In the contemporary industrial and environmental landscape, the demand for high-integrity containment systems has reached an all-time high. As a China leading PVC liners supplier, we recognize that geomembranes and PVC liners are no longer just construction materials—they are critical infrastructure components that protect our groundwater, stabilize our soil, and manage our planet's most precious resources.
From the arid mining regions of Chile to the intensive aquaculture farms in Southeast Asia, the global market for PVC and polyethylene liners is expanding at a CAGR of over 5%. This growth is driven by stringent environmental regulations, the rise of "Sponge City" urban planning, and the urgent need for sustainable waste management solutions. Today, industrial PVC liners are utilized in massive civil engineering projects, including tailing dams, hazardous waste landfills, and complex irrigation networks.

Relying on a long-term and stable raw material supply system and strict product formulas, we can customize various material products such as HDPE, LDPE, EVA, and ECB according to specific project requirements.
The company has passed the ISO9001, ISO14001 and OHSAS18001 certifications. Our professional technical personnel use advanced equipment and instruments to ensure every roll meets international standards.
With 3 chief chemical process engineers and 5 mechanical engineers, we don't just sell products; we provide engineered solutions tailored to soil conditions, UV exposure, and chemical resistance needs.
Our PVC liners and geomembranes are engineered for the world's toughest environments.
Our high-density liners act as an impermeable barrier, preventing toxic leachate from contaminating groundwater. Our rough geomembranes provide the necessary friction to stabilize steep landfill slopes.
Environmental friendliness and non-toxicity are paramount in fish and shrimp farming. Our EVA and LDPE liners ensure a clean, controlled environment that boosts yields and prevents water loss.
Chemical plant slag yards and tailings dams require liners with extreme chemical resistance. Our custom ECB and HDPE solutions are designed to withstand aggressive acidic and alkaline environments.
From artificial lakes to siphonic drainage systems, our products support the infrastructure of sustainable cities, managing storm water and preventing soil erosion in canals and reservoirs.
The industry is shifting towards "Smart Geosynthetics"—materials that integrate sensing technology to monitor leaks in real-time. While we maintain leading production lines for traditional smooth and double-color geomembranes, Taian Changhong is continuously investing in R&D to enhance the anti-aging properties and UV resistance of our films.
Sustainability is another major trend. Global procurement teams are now prioritizing suppliers who offer long-service-life materials, reducing the need for frequent replacements and minimizing the environmental footprint of construction projects. Our commitment to using high-grade virgin resins ensures that our products serve the infrastructure for decades, not just years.
Taian Changhong Engineering Materials Co., Ltd. specializes in the production of smooth geomembrane, rough geomembrane, double color geomembrane, geotextiles (polyester short fiber non-woven fabric, polyester long fiber non-woven fabric, polypropylene short fiber non-woven fabric, hot-rolled non-woven fabric), drainage board, drainage net, geogrid, geocell, flexible permeable pipe, plastic blind drain and other environmentally friendly geosynthetic materials.
Our company's products feature anti-aging, long service life, environmental friendliness, and non-toxicity. Our strong technical strength ensures the stability and forward-looking nature of the products. With over 60 employees, including a elite team of chemical and mechanical engineers, we maintain leading geosynthetic material production lines and testing equipment.
Changhong is always committed to making friends with customers, getting close to them with sincerity, satisfying them with actions, and achieving win-win results. Based on excellent products and services, we provide customers with stable and advanced solutions and establish long-term friendly cooperative partnerships.
