Explore our primary catalog of high-performance PVC films, sheets, and packaging rolls engineered for demanding medical, structural, and consumer applications.
Flexible Polyvinyl Chloride (PVC) compounds serve as the foundational backbone for critical global supply chains. By dynamically blending PVC resin with carefully curated plasticizers, stabilizers, modifiers, and lubricants, manufacturers synthesize materials that balance structural flexibility, chemical resistance, and long-term durability.
In the contemporary B2B landscape, the demand for flexible PVC compounds has shifted from basic material properties toward highly engineered, application-specific formulations. Industries demand compliance with stringent regulatory frameworks, including European Union REACH Annex XVII, RoHS, FDA, USP Class VI, and environmental directives prohibiting phthalate-based plasticizers (such as DEHP/DOP) in sensitive environments.
As a leading pioneer in this domain, Jiangsu Dahai Plastics Co., Ltd. spearheads the engineering of advanced vinyl formulations. We specialize in producing compounding granules and calendered films that address challenges across medical fluid containment, rigid thermoforming, high-wear structural barriers, and cold-resistant outdoor consumer products.
Founded in 1996, Jiangsu Dahai Plastics Co., Ltd. is a premier private enterprise dedicated to the technical formulation, production, and processing of high-grade PVC films, printing films, and polymer granules.
Dahai Plastics operates a state-of-the-art manufacturing campus spanning over 120,000 square meters. With a continuous investment of resources in cutting-edge machinery, the facility hosts more than 20 advanced production lines, including imported environmental protection calender lines and high-torque compounding extruders.
Our dedicated workforce of over 450 professionals includes 30% technical management specialists who supervise a rigorous, end-to-end quality assurance program. Annually, Dahai produces in excess of 100,000 tons of premium PVC films and compounds, driving annual sales past 1 billion CNY ($180 million USD), with global export operations extending across South America, Southeast Asia, Africa, and beyond.
We mainly produce an extensive portfolio of vinyl products tailored to customer specifications: super transparent film, ordinary transparent film, toy film, bath film, raincoat film, electrical tape film, cold film, non-stick film, decorative film, PEVA film, particles, tablecloths, shower curtains, and medical-grade urine bags.
At Jiangsu Dahai, we operate under a unified framework of sustainable progress, technological integrity, and human-centric engineering.
“Make green materials, create a good and healthy life!” We formulate materials with long-term human safety and environmental impact in mind.
“To become the domestic polymer material application industry leader, to build a world-class brand!” Through advanced testing and custom engineering, we set global standards.
“Independent innovation, intelligent future! Team style: people-oriented, safety first!” Empowering workers while investing heavily in smart compounding automation.
Every industry presents unique mechanical, chemical, and physical constraints. Dahai Plastics engineers PVC compounds that target specific performance profiles, ensuring seamless processing via extrusion, calendering, and injection molding.

When selecting a flexible PVC compounding manufacturer, B2B buyers must specify detailed operational tolerances. Our laboratories calibrate several physical and chemical properties during production:
Operating out of our centralized production hub in Jiangsu, Dahai Plastics utilizes highly automated compounding silos. This guarantees homogeneity across large production campaigns. Our tracking records show a consistent throughput capacity that easily services massive annual supply contracts. Underpinning this volume is our strategic proximity to major shipping ports, providing fast logistics to international distributors, local compounding plants, and downstream converters.
To assure consistency across batches, Jiangsu Dahai maintains an advanced in-house testing laboratory accredited by the China National Commission for Conformity Assessment (CNAS). This facility serves as our frontline defense, verifying structural, chemical, and physical parameters before dispatch.
Our analytical suites host cutting-edge instruments, including:
Additionally, we maintain long-term partnerships with third-party verification agencies (SGS, TUV, Intertek). All products can be custom-tested to satisfy the requirements of EN-71, ASTM-F-963, Model Toxics in Packaging Legislation (CONEG), RoHS, and REACH directives.
Flexible PVC properties must align with local environmental parameters and processing realities. Here is how Dahai adapts formulations for distinct regional applications:
Hot & Humid Environments: Formulations are modified with fungicides and heat-stabilizers to prevent microbial growth (molds) and thermal yellowing in high relative humidity. Suitable for outdoor inflatables and tropical civil construction films.
Cold-Resistance (Antifreeze): Formulations for rainwear, protective agricultural sheeting, and industrial strip doors include plasticizers that retain flexibility at sub-zero temperatures, preventing cracking and structural brittleness.
Urine and Enteral Feeding Bag Assembly: High-purity, low-bleed PVC film rolls designed for rapid high-frequency (RF) welding. Optimized to prevent material deformation during gas-phase, liquid chemical, or radiation sterilization.
The global PVC compounding industry is transitioning toward eco-compatible materials. As part of our commitment to sustainable development, Jiangsu Dahai has established a dedicated R&D roadmap to integrate advanced bio-based materials and smart production technologies.
We are actively shifting the production of consumer-facing films toward non-phthalate plasticizers (DOTP, DINCH, and Citrates). This is crucial for medical devices and toy manufacturers who face tightening global regulations.
Through our close collaboration with university research teams, we are testing compound options derived from epoxidized vegetable oils (ESBO) and agricultural byproducts. This reduces the carbon footprint of PVC manufacturing while maintaining identical tensile performance.
Dahai is building digital dosing and automated mixing lines. These systems reduce compounding errors and support the integration of post-industrial and post-consumer recycled (PCR) PVC, aligning with the principles of a circular economy.
