Automatic Water Vapor Permeability Analyzer for testing water vapor transmission rate (WVTR) of various packaging materials and containers.

Tests water vapor transmission rate (WVTR) of packaging materials including 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 food, GMP-compliant, personal care, household, and electronics industries.

Weight reduction method (wet cup method). The cup is sealed with test sample, maintaining humidity difference between inside and outside. Water vapor penetrates the test sample while monitoring cup weight changes to calculate transmission rate.

Tests water vapor transmission rate of various materials including plastic film, composite film, aluminum-plated film, aluminum foil; packaging containers such as bag, bottle, bowl, can; sheets including PP sheet, PVC sheet, rubber, building material, porcelain; and other applications like solar panel, paint film, medical patch. Widely used in packaging, plastic film, food, GMP-compliant, personal care industries, inspection agencies, research institutes, and colleges.
