Introduction
LUNG MENG MACHINERY CO., LTD. (龍盟機械股份有限公司), also known as Dragon Plastic Machinery, is a Taiwanese manufacturer of plastics converting machinery headquartered in Yongkang District, Tainan City, Taiwan. Founded in 1976, the company specializes in integrated production systems for blown film extrusion, printing, bag making, laminating, recycling, and related converting processes, with a business model centered on turnkey and in-line automation for flexible packaging production.
The company is best known for its “All In Line System”, introduced in 1983, which connects blown film extruders, printers, and bag-making machines in a single production flow. This integration has been a defining feature of the company’s technical identity, allowing it to serve packaging manufacturers seeking higher throughput, lower labor dependence, and more streamlined production. Lung Meng’s product range includes single-layer and multi-layer blown film lines, zipper-profile extruders, flexographic and central-impression printing systems, bag-on-roll machines, sealing-and-cutting equipment, and recycling machinery.
Lung Meng operates from its Taiwan headquarters and has presented its machinery at major international plastics exhibitions, reflecting its export-oriented profile and global customer base. Available industry listings and company materials indicate that its equipment is used in food packaging, shopping bags, industrial bags, and recycling applications, positioning the company within the broader flexible packaging and plastics-processing machinery sector rather than as a resin producer or compounder.
History and Development
Lung Meng was established in 1976 as a professional manufacturer of plastics converting machinery in Taiwan. The company’s early focus was on machinery for plastic bag production, a segment that later expanded into broader film-converting and packaging systems.
A major development came in 1983, when the company launched the All In Line System. This system enabled blown film extrusion, printing, and bag-making to operate in-line, reducing intermediate handling and creating a more integrated manufacturing workflow.
Over time, Lung Meng expanded from standalone machinery into more comprehensive plant-level solutions. Company and trade-show descriptions indicate continued development of modular automated lines, including recycling and co-extrusion systems, reflecting the industry’s shift toward efficiency, process integration, and sustainability-oriented production.
Business Operations and Segments
Lung Meng’s business is concentrated in plastics processing machinery manufacturing, with emphasis on flexible packaging equipment.
Its core operational areas include:
- Extrusion systems for producing plastic film and related profiles
- Printing machinery used in packaging decoration and branding
- Bag-making and sealing equipment for converting film into finished bags
- Recycling machinery for handling plastic waste streams and reprocessing
- Integrated in-line production systems combining multiple process stages into one workflow
Trade and company directories also describe Lung Meng as engaged in manufacturing, domestic sales, export, and import-related activities, indicating a diversified commercial footprint within the machinery sector.

Technical capabilities
Company materials and industry listings describe systems ranging from compact laboratory-scale extruders to large multi-layer blown film lines, including a 3 x 150 mm co-extrusion configuration and wide-format film equipment. The company also offers bag-making formats such as bottom-seal, side-seal, double-bottom-seal, and one-side-opened seal machines, supporting products including T-shirt bags, patch-handle bags, zipper bags, pre-opened bags, square-bottom bags, and merchandise bags.
The technical value of Lung Meng’s systems lies in process integration. Its in-line concept links film extrusion, printing, and converting, which can reduce work-in-process inventory, improve consistency, and shorten production cycles. The company also emphasizes automation, modularity, and energy efficiency in its machine design.
Applications and End Markets
Lung Meng’s machinery serves the flexible packaging and plastics converting industries, rather than direct consumer markets.
Its equipment is used in:
- Food packaging
- Retail and shopping bags
- Industrial and heavy-duty bags
- Bag-on-roll products
- Recycling and reprocessing operations
These applications place the company in a segment shaped by both productivity demands and regulatory pressure on plastic packaging. Demand trends in this area increasingly favor machinery that can support material reduction, automation, recycled-content processing, and waste recovery. Lung Meng’s inclusion of recycling systems in its portfolio reflects this broader shift.
Global Presence and Market Position
Lung Meng is based in Tainan, Taiwan, with company listings also identifying a Taipei office. Trade-show records and supplier databases indicate participation in international exhibitions such as NPE and K Show-related events, suggesting an export-oriented strategy and sustained engagement with overseas buyers.
According to trade-directory material, the company has sold machinery to more than 120 countries and has used overseas sales agents in markets including Russia, Ukraine, Tunisia, India, and Turkey. Because this figure appears in supplier-profile material rather than audited reporting, it should be treated as a company claim rather than independently verified market data.
Publicly available information does not provide a reliable audited global market share, so Lung Meng is best characterized as a specialized international machinery supplier with a long-established niche in plastic bag and film converting systems.
Sustainability and Environmental Initiatives
Lung Meng’s sustainability profile is tied primarily to its machinery design rather than to downstream plastics production. The company states that its integrated systems are intended to improve productivity, reduce labor dependence, and support smart, sustainable manufacturing.
Its recycling machinery and process-integrated lines are the most directly relevant sustainability-oriented offerings, since they can support:
- Plastic scrap recovery
- Reprocessing of production waste
- Reduced handling through in-line integration
- Energy-conscious and modular plant design
As with many equipment suppliers in the plastics sector, the company’s environmental contribution is indirect: it provides machinery that can help customers operate more efficiently and incorporate recycled material streams, but its public materials do not disclose detailed emissions, lifecycle, or quantified decarbonization targets.
Financial Performance and Economic Impact
No audited public financial statements were identified in the supplied sources, and the company does not appear to publish detailed revenue or profit figures in the available material. As a privately held manufacturer, its financial performance is therefore difficult to assess from open sources.
Its economic impact is more visible through its role in Taiwan’s plastics machinery cluster and export trade. Company and trade listings show a long operating history, manufacturing presence in Tainan, and extensive international sales activity, all of which indicate participation in Taiwan’s broader precision machinery export base.
Leadership and Corporate Governance
Public registry-style sources identify Chen Chun-Shan as the company’s responsible person and list the firm as an approved private company established under Taiwanese corporate registration. Available materials also identify the company as LUNG MENG MACHINERY CO., LTD. with a registered address in Yongkang District, Tainan City.
The available sources do not provide a detailed board structure, executive team biography, or governance framework beyond registry and contact information.
Innovations and Future Outlook
Lung Meng’s main innovation pathway has been process integration. The All In Line System remains the company’s signature development, and its later emphasis on modular automated lines suggests a strategy built around:
- Higher production efficiency
- Reduced manual intervention
- Broader product-format flexibility
- Compatibility with recycling-oriented manufacturing
- Customizable turnkey packaging lines
Future prospects for the company are likely linked to industry demand for packaging machinery that can accommodate automation, recyclability, and changing regulatory expectations for plastic packaging. Its position in film, printing, bag-making, and recycling equipment places it within a segment where customers increasingly seek integrated systems that can manage both productivity and sustainability requirements.
