History and Development
WUJIANG POLIMIROIR is part of a French-origin industrial group whose roots in roll manufacturing date back to 1955, when Polimiroir was created in France. The parent group later expanded internationally and established a Chinese presence in Wujiang, near Shanghai, to serve regional customers in plastics and related industries more directly.
A trade-profile description indicates that the Chinese subsidiary was created in 2012 as the group’s strategic entry into the Asian market. By the mid-2020s, the company was presenting itself at Chinaplas as an established supplier to OEMs and engineering customers in the plastics film sector, highlighting both its roll-production capabilities and its coating technologies.
Recent company communications also indicate that the Wujiang operation has continued to evolve, with references to a planned new facility and a broader local industrial footprint in the Wujiang/Pingwang area. This suggests a continuing emphasis on capacity expansion and proximity to China’s plastics-processing base.

- Coating and laminating lines
The company is described as combining the know-how of the wider Polimiroir group with local manufacturing in China, which positions it as both a regional supplier and a technology transfer platform within the group’s international structure.
Products and Technologies
WUJIANG POLIMIROIR’s product portfolio centers on industrial rollers and specialized roll surfaces. Trade-fair materials identify examples such as chill rolls, casting rolls, and hard-coated rolls, reflecting the importance of thermal control, surface durability, and dimensional precision in polymer film processing.
Key technical capabilities
- HVOF LF spraying: a high-velocity oxygen fuel coating process used to apply dense, wear-resistant coatings.
- Atmospheric plasma spraying: a thermal-spray method suitable for engineered surface layers with tailored performance properties.
- Hard-coat and spray-coated roll surfaces: used to improve wear resistance and service life in demanding continuous-process environments.
- Large-format roll processing: capacity for very large components, including parts up to 2.1 m diameter and 12 m length.
The company’s technical positioning is especially relevant in plastics film lines, where surface uniformity, thermal stability, and resistance to abrasion or chemical exposure can directly affect product consistency and uptime. The parent group also notes broader surface-treatment options such as electrolytic chrome, nickel, and copper deposition within its industrial roll and coating portfolio, indicating a wider metallurgical service base around the Wujiang operation.
Applications and End Markets
The main end market for WUJIANG POLIMIROIR is the plastics film industry, particularly producers of oriented films and related converting lines. The company’s solutions are used in process stages where roller precision affects:
- Film thickness uniformity
- Surface finish
- Cooling and solidification behavior
- Web guidance and tension stability
- Line uptime and maintenance intervals
More specifically, its cited applications in BOPP and BOPET lines point to use in packaging films, industrial films, and other high-volume polymer sheet and film products. Its presence at Chinaplas also places it within the broader Chinese and Asian plastics-processing ecosystem, where machinery performance, energy efficiency, and line productivity are key procurement criteria.
Global Presence and Market Position
WUJIANG POLIMIROIR functions as the Chinese manufacturing base of a group that also operates in France, giving it a cross-border industrial structure rather than a purely domestic profile. The Polimiroir Group describes itself as active in several sectors, including plastics, steel, energy, aerospace, defense, and oil, while maintaining a strong international orientation.
In the plastics sector, the company competes in a niche defined by high-value, precision-engineered rolls rather than mass-market generic machinery. Its market position appears to rest on three attributes:
- Specialized coating and roll expertise
- Ability to serve large-format industrial components
- Integration into an established multinational roll group
The company’s participation in Chinaplas industry listings underscores its visibility in the Asian plastics equipment market and its alignment with trade-fair-based customer development in China.
Sustainability and Environmental Initiatives
Publicly available materials reviewed for this article do not provide detailed, quantified sustainability disclosures specific to WUJIANG POLIMIROIR. However, some implications can be drawn from its technology mix.
Thermal-spray surface treatment and roll refurbishment can support asset life extension by restoring worn industrial components rather than replacing them, which may reduce material consumption relative to full-component replacement. In plastics-processing plants, improved roll durability may also contribute indirectly to lower downtime and better process efficiency, although no company-specific environmental performance data were located in the available sources.
The company also operates within a broader group that advertises multiple surface-treatment technologies and industrial repair capabilities, which are generally consistent with circular-use practices in heavy manufacturing.
Financial Performance and Economic Impact
No audited financial statements or detailed revenue disclosures for WUJIANG POLIMIROIR were identified in the provided sources. One LinkedIn profile associated with the company states that revenue increased from zero to 10 million RMB during an early development period, but this figure is not independently verified in the sources reviewed and should be treated as an individual professional claim rather than a company filing.
Economically, the company contributes through localized high-skill manufacturing, precision coating services, and support for equipment productivity in downstream plastics production. Its ability to process large rolls domestically in China likely reduces lead times for regional customers and supports the localization of technical service for machinery operators in the film sector.
Leadership and Corporate Governance
Trade and company materials identify Huanhuan Mao as General Manager of WUJIANG POLIMIROIR. Public professional profiles also associate Olivier Peiffer with the leadership of the Wujiang entity and the broader Polimiroir group, although current corporate titles should be treated cautiously unless confirmed by formal company records.
The company states that it is certified to ISO 9001 and EN 9100, indicating formalized quality-management systems and a governance approach structured around process control, traceability, and consistency in high-precision manufacturing. Its association with the wider Polimiroir Group suggests a governance model shaped by group-level technical standards and international coordination.
Innovations and Future Outlook
The most notable innovation theme at WUJIANG POLIMIROIR is the application of advanced thermal-spray engineering to industrial rollers used in plastics processing. In practical terms, that innovation focus is less about consumer-facing product novelty and more about improving:
- Surface durability
- Wear resistance
- Service intervals
- Dimensional performance
- Process stability on continuous lines
The company’s references to a future or expanding plant in Wujiang indicate that it may be preparing for greater regional demand, particularly from Chinese and Asian OEMs operating in the oriented-film and coating segments. Broader industry trends that are likely to shape its outlook include demand for higher-performance packaging films, tighter process tolerances, and more durable roll surfaces that can withstand longer production runs with less maintenance.
