Sengong is a next-gen PVA materials company founded on the vision to make eco-friendly materials as accessible as possible to the world. We believe sustainable products should be affordable, inclusive, and scalable — not expensive or exclusive.
Explore Our MaterialsWhen we saw how our oceans were clogging up with waste that shouldn’t be there — and nobody was responsible for it — we knew a new approach was needed. Sengong’s name combines ‘Sen’ (forest) and ‘Gong’ (industry), meaning ‘a material industry designed to work with the forest’.
We’re not here to start a material revolution. Instead, we focus on practical, user-driven solutions. Consumers value convenience and may not recycle consistently. That’s why we’ve evolved biodegradable PVA into an affordable, accessible, and scalable solution.
PVA isn’t new — it’s been around since 1912. But it was expensive. We’ve made it cost-effective, recyclable, reusable, and fully biodegradable without relying on food-based resources like corn.
Over 130 unique formulas engineered for diverse applications — from consumer goods to industrial packaging and environmental restoration.
High-strength water-soluble film for industrial packaging and detergent pods.
Soil-stabilizing film for agriculture, reforestation, and desertification control.
Single-use packaging film for detergents, agrochemicals, and cosmetics.
Certified eco-film with full EIA compliance and traceable sourcing.
Flexible, multi-layer PVA film for complex packaging needs.
Designed to degrade rapidly in marine environments without microplastics.
Recyclable PVA film for closed-loop industrial systems.
Heat-resistant PVA film for high-temperature applications.
PVA is the only polymer that bacteria can use as a carbon source, degrading by 75% in 46 days without microplastics.
Our in-house engineered lines produce films up to 4x faster than competitors, with 20,000-ton annual capacity.
Raw materials sourced locally in China reduce shipping dependency and lower costs by up to 75%.
Unlike corn-based bioplastics, our PVA doesn’t compete with food supply chains.
We recycle waste steam from a nearby power plant, achieving 80% energy reuse and 50% lower energy costs.
Backed by over 25 patents in material science, manufacturing, and application design.
We believe sustainability must be affordable, accessible, and measurable. Our green manufacturing process ensures real environmental impact without premium pricing.
Yes. PVA is the only polymer that bacteria can use as a carbon source. It degrades by 75% in 46 days in standard conditions.
No. When PVA dissolves and degrades, it breaks down into carbon dioxide and water — not microplastics.
Our manufacturing plant is located in Linyi, Shandong Province, China.
Yes. PVA can be dissolved and reused in multiple cycles. At end-of-life, it can be applied in agricultural soil enhancement.
Yes. We offer over 130 unique formulas and can engineer custom solutions for specific solubility, strength, and temperature needs.
Whether you have questions about our PVA films, need technical support, or want to explore partnership opportunities, we're here to help.
