Explore our flagship precision-engineered film rolls, medical-grade compounds, and high-clarity rigid sheets manufactured under strict CNAS and international quality standards.
Pioneering High-Performance Polymer Engineering, Precision Calendering Technology, and Global Supply Integrity Since 1996
Founded in 1996, Jiangsu Dahai Plastics Co., Ltd. stands as an authoritative force in the synthetic polymer industry, operating as a top-tier private technology enterprise dedicated to the research, development, and high-capacity manufacturing of flexible, semi-rigid, and rigid PVC films, functional printing PVC sheets, and eco-friendly PEVA materials.
Spanning an expansive manufacturing footprint exceeding 120,000 square meters, Dahai Plastics integrates over 20 state-of-the-art automated calendering and extrusion lines. Backed by a dedicated workforce of 450+ industry professionals—where technical management and polymer engineers comprise more than 30% of total personnel—our organization maintains an annual output capacity exceeding 100,000 metric tons, driving annual sales past 1 Billion RMB.
Analyzing the macro-economic and engineering advantages that position Chinese polymer factories at the center of global B2B procurement strategies.
China's specialized chemical production zones provide instant access to raw resin monomers, non-phthalate plasticizers, heat stabilizers, and bio-based additives. This upstream integration drastically reduces raw material transit friction, mitigates price volatility, and guarantees continuous batch consistency for large-scale enterprise buyers.
Modern Chinese film plants house multi-roll calendering equipment capable of maintaining sub-micron thickness tolerances (e.g., ±0.005mm across a 2000mm width). High-speed automated gauge control (AGC) ensures seamless optical clarity, uniform tensility, and zero pinhole defects across high-volume production runs.
Through economies of scale, automated web inspection, and thermal energy recovery systems, Chinese manufacturers deliver unmatched unit-cost efficiencies. Global procurement teams benefit from reduced landed costs while maintaining strict adherence to Western regulatory standards like REACH and RoHS.
How next-generation material science is revolutionizing flexible packaging, medical fluid containment, and industrial laminates.
Regulatory pushback against traditional DEHP/DOP plasticizers has accelerated the adoption of DOTP, DINCH, and citrate-based bio-plasticizers. Next-gen PVC soft films provide full biocompatibility for medical urine drainage bags and enteral feeding systems without leaching toxic compounds.
Modern pharmaceutical blister packaging demands extreme moisture and oxygen barrier properties. Custom rigid PVC films co-extruded with PVDC or laminated with PE/EVOH shield sensitive capsules and tablets from ambient degradation, extending shelf-life in humid tropical climates.
The architectural glass sector is shifting toward 1.14mm super-clear EVA laminated films. Offering crosslinking rates exceeding 85%, these films ensure superior UV blocking, moisture resistance, and acoustic dampening for high-rise facades and decorative safety glass installations.
Tailored polymer formulations solving complex industrial, healthcare, and architectural challenges.
Medical manufacturing requires ultra-pure, non-toxic polymer films. Our soft translucent PVC film rolls and finished disposable 2000ml urine drainage bags and ENFit enteral feeding bags undergo rigorous ethylene oxide (EO) sterilization validation, ensuring high RF welding strength, drop impact resistance, and leak-proof performance in hospital wards worldwide.
For commercial building applications, durability and UV stability are essential. Our highly transparent SPC wear layer films offer extreme micro-scratch resistance, preserving printed wood/stone grains under heavy foot traffic. Concurrently, 1.14mm EVA films provide structural integrity and acoustic insulation for decorative safety glass.
From high-clarity clear tablecloths to heavy-duty recreational inflatables, our customized color PVC films deliver high tensile strength, cold-crack resistance (-15°C to -30°C), and resistance to weather degradation. Formulations comply with strict EN-71 and ASTM-F-963 toy safety regulations.
Our raw material compounding department produces specialized translucent soft PVC pellets (60-70 Shore A) for injection-molded shoe soles and waterproof boots. These masterbatch granules ensure excellent fluidity during molding, high abrasion resistance, and consistent surface finish.
Rigorous physical, chemical, and analytical testing protocol backing every metric ton leaving our production line.
At Jiangsu Dahai Plastics Co., Ltd., quality assurance is deeply embedded in our engineering culture. We possess dedicated laboratories accredited by the China National Accreditation Service for Conformity Assessment (CNAS). Our analytical facility is equipped with state-of-the-art testing instrumentation including Universal Electronic Tensile Testers, Agilent Gas Chromatography (GC) Analyzers for residual monomer and plasticizer detection, Precision Optical Gloss Meters, and Automated Low-Temperature Cold-Tolerance Testers.
Even the slightest chemical variance or physical deviation is detected before shipment, guaranteeing that our products strictly comply with international market mandates: EN-71 (European Toy Safety Standard), ASTM-F-963, Model Toxics in Packaging Legislation (CONEG), and EU RoHS Directives.
Financial stability, rapid industrial scaling, and strategic relationships across over 400 domestic cities and 10+ international regions.
Total group registered capital reaches $40 Million USD, with total consolidated asset valuation exceeding $140 Million USD. This financial robustness ensures long-term contract reliability and supply chain stability for multi-national B2B clients.
Operating 20 imported environmentally protected calendering and extrusion lines, our manufacturing footprint achieves up to 150,000 tons of total annual polymer production capacity across specialized film lines.
In line with market evolution, Dahai is constructing an advanced intelligent manufacturing facility focused exclusively on specialized medical polymers and ultra-clean flexible packaging films.
