC, PVDC, and nylon

*Packages
paper, plastics, rubber,paper-plastic composite, glass, and metal packages, eg: bottles, containers

Working principle

Gravimetric method. Fix the test sample in the middle of test chamber to separate the chamber into upper room and lower room; humid gas flows in upper room, and place desiccant device in lower room; as in lower room it remains dry (0-8%RH) by desiccant, water molecules penetrate through the sample from upper room into lower room, absorbed by desiccant; then the cup weight will increase; system weigh the increasing cup weight so as to calculate the water vapor transmission rate.
