Explore our industrial-grade PVC and polymer films optimized for infrastructure, laminated safety glass, waterproofing, and specialized protection.
Decoding the physical, chemical, and structural performance criteria of construction-grade plastic films and sheets.
In the contemporary global construction landscape, the reliance on high-performance polymer materials has reached unprecedented levels. Modern civil engineering demands materials that offer structural integrity, environmental resilience, aesthetic flexibility, and long-term cost efficiency. China plastic for building material manufacturers have established themselves at the intersection of chemical innovation and scalable manufacturing, producing polymers that meet the rigorous criteria of European, American, and international construction standards.
Polyvinyl Chloride (PVC) and Ethylene-Vinyl Acetate (EVA) represent two of the most critical structural and auxiliary materials in construction. PVC, with its highly polar carbon-chlorine bonds, exhibits exceptional chemical resistance, flame-retardant properties, and inherent stiffness, which can be modified using plasticizers to produce anything from rigid thermoforming sheet rolls to highly flexible, transparent protective soft films. On the other hand, EVA films serve as crucial structural interlayers for architectural laminated safety glass. These interlayers provide superior cross-linking density, sound insulation, UV block capabilities, and mechanical energy absorption, reducing structural risk in modern glass curtain walls and glass roofs.
Understanding these material profiles is fundamental for developers, engineers, and international sourcing directors. The correct matching of polymer formulations with specific architectural microclimates prevents premature material degradation, prevents plasticizer migration, and guarantees that interior and exterior elements preserve their integrity under mechanical loading, solar radiation, and fluctuating temperatures.
Pioneering polymer extrusion and film casting solutions since 1996.
Founded in 1996, Jiangsu Dahai Plastics Co., Ltd. is a prominent, private technology-driven enterprise specializing in the design, engineering, and mass-production of high-quality PVC films, structural membranes, and compound granules. Our manufacturing expertise stretches across a broad product matrix: from super transparent films, ordinary clear films, toy films, bath and shower curtain films, to specialized building materials like rigid thermoformed PVC sheets, SPC wear layers, decorative laminated glass EVA films, medical-grade urine bags, and enteral feeding containers.
Occupying an expansive footprint of over 120,000 square meters, our facilities represent the state-of-the-art in lean manufacturing. DAHAI operates more than 20 advanced production lines, employing over 450 skilled professionals, with over 30% of the workforce dedicated to technical management, scientific research, and quality assurance. With an annual production volume exceeding 100,000 tons and annual sales surpassing 1 billion RMB, we continuous adapt and introduce advanced production technologies, supplying not only the domestic market but exporting directly to South America, Southeast Asia, Africa, Europe, and the Middle East.
A look at our capital capabilities, investment in technology, and scientific verification methods.
The total registered capital of projects operating under the Dahai Group umbrella is $40 million USD, with total operational assets reaching $140 million USD. Our facilities include 20 imported environmental protection production lines that yield an annual production capacity of 150,000 tons of specialized materials. In 2018, the group achieved record sales of $180 million USD, of which direct exports accounted for $10 million USD. Today, our products are distributed across 400 cities in 12 domestic provinces, while exports span across more than 10 global destinations. In light of modern green development trends, we are currently planning and constructing advanced intelligent manufacturing facilities focused on new medical-grade materials and eco-friendly building films.
At the center of our quality commitment is our state-of-the-art analytical testing laboratory, accredited by the China National Accreditation Service for Conformity Assessment (CNAS). This facility houses sophisticated diagnostic equipment:

How we leverage advanced industrial engineering to guarantee consistent quality and absolute cost control.
Jiangsu Dahai Plastics operates at the vanguard of the Industry 4.0 revolution. In the chemical and polymer processing sector, automation, real-time feedback loops, and precision extrusion control are vital to prevent material defects. Our 20+ production lines feature computerized thickness measurement sensors, automatic dosing systems for plasticizer-resin ratios, and closed-loop temperature control units. This ensures that a 0.15mm soft PVC roll or a 1.14mm architectural EVA film retains perfect dimensional thickness across kilometers of production.
By producing our own intermediate compounds, including specialized polymer pellets and granules, we secure our supply chain from the price volatility of raw petrochemical materials. This vertical integration allows us to keep our pricing highly competitive while maintaining strict control over compound purity. In addition, our manufacturing setup is designed for flexible product switches. We can rapidly re-program calender lines to shift from standard clear PVC sheets to medical-grade films, protecting our operational efficiency and satisfying varying international procurement schedules.
Meeting international environmental safety laws and ensuring seamless regional shipping logistics.
Sourcing building plastics and specialized films from China requires strict compliance with destination country regulations. Sourcing agents, project developers, and building material suppliers must verify that every square meter of film complies with relevant chemical and heavy-metal restrictions. All DAHAI products can be customized to pass the target thresholds of:
To support global supply chains, we provide comprehensive customs clearance documentation, technical product sheets, and direct technical consultations. Our logistics hub near the East China ports guarantees rapid port transfer times, reducing cargo delay risks. We work closely with distribution hubs across South America, Southeast Asia, and Africa, allowing us to customize shipping schedules, optimize roll packaging to minimize volume weight, and deliver cost-effective logistics support.
Our commitment to internationally recognized manufacturing and quality control standards.
We import advanced testing equipment, such as universal testing machines, Agilent GC analyzers, gloss meters, and cold-tolerance testers. Working alongside third-party laboratories, we ensure that every batch meets the requirements of EN-71, ASTM-F-963, CONEG, and RoHS.
