Discover our comprehensive range of high-performance plastic films, granules, and customized industrial solutions engineered for global applications.







Rooted in polymer manufacturing since 1996, driving industrial innovation worldwide.
A deep dive into supply chain intelligence, manufacturing prowess in China, and macro industry solutions.
In the global supply chain matrix, Chinese manufacturing infrastructure has established unrivaled dominance in polymer processing and plastic construction film fabrication. Leveraging economies of scale, highly integrated regional industrial clusters, and aggressive investments in intelligent manufacturing, Chinese factories deliver exceptional cost efficiencies without compromising structural integrity or chemical stability. Facilities equipped with advanced automated calender lines and strict environmental compliance protocols ensure consistent material performance for global construction and infrastructure projects.
The global construction film market is transitioning rapidly towards sustainability, high durability, and smart material integration. Modern polymer science emphasizes eco-friendly plasticizers, enhanced UV stabilization, and multi-layer co-extrusion techniques that improve tensile strength and puncture resistance. Furthermore, the incorporation of CNAS-accredited laboratories directly on factory floors allows real-time spectroscopic and physical testing, ensuring every batch of construction film meets international standards such as ASTM and EN-71.
Plastic construction films serve critical roles across diverse geographical and climatic environments—ranging from vapor barriers in subterranean foundations and moisture protection in roofing to temporary enclosures and concrete curing blankets. Global enterprise buyers demand stringent quality certifications, custom thickness tolerances (ranging from 0.15mm to rigid heavy-duty gauges), and reliable logistics support. Partnering with certified manufacturers guarantees traceability, customized formulation, and long-term project reliability.
Committed to rigorous testing standards and a visionary mission for sustainable polymer development.
We possess laboratories accredited by China National Commission for Conformity Assessment (CNAS), which are equipped with many kinds of world advanced experimental equipment and physical and chemical testing-analysis instruments. In every experiment, in every test, even the slightest difference can be detected by our machines, which greatly guarantees the quality of our products.
DAHAI continues to invest resources, and we will work with university teams to develop products. Our technical department is constantly learning new technologies and combining them with our own situation, through which our ability to innovate is keeping improving.
