Introduction

Nanjing Jieyang Machinery Co., Ltd. (南京捷阳机械有限责任公司) is a Nanjing-based Chinese manufacturer of specialized machinery for the production and packaging of drinking straws and related small-format plastic products. The company originated as Nanjing Chenyang Plastic Machinery Factory in 2003 and was formally established under its present name in 2008. Its portfolio encompasses extrusion, forming, bending, inspection, packing, and auxiliary equipment for conventional polypropylene straws, biodegradable-material straws, paper straws, oral-liquid straws, and plastic folding spoons.

Jieyang occupies a specialized position within the plastics-machinery sector. Rather than producing commodity polymers or broad ranges of injection-moulding and extrusion equipment, it concentrates on integrated, application-specific systems for high-volume disposable and food-service products. Its development reflects wider changes in the packaging industry, including the continued demand for automated converting equipment, the adoption of paper and biodegradable materials, and the need for more consistent inspection and packing operations.

The company is headquartered in Nanjing, Jiangsu Province, and presents itself as an equipment manufacturer and complete-line solution provider. Its business combines mechanical design, extrusion technology, downstream forming, automation, and packaging integration. Public company information identifies its main facility and office at the Yuhua Economic Development Zone in Nanjing.

History and Development

Jieyang’s development can be outlined through several identifiable milestones:

2003: The business began as Nanjing Chenyang Plastic Machinery Factory, initially focusing on plastic-machinery production and drinking-straw equipment.
2008: The company was formally established as Nanjing Jieyang Machinery Co., Ltd., providing a corporate structure for the expansion of its manufacturing and export activities.
Subsequent development: Its product range broadened from individual straw-making machines to integrated lines incorporating extrusion, bending, packaging, automatic inspection, and carton-packing functions.
Recent product expansion: The company has promoted equipment for PLA and PHA biodegradable straws, paper straws, oral-liquid multi-edge straws, and plastic folding-spoon packaging, responding to changes in material selection and packaging formats.

This progression follows a broader pattern in Chinese plastics machinery, in which specialist manufacturers have moved from supplying stand-alone machines toward complete production systems with greater automation and process coordination.

Business Operations and Segments

Jieyang’s activities are concentrated in machinery for small-diameter extrusion products and their downstream packaging. The principal operating areas are:

Straw extrusion equipment: Systems for producing continuous straw tubing from thermoplastic materials.
Straw forming and bending machinery: Equipment for shaping, bending, and finishing straws used in beverage applications.
Biodegradable-straw equipment: Machinery configured for materials such as PLA and PHA, whose processing characteristics differ from those of conventional polypropylene.
Paper-straw machinery: Equipment for forming and processing paper-based drinking straws.
Packing machinery: Individual, grouped, and secondary packaging systems for straws and related products.
Inspection and end-of-line automation: Automatic inspection machines and carton packers intended to reduce manual handling and improve production consistency.
Special-purpose equipment: Machinery for oral-liquid multi-edge straws and plastic folding-spoon packaging.

The company therefore participates in several layers of the plastics-processing value chain: material conversion, secondary forming, quality control, packaging, and logistics preparation.

Products and Technologies

Straw extrusion lines

Straw extrusion is the core of Jieyang’s product offering. In a typical line, polymer pellets are plasticized in an extruder, forced through a die to form a tube, cooled and calibrated, hauled continuously, and cut to length. Depending on the product specification, the line may also incorporate printing, bending, individual wrapping, bundling, or inspection.

The equipment is applicable to common straw materials such as polypropylene and to selected bio-based or biodegradable polymers. Processing biodegradable materials generally requires attention to melt temperature, residence time, moisture control, dimensional stability, and the mechanical properties of the finished tube. These considerations are particularly relevant for PLA, which has a narrower processing window and different thermal behavior from polypropylene.

Straw forming and bending

Bending machines create articulated or angled straw geometries, including the familiar flexible beverage straw. The forming operation must maintain the internal passage, avoid excessive wall deformation, and produce repeatable crease or hinge patterns. Production-line integration can connect extrusion, cutting, bending, and packing operations in sequence.

Paper-straw equipment

Paper straws require a different manufacturing route from polymer extrusion. Paper is typically converted by winding or wrapping multiple layers around a mandrel, followed by adhesive bonding, sizing, cutting, and finishing. Machinery designed for this application must control paper tension, adhesive distribution, alignment, drying, and dimensional accuracy. Jieyang’s inclusion of paper-straw equipment reflects the food-service industry’s movement toward alternatives to conventional single-use plastic straws.

Packaging machinery

Packaging systems form an important part of the company’s integrated offering. Depending on the product, packaging may involve:

Individual wrapping of straws;
Bundling or grouping;
Sealing into film or paper-based packs;
Packaging of oral-liquid straws;
Folding-spoon packaging;
Carton packing for secondary distribution.

Packaging automation can improve line speed and repeatability while reducing direct operator contact. It also supports traceability and standardized presentation for export and food-service customers.

Inspection and auxiliary equipment

Automatic inspection equipment can be used to identify dimensional defects, incomplete forming, contamination, printing irregularities, or packaging faults. Auxiliary equipment supports material feeding, cooling, conveying, counting, and transfer between processing stages. In a complete line, these components help synchronize throughput between extrusion, forming, inspection, and packing.

Applications and End Markets

Jieyang’s machinery serves manufacturers supplying disposable and semi-disposable products to several application sectors:

Beverage and food-service packaging;
Restaurants, cafés, hotels, and catering operators;
Dairy and drink products requiring individually packed straws;
Oral-liquid and pharmaceutical-related packaging formats;
Institutional and vending-channel consumption;
Retail and export packaging;
Producers of biodegradable and paper-based alternatives to conventional plastic straws.

The company’s equipment is linked closely to the economics of high-volume, low-unit-cost products. Customers typically require stable output, low scrap rates, reliable cutting and sealing, rapid changeovers, and compatibility with packaging specifications imposed by food-service or consumer-goods purchasers.

Global Presence and Market Position

Jieyang is based in Nanjing, an industrial and commercial center in eastern China with access to the Yangtze River Delta manufacturing and logistics network. Its published contact information places the company in the Yuhua Economic Development Zone.

The company markets its machinery internationally through English-language product materials, overseas business contacts, and industrial-platform listings. Its presence on the Chinaplas eMarketplace identifies it as a plastics-and-rubber industry exhibitor and describes the company under the category of specialized straw and packaging equipment. Commercial listings also associate it with straw extrusion machines, straw-bending machines, straw-packing machines, biodegradable-straw equipment, and spoon-packing machinery.

Jieyang’s competitive position is best understood as that of a niche machinery supplier specializing in a defined product family. Its differentiation derives from the combination of:

Concentrated technical experience in drinking-straw production;
Equipment for multiple material classes, including plastics, biodegradable polymers, and paper;
Integration of primary production with downstream packaging;
Support for specialized formats such as flexible, oral-liquid, and multi-edge straws;

Its market environment includes both specialized Chinese machinery manufacturers and larger international suppliers offering broader packaging or extrusion portfolios. Competition is influenced by equipment reliability, product consistency, energy consumption, service responsiveness, spare-parts availability, and the customer’s required material and packaging format.

Research and Development

Jieyang’s research and development activities are closely connected to process adaptation and product-format expansion. The company’s stated focus on multiple straw materials requires machinery configurations that accommodate different melt properties, thermal sensitivities, dimensional tolerances, and finishing requirements.

Relevant development areas include:

Extrusion systems adapted to PLA, PHA, and other biodegradable materials;
Improved control of tube diameter, wall thickness, and cutting accuracy;
Integration of bending, inspection, and packing into continuous production lines;
Equipment for paper-straw forming and adhesive-based construction;

Packaging systems for specialized products such as oral-liquid straws and folding spoons.

For a specialist machinery company, research and development is primarily application-driven. The commercial objective is not only to develop individual machines but also to ensure that the entire line operates within a stable and economically viable production window.

Sustainability and Environmental Initiatives

The company’s sustainability relevance arises mainly from its machinery for alternative straw materials. Its published product portfolio includes PLA and PHA biodegradable-straw equipment and paper-straw equipment, alongside machinery for conventional polypropylene straws. This enables manufacturers to select equipment according to changing legislation, customer requirements, waste-management systems, and material economics.

The environmental implications of these products require a balanced assessment:

Material substitution: Paper and biodegradable polymers can reduce reliance on conventional fossil-based plastics in selected applications.
Processing requirements: Alternative materials may require different temperatures, drying conditions, adhesives, or line speeds, affecting energy use and operating cost.
End-of-life conditions: The environmental performance of biodegradable materials depends on the specific polymer, local collection systems, and the availability of suitable industrial composting or recycling infrastructure.
Product-life considerations: A material substitution does not by itself determine total environmental impact; durability, material quantity, manufacturing energy, transport, and disposal conditions also matter.
Automation and waste reduction: Accurate extrusion, cutting, inspection, and packing can help reduce defective products and process waste.

Jieyang’s equipment therefore supports the transition toward alternative materials but does not independently determine the environmental performance of the finished straw. That outcome depends on material formulation, production conditions, product design, and waste-management systems.

Financial Performance and Economic Impact

Jieyang is a privately held specialist machinery company, and the publicly accessible company information emphasizes products, technical capabilities, and contact details rather than a detailed set of financial statements. Its economic significance is consequently most apparent through its role in the machinery supply chain.
