Explore our top-tier engineering solutions, certified for precision performance across demanding medical, construction, and consumer segments.
The global demand for industrial plastic films—predominantly formulation-driven Polyvinyl Chloride (PVC) and Ethylene-Vinyl Acetate (EVA) polymers—has undergone a critical shift from basic commodity provisioning to complex macromolecular engineering. Industrial, medical, and commercial infrastructure supply lines now demand materials that display enhanced thermal resistance, custom structural plasticization, non-toxic environmental profiles, and micro-tolerance barrier capabilities.
As multi-national regulatory frameworks tighten, particularly surrounding the application of polymer films in contact with therapeutics or packaging, the search intent of global procurement directors has evolved. Key priorities include validating chemical inertness, proving compliance with complex test parameters (such as the RoHS Directive and ASTM mechanical tests), and establishing supply pipelines with high-capacity partners who run automated fabrication lines.
Strict structural stability protocols and physical-chemical certifications (ISO, CNAS) are critical for liquid transport, enteral feeding, and fluid collection bags.
Global logistics networks require systematic conformity to EN-71, REACH, RoHS, and CONEG packaging legislation to bypass cross-border compliance bottlenecks.
Calendering and extrusion technologies allow manufacturers to tailor flexibility, surface gloss, UV stability, and flame-retardant properties.
A deep dive into our manufacturing infrastructure, advanced polymer engineering, and structural capacity metrics.
Established in 1996, Jiangsu Dahai Plastics Co., Ltd. has grown into an international industry leader in polymer film manufacturing. Our 120,000-square-meter facility houses advanced, eco-friendly calendering and extrusion lines. We convert raw vinyl resins and specialized polymers into complex flexible materials, outputting over 100,000 tons of high-performance film annually.
Our technology division focuses on advanced PVC and PEVA formulations. We produce ultra-clear, soft, and embossed films tailored for medical devices, technical laminates, electrical insulation, and durable packaging. By using high-efficiency calendering and automated gauge control systems, we maintain minimal thickness deviations across production runs, satisfying the strict requirements of overseas industrial supply chains.
How Dahai Plastics leverages integrated digital systems, automated quality control, and strategic location advantages.
The modern industrial film supply chain requires rapid iteration, strict chemical control, and high yield consistency. In response, Dahai Plastics has integrated Factory 4.0 technology into our production facility in Jiangsu. Centralized raw material silo controls ensure precise ingredient dosing, eliminating manual errors and preventing batch contamination. This level of control is crucial for complex formulations like pharmaceutical-grade PVC and food-safe PEVA.
Our calendering lines feature closed-loop optical and beta-gauge measurement sensors. These instruments monitor thickness variations in real time, automatically adjusting the roll gap. This system keeps dimensional tolerances within ±2%, far tighter than the industry standard. This precision prevents downstream issues like uneven tension during printing, lamination, and automated medical bag fabrication.
Dahai polymer solutions are engineered to meet the unique challenges of diverse global industries.
High-strength packaging film suitable for consumer goods, textiles, and heavy-duty storage applications.
Durable, moisture-barrier PVC components for SPC flooring, structural laminates, and insulation applications.
Non-toxic, safe PVC and PEVA films certified to meet international EN-71 and ASTM safety standards.
Medical-grade films engineered for urine drainage bags, enteral feeding bags, and protective barriers.
Quality assurance at Dahai Plastics relies on our modern testing facility, which is accredited by the China National Commission for Conformity Assessment (CNAS). This accreditation validates our adherence to international standards and testing precision.
Our laboratories are equipped with precision instruments, including universal electronic tensile testers, Agilent gas chromatographs for plasticizer migration testing, optical gloss meters, and environmental chamber systems for testing low-temperature resistance down to -30°C.
These validation protocols confirm that every batch of film matches our customers' specifications and complies with key regulatory standards, including EN-71 (parts 1, 2, and 3), ASTM-F-963, CONEG packaging directives, and the RoHS Directive. We also collaborate with academic research labs to develop next-generation polymer blends and halogen-free alternatives.

Get answers to technical questions about formulation, application, and compliance from our polymer engineering team.
We use an automated, closed-loop thickness sensor system that continuously scans the web width. When deviations are detected, the system automatically adjusts the roll position on the calender, keeping thickness variations within ±2%. This precision ensures uniform performance during heat sealing and lamination.
Our medical films, designed for fluid drainage and enteral nutrition packaging, are tested in our CNAS-accredited laboratory. They comply with ISO 10993 biocompatibility testing, USP Class VI requirements, and international regulations, including REACH and RoHS. This prevents plasticizer migration and chemical contamination.
Yes. We can modify our polymer formulations with specialized cold-resistant plasticizers, allowing the film to remain flexible down to -30°C without cracking. This formulation is frequently used in cold-chain logistics, agricultural protective covers, and outdoor equipment.
Standard production runs for custom-formulated PVC/PEVA rolls take 14 to 21 days, depending on formulation complexity and tooling requirements. With our annual capacity of 100,000 tons, we can manage large orders in parallel to maintain stable supply timelines for international clients.
During formulation design, we prepare initial test sheets and evaluate them in our CNAS laboratory. Once they meet the required mechanical and safety specifications, we can arrange for independent compliance certification with international testing bodies (SGS, TUV, or Intertek) prior to starting volume production.
