W202 Vapor Permeable Membrane Tester
Functions
To test the water vapor transmission rate (WVTR) of packaging materials, such as plastic film, composite film, coextrusion film, aluminum-plated film, aluminum foil, infusion bag, sheets, paper, paper board, solar battery panel, cellophane, ceramics and porcelain, and various containers such as bag, pouch, bottle, can, bowl, box, widely used in the industries of food, pharmaceuticals, personal care, household, electronics and so on.
Vapor Permeable Membrane Tester
Standards
GB/T 21529, ISO15106-3, DIN 53122-2, YBB00092003
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
Electrolytic detection sensor method. Fix the test sample in the middle of test chamber to separate the chamber into upper room and lower room. When humid gas flows in upper room and dry gas in lower room, the water molecules in upper room penetrate through the sample into the dry gas, and electrolytic sensor system detect and analyze the water content and calculate the water vapor transmission rate.
