W303 Water Vapor Transmission Rate Tester,Testing equipment,water vapor Permeation analyzer
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.
Working principle:
W303 Water Vapor Permeation Tester was designed with the principle of weighting method to use weight reduction method to test the water transmittance rate (WVTR) of plastic films. Namely in the regulated temperature, relative humidity conditions, the sample two sides keep the vapor different pressure, measuring the vapor volume passed through, figure out the WVTR value. Unit is g/ m2·24h.
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
