Introduction
XINFU GUANLONG PLASTICS MACHINERY CO., LTD. (Chinese: 山东莱芜新甫冠龙塑料机械有限公司) is a Chinese plastics machinery manufacturer based in Laiwu, Jinan, Shandong Province, with a business focus on plastic extrusion and film-production equipment for agricultural, geotechnical, packaging, pipe, and related industrial applications. The company presents itself as an integrated enterprise engaged in research and development, design, manufacturing, and service for plastic machinery, and it has built particular recognition around multilayer co-extrusion film lines and specialized equipment for agricultural films and geosynthetics.
In the broader plastics industry, the company occupies the segment of downstream equipment supply, where machinery makers translate polymer resin into films, pipes, profiles, and technical materials used across agriculture, infrastructure, packaging, and industrial processing. Its portfolio indicates a technical orientation toward multilayer extrusion, blown-film systems, and customized production lines, including equipment for greenhouse film, agricultural mulch film, geomembrane, drip irrigation, packaging film, and EPE foam production.
History and Development
Shandong Laiwu Xinfu Guanlong Plastic Machinery Co., Ltd. was founded in 2006, according to company and business-directory records. The enterprise is also listed as a manufacturer and factory engaged in plastics machinery and film-blowing equipment, suggesting an early emphasis on industrial production rather than trading alone.
A notable development milestone was the company’s creation of a five-layer co-extrusion plastic film unit, which its own materials describe as having been developed by Xinfu and selected for inclusion in China’s 13th Five-Year Plan industrial context. This is significant because five-layer co-extrusion equipment is a higher-value segment of film machinery, supporting improved barrier properties, mechanical performance, and material efficiency compared with simpler single-layer systems.
A second milestone is the company’s reported work on online roughening equipment for geomembranes, which was recognized in industry reporting as a Chinese first, received a patent-related award, and was described as reaching an advanced international level. A third milestone is the reported development of a seven-layer co-extrusion blown-film unit, which industry coverage said passed expert appraisal in 2024 and filled a domestic gap.
The company’s development has also been supported by collaboration with academic and research institutions, including reported cooperation with Shandong Agricultural University and the Shanghai Research Institute of Chemical Industry, which indicates a model that combines in-house manufacturing with external technical support.
Business Operations and Segments
The company’s core business is the manufacture of plastic machinery and complete production lines. Its product mix suggests several operating segments:
- Film extrusion systems for agricultural, greenhouse, packaging, and specialty films.
- Geosynthetics equipment, including geomembrane and related coating or lamination systems.
- Pipe and irrigation-line equipment, including plastic pipes, drip irrigation, and water-supply belt machinery.
- Auxiliary and specialty lines for foam, sheet, profile, granulation, and drawing applications.
The company also states that it can provide custom design, production, and equipment retrofitting according to user requirements, which is typical of machinery suppliers serving project-based industrial buyers rather than standardized consumer markets.
Products and Technologies
The company’s product range is centered on extrusion-based plastic processing equipment. Its documented product categories include:
- Plastic extruders
- Agricultural film equipment
- Greenhouse film equipment
- Geotechnical film equipment
- Packaging film equipment
- Heat-shrink film equipment
- Plastic pipe machinery
- Drip irrigation belt equipment
- Air-cushion film equipment
- Profile and sheet machinery
- Pelletizing and drawing lines
- EPE butane foaming lines
Among these, the most technically notable systems are the company’s multilayer co-extrusion film lines. In plastic film production, multilayer systems combine different polymers or blends in a single structure, allowing manufacturers to optimize strength, sealing behavior, clarity, barrier properties, or cost efficiency for the target application. The company specifically highlights five-layer greenhouse film equipment and seven-layer blown-film technology, indicating capability in advanced co-extrusion architecture.
Its geomembrane-related equipment is also technically important because geotechnical films often require controlled thickness, improved surface characteristics, and consistent mechanical performance for infrastructure and environmental engineering use. The company’s reported online roughening machine for geomembranes suggests specialization in surface treatment processes that improve frictional behavior and installation performance.
Applications and End Markets
The company’s machinery serves several downstream plastics markets:
- Agriculture, including mulch film, greenhouse film, drip irrigation, and water belt systems.
- Civil engineering and infrastructure, including geomembranes and geotechnical materials.
- Packaging, including packaging film and heat-shrink film lines.
- Building and construction, through pipe, profile, and sheet equipment.
- Industrial processing, including pelletizing, drawing, and EPE foam systems.
Its emphasis on agricultural film and geosynthetics aligns with broader Chinese plastics demand patterns, where film extrusion equipment supports both agricultural productivity and infrastructure development. The company’s technical positioning therefore bridges commodity film machinery and more specialized, higher-performance systems.
Global Presence and Market Position
The company states that it holds self-operated import and export rights, indicating direct participation in international trade. Industry coverage also states that its products have been sold to more than 30 countries, suggesting a meaningful export footprint for a specialized Chinese machinery maker.
Business-directory sources describe the company as a high-tech enterprise with strong development capabilities, and one industry profile identifies it as a member of sectoral organizations connected with agricultural film, agricultural plastic products, and geosynthetics engineering. These affiliations place the company within niche but strategically important segments of the plastics machinery industry.
Research and Development
R&D appears to be central to the company’s identity. Company materials describe a team of experienced plastics machinery professionals and emphasize continuous introduction of new technologies and product development. The enterprise has also reported cooperation with universities and research institutions, which supports incremental product improvement and adaptation to customer-specific requirements.
Patent-related reporting indicates that the company has accumulated a substantial intellectual-property base. One business profile reports 34 patents, while industry reporting later states the company had more than 40 invention and utility model patents. The difference likely reflects changes over time and different reporting cutoffs, but both sources indicate a patent-active machinery developer rather than a purely assembly-oriented manufacturer.
Quality Management and Certifications
Industry reporting says the company has obtained ISO 9001 quality management certification and ISO 14001 environmental management certification. These certifications are relevant in machinery manufacturing because they indicate formalized controls over production quality and environmental management systems.
The same reporting describes the company as a national high-tech enterprise and a specialized and sophisticated enterprise in Shandong Province, which suggests recognition within China’s policy framework for technology-oriented industrial firms.
Sustainability and Environmental Initiatives
The company’s equipment portfolio includes systems related to degradable agricultural film, which is relevant to industry efforts to reduce persistent plastic waste in farming applications. It also produces machinery for geotechnical materials and drip irrigation, both of which can support more efficient land and water use in agriculture and infrastructure projects.
From an industrial perspective, the move toward multilayer co-extrusion can also contribute to material efficiency by enabling thinner structures or improved performance with less resin, although the environmental outcome depends on the end product and how it is used. The company’s ISO 14001 certification further suggests that environmental management is part of its operational framework.
Innovation and Future Outlook
The company’s most important innovation trajectory is its move from conventional film lines toward advanced multilayer extrusion systems and specialized production equipment for geomembranes and agricultural technical films. That direction matches broader plastics-industry demand for more efficient, higher-performance machinery capable of producing films with tighter tolerances and more complex layer structures.
Its combination of custom engineering, patent development, and international sales positions it as a regional machinery maker with technical depth in selected niches rather than a mass-volume generalist. Future competitiveness in this segment is likely to depend on continued progress in automation, energy efficiency, process stability, and application-specific line design for agriculture, infrastructure, and packaging markets.
