WVTR and OTR testers: frequently asked questions
What is the difference between WVTR and OTR testing?
WVTR is water vapor transmission rate and OTR is oxygen transmission rate. The GBPI W301 2.0 measures WVTR by the gravimetric (weight-loss) method, while the Y110 2.0 measures OTR with a high-precision imported coulometric sensor.
Which standards do the W301 2.0 and Y110 2.0 follow?
WVTR: GB/T 1037, GB/T 16928, ASTM E96/E96M, ASTM D1653, TAPPI T464, ISO 2528, DIN 53122-1, JIS Z0208 and YBB 00092003. OTR: GB/T 19789, ASTM D3985, ASTM F1927, ASTM F2622, ISO 15105-2, DIN 53380-3, JIS K-7126-B and YBB 00082003.
What measuring ranges do the WVTR and OTR testers cover?
The W301 2.0 covers 0.1–10,000 g/(m²·24h) with 0.0001 g/(m²·24h) precision over a 50.24 cm² test area. The Y110 2.0 covers 0.01–1,000 cm³/(m²·24h·0.1MPa), up to 260,000 with a mask, at 0.0001 resolution. Temperature is controlled to ±0.1 °C on both.
Which materials can be tested?
Films (PP, PET, PE, PVC, BOPP, CPP, composite, co-extruded, aluminized and degradable PLA/PBAT/PBS), sheets, paper and cardboard, medicinal patches, pharma and consumer packaging, hygiene products, rigid packaging, solar backsheet and pipes.
