Ningbo Huanxin Industry & Trade Co., Ltd. is a modern industrial and trading enterprise dedicated to the R&D, manufacturing, and global sales of EVA films and PVB films (Polyvinyl Butyral films). Deeply rooted in core product areas such as EVA encapsulation films and PVB interlayer films, the company operates under the philosophy of "Quality as the Foundation, Global Empowerment." It provides customers worldwide with highly secure, highly adaptable, and cost-effective film material solutions, covering diverse application scenarios including architecture, automotive, photovoltaics, and home decoration.

Situated in Ningbo—a major port and industrial hub in China—the company leverages the city's unique advantages in maritime logistics to establish a highly efficient global supply chain system. Its products are exported to dozens of countries and regions across Europe, the Americas, Southeast Asia, and the Middle East. Serving a wide range of sectors—including architectural laminated glass processing, automotive glass manufacturing, photovoltaic module encapsulation, and interior decoration—the company has become a core supplier of film materials for numerous downstream enterprises.

On the production front, Huanxin Industry & Trade is equipped with standardized clean workshops and advanced film processing machinery. The company strictly adheres to ISO quality management system standards, ensuring meticulous control over the entire process—from raw material selection and formula R&D to finished product manufacturing. The EVA film, based on an Ethylene-Vinyl Acetate (EVA) copolymer substrate, features formulas precisely calibrated according to Vinyl Acetate (VA) content. It boasts high light transmittance, low water absorption, excellent adhesion, and ease of processing. Compatible with lamination furnace processing techniques, it is ideally suited for applications such as interior decorative glass and photovoltaic module encapsulation, offering outstanding cost-effectiveness. The PVB film is manufactured using high-quality PVB resin combined with plasticizers; its stable molecular structure provides exceptional adhesion to glass, as well as superior weather resistance and impact strength. Compatible with autoclave processing techniques, it is designed for high-end safety applications such as architectural curtain walls and automotive windshields. It effectively blocks ultraviolet rays while offering excellent sound and thermal insulation properties; furthermore, in the event of breakage, it firmly retains glass fragments, thereby significantly reducing the risk of injury. Both product lines strictly exclude the use of recycled materials, ensuring stable and reliable quality, and are tailored to meet the specific core requirements of their respective application scenarios. The company boasts a professional R&D team dedicated to the in-depth optimization of EVA and PVB film formulations and process innovation. Tailoring to the unique requirements of overseas clients, we provide customized products featuring specific thicknesses, dimensions, colors, and functionalities—such as UV resistance, high reflectivity, and enhanced sound insulation. We offer a comprehensive suite of end-to-end services, encompassing expert pre-sales consultation, formulation design, logistics and delivery, and after-sales support. We closely monitor customer feedback throughout the entire process, ensuring the timely resolution of any issues encountered during product application. Leveraging our consistent product quality, highly competitive cost advantages, and global trade service capabilities, Huanxin Industry & Trade has established long-term, stable partnerships with numerous overseas glass processing plants, automotive component manufacturers, and photovoltaic module producers, thereby earning widespread market recognition.

Looking to the future, Ningbo Huanxin Industry & Trade will continue to deepen its expertise in the core fields of EVA and PVB films, driving product upgrades through technological innovation. We remain focused on the R&D and production of eco-friendly, high-efficiency, and high-performance film materials. Upholding our principles of integrity and mutual benefit, we will continuously optimize our global supply chain system, striving to become a trusted, specialized supplier of EVA and PVB films for clients worldwide, and contributing to enhanced safety and quality standards across the global construction, automotive, and photovoltaic sectors.
