Introduction
CHANGLONG SCIENCE & TECHNOLOGY（YANGJIANG）CO., LTD. is a Chinese manufacturer of plastics processing machinery based in Yangjiang, Guangdong Province. The company is associated with the development, production, and export of cast film lines, stretch-wrap film equipment, protective film machinery, PE cling film machines, and rewinding and slitting systems, placing it within the industrial segment of the plastics equipment market rather than the production of polymers themselves.
Founded in 2013, the company has built its business around fully automated film-processing equipment and related production lines, with a profile that emphasizes in-house manufacturing capability and international sales. Industry and exhibition listings indicate that its machines are used across a broad width range, with product coverage extending from 500 mm to 3,000 mm and applications in single-layer and multi-layer cast film production. The company is also listed in multiple international exhibition and business directories, including ChinaPlas-related and advanced manufacturing exhibitor platforms, reflecting its presence in plastics machinery trade channels.
History and Development
The company was established on 9 April 2013 in Yangjiang, Guangdong, according to business-profile sources. Its core development path has centered on cast film machinery and allied converting equipment, with a product portfolio described as integrating research and development, design, manufacturing, sales, and after-sales service.
A second development milestone is the company’s emphasis on high in-house parts production, with one business profile stating that roughly 90% of components are self-manufactured except for electrical and drive motors. That manufacturing model is significant in machinery supply chains because it can improve process control, shorten lead times, and support product consistency.
A third milestone is the company’s increasing international visibility. The company appears in exhibition and industry directories connected to major plastics trade events, and trade-data references associate it with exports or shipments to markets outside China, including customers in global packaging and plastics machinery supply chains.
Business Operations and Segments
The company operates as a specialized equipment manufacturer serving the plastics film sector. Its activities appear to cover:
- Equipment development and design
- Machine manufacturing and assembly
- Sales and export
- Service and technical support
Its business is oriented toward conversion equipment used by packaging and film processors, rather than downstream consumer goods or upstream resin production. This places the company in the plastics value chain as an equipment supplier supporting film extrusion, stretching, wrapping, and finishing operations.
Products and Technologies
The company’s identified product lines include:
- CPE cast film line equipment
- Stretch-wrap film production lines
- Protective film machinery
- PE cling film machines
- Rewinding and slitting machines
Its cast film systems are described as covering single-layer and multi-layer configurations, with widths from 500 mm to 3,000 mm. In practical machinery terms, this suggests capability across both narrower specialty film formats and wider industrial packaging films.
The reported product mix indicates exposure to several technical functions common in film converting:
- Cast film extrusion, in which molten polymer is formed into a film sheet on a chilled roll.
- Orientation or stretching processes for stretch film applications.
- Slitting and rewinding, which are essential for converting master rolls into commercial formats.
- Protective-film production, which typically emphasizes surface quality, gauge stability, and controlled winding performance.
A source on the company’s technology profile states that the firm self-manufactures a high share of parts, implying a vertically integrated machine-building approach. In plastics machinery, this can be relevant for precision, repeatability, and serviceability, especially in line components where dimensional accuracy and stable operation affect film quality.
Applications and End Markets
The company’s equipment is directed primarily toward packaging and film-processing applications. The main end uses implied by its product range include:
- Stretch wrap for pallet and logistics packaging
- Cling film for food-related wrapping applications
- Protective film for surface protection in industrial or consumer goods
- Cast film production for downstream converting and packaging uses
These applications align the company with markets that depend on thin-film plastic processing, including logistics, food packaging, industrial packaging, and protective materials.
Global Presence and Market Position
Business and trade sources describe the company as exporting to a wide range of markets, with one profile stating that its products reach more than 80 countries and regions, including Europe, Southeast Asia, and the Middle East. Trade directory references also associate the company with overseas buyers and shipment records in global import-export databases.
Its market position appears to be that of a specialized film-machine supplier rather than a diversified conglomerate. Participation in international exhibitor directories and industry platforms suggests an export-oriented strategy and a focus on visibility in plastics machinery trade networks.
Research and Development
The company’s profile emphasizes R&D, design, and manufacturing integration in its film machinery business. In machinery manufacturing, this type of integrated structure typically supports iterative engineering of line stability, film-width flexibility, and process consistency.
A patent-oriented company profile states that the company has accumulated 27 patents. While the specific patent subjects are not detailed in the available material, the number indicates a measurable technical development footprint in plastics machinery design and related systems.
Sustainability and Environmental Initiatives
The company’s identified product focus is concentrated on equipment used to produce packaging films, which places it within broader industry debates about plastic packaging, recyclability, and material efficiency. For machinery suppliers, sustainability often depends less on direct resin production and more on whether equipment can help processors reduce waste, improve gauge control, and manufacture thinner films with consistent performance.
The available sources do not describe formal environmental programs, but the company’s technical orientation toward automated film production and converting equipment is relevant to industry-wide efforts to improve material efficiency in packaging lines.
Certifications and Industry Recognition
The company is listed on Chinaplas-related and other industry platforms, and one exhibitor profile labels it a “Shining Niche” Company, indicating recognition within a specialized industrial category. It also appears in exhibitor lists connected to the China International Supply Chain Expo for 2024 and 2025, reflecting participation in advanced-manufacturing and supply-chain forums.
Financial Performance and Economic Impact
No audited financial figures are identified in the cited materials. Based on the available evidence, the company’s economic significance lies in its role as a producer of plastics film machinery, supporting film converters and packaging producers through equipment supply, technical service, and export activity.
Its in-house manufacturing model and international customer base suggest participation in the broader export-oriented machinery ecosystem in Guangdong, a region with strong plastics equipment and manufacturing supply chains.
Innovations and Future Outlook
The company’s future prospects are linked to demand for automated film production lines, packaging efficiency, and specialized cast-film applications. In the plastics machinery sector, future competitive strength typically depends on line stability, energy efficiency, service responsiveness, and the ability to customize equipment for different film grades and widths.
Its exhibition presence and patent activity indicate continued engagement with product development and industrial networking. For a company in this niche, future performance will likely be shaped by global packaging demand, export conditions, and the pace of technological upgrading in film converting equipment.
