AquaFlex PVOH resins and liquid coatings for film, extrusion coating and paper
Few companies in the world formulate modified PVOH
Modified PVOH resin is made by only a few companies, in a few countries. Since 2022, PVA PRO formulates it in Vietnam, with consistent quality and competitive prices for international converters.
AquaFlex was Vietnam's first modified PVOH resin. We also convert AquaFlex into film on our own lines, so we know how each grade runs in production.

AquaFlex resin and coating questions
Which AquaFlex grade should I use for cold water?
B-CWS dissolves in water above 25°C and runs on blown film lines. For extrusion coating on cardboard or fibre, EX-CWS is the cold water grade.
Can AquaFlex resin run on my existing blown film line?
AquaFlex B grades are made for mono and co-extrusion blown film lines. We usually start with a sample run on your own line with our technical team before quoting volume.
Are AquaFlex coatings approved for food contact?
L-BAR and L-OPV coatings on cardboard passed EU food-contact tests at Eurofins MTS Vietnam in 2024 (reports 76124-100992 and 76124-070071). That scope covers those two coatings on cardboard, not the whole range.
How should AquaFlex resin be stored?
Keep the sealed bags below 30°C and below 50% relative humidity, away from direct sunlight and water.
Where can I get the TDS, MSDS and COA?
Send us the grade and your use at info@pva-pro.com. We send the technical data sheet, the safety data sheet and the certificate of analysis for your batch.
