Only a Few Countries Make Modified PVOH: Why Vietnam Is a New Sourcing Alternative

Why so few companies make modified PVOH

Buying PVOH film looks simple until you try to find a supplier who controls the material itself. Making a water-soluble film that runs on a packaging line, survives storage and dissolves at the right temperature takes material formulation, not only film blowing. The solubility of PVA depends on its degree of hydrolysis and polymerisation, and film grades use modified chemistry and additives to reach the properties a converter needs (Chemistry & Chemical Technology, 2023).

That is why only a few companies, in a few countries in the world, can develop modified PVOH material technology. For an international brand, it also means a short list of possible sources, and a supply risk if one of them changes priorities.

Demand for low-impact packaging keeps growing

Brands are looking for materials with better end-of-life options. European Bioplastics reports that packaging remains the largest market segment for bioplastics, at 41.3 percent of the bioplastics market in 2025, and forecasts that global biobased plastics production capacity will roughly double from 2.31 million tonnes in 2025 to about 4.69 million tonnes by 2030 (European Bioplastics market data).

PVOH answers a specific part of that demand: packaging that should dissolve in water, such as pre-dosed detergents, hospital laundry bags and mold release film, and packaging that should not leave a persistent plastic bag behind, such as garment and electronics bags. The applications guide covers each use.

Vietnam as a sourcing alternative

Based in Vietnam, PVA PRO offers international businesses a unique alternative: a reliable partner with good quality and competitive prices. Many brands already source garments, footwear, electronics and furniture in Vietnam, so packaging made in the same country can follow the same supply chain.

Vertical integration, from raw material formulation to finished custom films, shortens lead times for brands sourcing in Vietnam, with guaranteed quality and competitive pricing. PVA PRO produces under the same roof as its sister factory GPS PLAS, in Long Hau Extended Industrial Park, Tay Ninh, with 200 tons per month of production capacity.

What makes a reliable modified PVOH partner

• Own material technology. AquaFlex is PVA PRO's own modified PVOH, so grades can be adjusted to your process instead of being bought in from a third party.
• Independent lab tests. ARCHA S.r.l. (Pisa, Italy) tested AquaFlex film under ISO and ASTM standards: passed ISO 14852 in 32 days in fresh water and ASTM D6691 in 43 days in natural seawater. These are lab test reports, valid references that most competitors on this material technology do not reach.
• Stable stock. Retained samples have stayed stable for more than five years in normal storage conditions, so you can order to a sensible stock level.
• Accessible volumes. A 500 kg minimum order lets you start with a trial run, and 200 tons per month of capacity lets you scale.
• Several forms from one source. Resin, liquid coatings, film, finished bags and AquaFlex paper.

Proof points from Vietnam

Behind the positioning are three firsts: PVA PRO is Vietnam's first modified PVA (PVOH) manufacturer, the first in Vietnam to produce PVOH film and packaging, and its AquaFlex is Vietnam's first modified PVOH resin. PVA PRO has developed its PVOH technology since 2022.

Recognition includes TECHFEST Finalist 2021-2023, i-star 2023, the Ho Chi Minh City Innovation Award 2025 and Vietnam Top Brand 2025. See the factory and expertise page.

How to qualify PVA PRO as a supplier

• Send your application, size, thickness and water temperature.
• Receive the matching grade data sheet and the lab test reports.
• Run a sample on your own line before you quote volume.
• Visit the factory, where retained samples can be seen.

The full checklist, with MOQ, shelf life and samples, is in How to source PVOH film. The technical reference is the AquaFlex film page.

What international buyers usually ask first

• Can you supply my volume? Capacity is 200 tons per month, with a 500 kg minimum order, so a brand can start with one product line and scale.
• Who makes the material? PVA PRO formulates the modified PVOH resin and converts it into film, bags and coatings in its own factory in Long Hau Extended Industrial Park, Tay Ninh.
• What proof do you have? Independent ARCHA lab tests: passed ISO 14852 in 32 days and ASTM D6691 in 43 days, plus SGS and Eurofins food contact reports by grade.
• How long does it keep? Retained samples have stayed stable for more than five years in normal storage conditions.
• Can I see it? Yes. We send samples and data sheets, and buyers are welcome to visit the factory.

Being part of TURN GREEN, alongside GPS PLAS, also means one team can compare water-soluble PVOH with compostable options for the same brief, so the recommendation follows the use case rather than a single product.

The market in numbers

Two lessons for buyers. Low-impact materials are still a tiny share of all plastics, so specialised suppliers are few. And capacity is not the same as output: European Bioplastics reports utilisation ranging from 28% to full capacity depending on the polymer (European Bioplastics market data). When you qualify a source, ask what is actually produced each month, not only what is installed.

Single source, from resin to finished bag

For AquaFlex paper, an established converter in the EU also produces under technology transfer, which gives European packers a second production point for that product. Quality can be checked in person: the factory keeps retained samples from its first production runs, and buyers who visit can see how film made years ago has kept its properties.

Documents you can request

• ARCHA S.r.l. lab test reports: ISO 14852 in fresh water (Nov 20, 2023); ASTM D6691 in natural seawater with OECD 202, report 22410332 (Dec 17, 2024); ISO 14855-1 and the EN 13432 checklist, report 22311632 (Feb 29, 2024).
• SGS: REACH test on an AquaFlex PVA bag; food contact test on AquaFlex B-CWS film.
• Eurofins: EU food contact tests on L-BAR and L-OPV coatings on cardboard (2024).
• PVA PRO: PFAS-free declaration based on a third-party lab in Italy; data sheet per grade; MSDS and COA on request.

When another material fits better

PVOH is the wrong choice if your product has to touch water in normal use. PVA PRO is a TURN GREEN company, and its sister factory GPS PLAS makes CompoFlex compostable, BioFlex biodegradable and ReFlex recycled materials, so we can compare options on the same brief. Read PVOH vs PLA vs PBAT.
