Introduction
ZHEJIANG DERZ MACHINERY CO., LTD. (浙江德企机械有限公司) is a Ruian, Zhejiang–based manufacturer of plastic packaging machinery, specializing in plastic film blowing extruders and bag making machines. The company operates in the plastics processing equipment segment of the industry, serving converters that produce flexible packaging materials and finished bags used in retail, industrial, and general-purpose packaging applications.
Founded in the late 2000s, Derz Machinery has positioned itself as a producer of machinery for film extrusion, co-extrusion, and bag fabrication, reflecting the close integration of polymer processing, packaging production, and downstream converting that characterizes China’s plastics machinery cluster in Zhejiang province. Public listings and supplier profiles also associate the company with slitting and printing machinery, indicating a broader packaging-equipment scope within its product portfolio.
History and Development
Zhejiang Derz Machinery is reported in supplier and product listings to have been established in 2008 or 2009, with one product profile giving a founding date of 2009-03-24. The company is located in Ruian, Wenzhou, an area widely known for packaging machinery manufacturing and supporting supply-chain networks.
Key development points include:
- The company began as a specialized manufacturer of plastic film blowing and bag-making equipment, rather than as a general industrial machinery producer.
- Its public product descriptions expanded from basic film-blowing machinery to multi-layer co-extrusion lines, including two-layer and three-layer film blowing systems.
- More recent supplier listings indicate product breadth across film blowing machines, bag making machines, slitting machines, and printing machines, suggesting an integrated packaging-equipment offering.
Business Operations and Segments
Derz Machinery describes itself as a joint-stock company engaged in the manufacture and sale of plastic film blowing extruders and bag making machines. Its business is centered on the equipment used to convert polymer resins into flexible film and then into bags or related packaging formats.
Its operations appear to cover:
- Research and development
- Equipment production
- Sales
- After-sales service
Supplier and marketplace profiles describe the company as a manufacturer and trade-oriented business active in the broader machinery for processing and packaging category. This is typical of many Chinese plastics machinery firms, which combine in-house design, production, and export-oriented sales functions.
Products and Technologies
Derz Machinery’s core products are film blowing machines and bag making machines. Public product descriptions identify several specific equipment types:
- Plastic film blowing machines
- Two-layer co-extrusion film blowing lines
- Three-layer co-extrusion film blowing lines
- High-speed bag making machines
- Slitting machines
- Printing machines
The company’s film-blowing equipment is intended for the production of polymer film used in packaging, with co-extrusion systems enabling multi-layer structures that can improve properties such as barrier performance, toughness, sealability, or processing flexibility, depending on the resin combination and line configuration. This is an inference based on the function of co-extrusion film-blowing technology, rather than a claim explicitly stated by the company.
A supplier profile also states that the company offers biodegradable plastic film blowing machines for materials such as PLA/PBAT, indicating attention to emerging lower-impact packaging materials. If accurate for the company’s active portfolio, this would place Derz Machinery within a segment of the machinery market responding to demand for compostable or bio-based packaging films.
Applications and End Markets
Derz Machinery’s equipment serves the flexible packaging value chain, where plastic films are used to make bags and other converted products. Typical end uses for this type of machinery include:
- Shopping and carrier bags
- T-shirt bags
- Vest bags
- Industrial packaging bags
- General flexible packaging film
The company’s product mix suggests a customer base among packaging converters, film processors, and small to mid-sized manufacturing operations that require integrated film-and-bag production capabilities. Its machinery is particularly relevant to markets where polyethylene-based packaging and multi-layer film structures remain common.
Global Presence and Market Position
Available sources indicate that Derz Machinery is headquartered in Gexiang Industrial Area, Ruian, Zhejiang, China. The company also maintains an English-language website and appears in multiple international B2B supplier platforms, suggesting export-oriented visibility beyond the domestic market.
Its market position appears to be that of a specialized regional machinery producer rather than a large multinational equipment group. The company’s competitiveness is likely based on the combination of:
- focused product specialization
- packaging-machinery cluster advantages in Zhejiang
- export marketing through digital supplier platforms
- customization and OEM/ODM-oriented manufacturing references in marketplace listings
Sustainability and Environmental Initiatives
Public materials connected to Derz Machinery mention biodegradable film blowing machines for PLA/PBAT, which indicates exposure to the growing market for more sustainable packaging machinery. This is significant because the plastics equipment sector is increasingly influenced by:
- demand for recyclable packaging structures
- interest in compostable or bio-based film materials
- pressure to improve material efficiency and reduce waste
No audited sustainability report or formal environmental target was identified in the available sources, so broader claims about the company’s environmental performance cannot be verified from the provided material.
Financial Performance and Economic Impact
No audited financial statements, revenue figures, or employee disclosures were identified in the provided sources. Available third-party supplier listings describe the company as relatively small in scale, with one source estimating a workforce of approximately 11 to 50 employees. That figure should be treated cautiously because it comes from a marketplace profile rather than a corporate filing.
Even without published financial data, the company’s economic role is clear within its niche: it contributes to the supply of machinery used by packaging processors, supporting downstream production of flexible plastic goods for domestic and export markets.
Leadership and Corporate Governance
Public sources identify the company as a joint-stock company, but they do not provide a detailed board structure, named executives, or governance disclosures. The company’s website and marketplace listings do show direct contact information and sales representation, indicating a conventional owner-managed or closely held industrial company structure typical of many mid-sized machinery manufacturers in China.
Innovations and Future Outlook
Derz Machinery’s most relevant innovation themes appear to be:
- multi-layer co-extrusion film technology
- high-speed bag making
- biodegradable-film machinery
- integration of printing and slitting into the packaging machinery offering
These product directions align with broader industry trends in plastics processing, including higher-output lines, more efficient conversion systems, and machine compatibility with alternative packaging materials. Future performance will likely depend on the company’s ability to maintain product reliability, support export customers, and adapt to changing packaging regulations and material preferences.
Summary
ZHEJIANG DERZ MACHINERY CO., LTD. is a specialized Chinese plastics machinery manufacturer focused on film blowing extruders, co-extrusion lines, and bag-making equipment. Based in Ruian, Zhejiang, the company operates within one of China’s important packaging-machinery manufacturing clusters and serves the flexible packaging supply chain through a product range that includes film, bag, slitting, and printing machinery.
