Automatic Water Vapor Permeability Analyzer for Film , Aluminum Foil etc.
Application
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
Weight reduction method (wet cup method). Seal the cup with test sample, keep humidity difference between inside and outside of the cup, and water vapor will penetrate the test sample; monitor the change of cup weight to calculate transmission rate.
Configuration
Water Vapor Permeability Analyzer test the water vapor transmission rate of various materials, including: plastic film, composite film, aluminum-plated film, aluminum foil etc.; packaging containers, such as bag, bottle, bowl, can etc.; sheets, such as PP sheet, PVC sheet, rubber, building material, porcelain; other application, such as solar panel, paint film, medical patch etc. It is widely used in packaging, plastic film, food, pharmaceuticals, personal care industries, inspection agency, research institute, college and so on.
Standards
GB 1037, GB/T 16928, ASTM E96, ASTM D1653, TAPPI T464, ISO 2528, DIN 53122-1, JIS Z0208, YBB00092003, YBB00022002, YBB00112005, YBB00102005
