High-integrity medical disposables, high-performance PVC compounds, and precision structural barrier films engineered to international standards.
Pioneering Global Polymer and Packaging Technologies Since 1996
Founded in 1996, Jiangsu Dahai Plastics Co., Ltd. has established itself as an elite, high-capacity pioneer in the manufacture of engineered PVC films, advanced polymer compounds, and specialized printing technologies. As a privately-held enterprise dedicated to rigorous chemical engineering, our products range from ultra-high-clarity films and flexible medical-grade packaging materials to structural particles and eco-conscious sheets.
Spanning a world-class production area of over 120,000 square meters, Dahai Plastics operates more than 20 advanced, environmentally compliant calender and extrusion lines. With a workforce exceeding 450 professionals—including a dedicated 30% technical and management advisory council—our annual output exceeds 100,000 tons. Our manufacturing precision, driven by intelligent Industry 4.0 automation, fuels domestic leadership and secures substantial market shares across South America, Southeast Asia, Africa, and European industrial hubs.
Our commitment is simple: to supply the global supply chain with highly specialized, compliant, and cost-effective polymer materials that advance human health, product safety, and sustainable industrial growth.
Driving mechanical precision, structural longevity, and bio-based plastics engineering to meet future packaging architectures.
Developing molecularly stable, non-migratory plasticizers (e.g., DOTP, DINCH) for sensitive applications. Essential for medical-grade urine bags and IV formulations where toxicological safety cannot be compromised.
Engineering 5-layer and 7-layer functional barrier structures. This integrates high-oxygen, high-moisture barriers to prolong pharmaceutical and shelf-life variables while minimizing film gauge thickness.
Accelerating R&D in compostable PEVA, biodegradable plasticizers, and high-efficiency post-consumer recycled (PCR) plastics integration to satisfy rigorous carbon-neutral protocols without sacrificing tear-strength or weldability.
Our collaborative research with China's leading material sciences universities focuses on the macromolecular structure of vinyl compounds. By manipulating molecular weight distribution and micro-crystallinity during the calender processing stage, we produce PVC and PEVA sheets with optimal tensile profiles, exceptional optical transparency, and low-temperature durability. For instance, our proprietary raw material compounds (such as our 60-70 A PVC pellets) are custom-engineered to withstand cyclic stresses, making them the standard choice for complex mechanical components like footwear outsoles and high-flex containment solutions.
Tailored engineering specifications that optimize application efficiency across four core global industry segments.
Sterilizable, puncture-resistant medical plastics designed for enteral feeding bags, collection lines, and urine drainage vessels. Engineered to withstand high-pressure steam and gamma sterilization processes.
Heavy-duty, weather-resistant plastic films, high-density SPC flooring wear layers, and decorative laminated glass films (including 1.14mm Super Clear EVA films) designed to resist UV, water, and mechanical abrasion.
Non-toxic, highly pliable, and brilliantly colored PVC films. Perfect for high-stress inflatables, protective raingear, and domestic goods that require strict EN-71 safety and aesthetic compliance.
Ready-to-use PVC and PEVA pellets optimized for high-speed injection molding and blow-molding equipment. Designed for consistent viscosity, melt flow index, and color dispersal parameters.
Our specialized polymer materials are engineered for maximum performance across diverse global sectors.
Usually used for daily necessities and custom flexible packaging.
Usually optimized for heavy-duty industrial and construction purposes.
Usually utilized in strict non-toxic safety toy manufacturing.
Specially formulated for biological contact and clinical sanitation.
Unifying High-Volume Manufacturing with Dynamic Quality Assurance
Operating from our expansive 120,000 sqm central hub in Jiangsu, Dahai Plastics represents the pinnacle of Chinese high-tech manufacturing. With total assets valued at 140 million dollars and a registered capital pool of 40 million dollars, we run 20 advanced, environmentally conscious production lines. Our manufacturing ecosystem integrates raw compound formulation, high-precision film blowing, multi-color rotogravure printing, and automated cutting in a single continuous process. This vertical integration minimizes transport delays, preserves batch consistency, and guarantees that our annual production capacity of 150,000 tons is delivered efficiently to global distributors.
Our logistics network is optimized for swift dispatch. Located near key deep-water ports, we guarantee fast transit to international lanes, reducing transit times to key markets in North America, South America, Europe, and Southeast Asia. Additionally, our intelligent inventory systems monitor raw chemical feedstock and finished roll stocks, safeguarding our global supply partners against volatile market swings and supply chain interruptions.
Our commitment to sustainable development, safety engineering, and mutual commercial triumph.
Make green materials, create a good and healthy life!
To become the domestic polymer material application industry leader, to build a world-class brand!
Independent innovation intelligent future! Team style: people-oriented safety first!
Integrity, pragmatic, efficient, win-win!
Scientific validation at every phase of polymer formulation.
Our quality control infrastructure centers on our testing laboratories accredited by the China National Commission for Conformity Assessment (CNAS). These facilities feature advanced physical and chemical testing-analysis systems, including universal tensile testing machines, Agilent Gas Chromatography (GC) mass analyzers, precision gloss meters, and environmental cold-tolerance testing systems.
By measuring trace elements, monitoring plasticizer migration, and verifying mechanical tolerances down to the micron level, we guarantee batch consistency. Our technical engineers work alongside university research teams to translate new polymer formulations into stable, high-volume production. This commitment to compliance ensures our films reliably meet the standards of major global markets.
EN-71 (European Toy Safety Standards), ASTM-F-963 (Standard Consumer Safety Specification for Toy Safety), Model Toxics in Packaging Legislation (CONEG), and RoHS/REACH environmental directives.







Addressing the critical risk mitigation, raw material stability, and carbon reduction mandates of modern procurement teams.
For modern procurement officers, sourcing polymer films is no longer just about per-ton pricing. It requires managing geopolitical risks, shipping congestion, compliance changes, and quality variation. Dahai Plastics addresses these challenges by offering stable, integrated production. Controlling the manufacturing process from compound preparation to final slitting insulates our clients from pricing fluctuations in intermediate markets.
Regulatory frameworks like the EU's REACH regulation and the US's state-level CONEG toxics packaging laws continue to lower the limit for heavy metals and migratory phthalates. Dahai Plastics stays ahead of these changes by investing in alternative plasticizers, such as DOTP and specialized PEVA materials. Our chemistry department ensures that our translucent soft PVC granules and super-clear film rolls remain flexible and strong, while meeting the strict safety guidelines required for consumer products and medical devices.
Improperly formulated film rolls are prone to blocking, where adjacent layers fuse together during transport through high-heat, high-humidity shipping lanes. We address this by applying specialized anti-blocking agents and precise corona surface treatments. This ensures our rolls unwind smoothly, even after long ocean transits, minimizing downtime for your high-speed printing and thermoforming lines.
