Flexo Non Woven Bag Printing Machine: Capabilities, Configurations, and OEM Considerations

Flexographic printing has become the dominant method for decorating non-woven bags in commercial production. A flexo non woven bag printing machine applies ink to PP spunbond fabric rolls using flexible polymer plates, enabling continuous roll-to-roll printing at speeds that match modern bag-making lines. This article explains what flexo non woven bag printing machines actually do, how they differ from screen printing, what configurations are available, and what buyers should evaluate before purchasing — with reference to the ZXH series produced by Zhejiang Zhengxin Machinery Co., Ltd.

What Is a Flexo Non Woven Bag Printing Machine?

A flexo non woven bag printing machine is a roll-to-roll press that prints logos, text, and designs onto non-woven fabric using flexographic technology. The machine uses a rotating printing cylinder with a flexible photopolymer plate, a metering roller (anilox roller), and a fountain roller to transfer ink onto the fabric as it passes through the press. Unlike screen printing, which is a batch process, flexo printing is continuous and can be integrated directly into a bag production line.

Zhejiang Zhengxin Machinery Co., Ltd. (Zhengxin) manufactures a range of non-woven bag printing machines under the ZXH series. The two flexo models in this range are the ZXH-C21200, a two-color flexo printing machine, and the ZXH-C41200, a four-color flexo printing machine. Both are designed for the roll-to-roll printing of non-woven fabric with a maximum fabric roll width of 1200 mm and a maximum printing width of 1160 mm.

Why Flexo Is the Standard for Non-Woven Bag Production

Flexo printing is preferred over screen printing and digital printing for most commercial non-woven bag orders because of speed, cost per bag, and compatibility with inline production.

Flexo vs screen printing

Screen printing is a slower, batch-oriented process. Semi-auto non-woven bag screen printing machines typically achieve speeds of 20–40 pcs/min with a max area of 500×600 mm. Flexo printing operates in a continuous roll-to-roll mode, so printed fabric can be fed directly into a bag-making machine without a separate handling step. The ZXH-C21200 and ZXH-C41200 both run at 10–60 m/min, which keeps pace with typical non-woven bag line speeds.

Screen printing is often chosen for very thick ink layers, specialty effects, or short runs where flexo plate setup is not economical. But for standard shopping bags with one to four colors, flexo is the more productive and cost-efficient option.

Flexo vs digital printing

Digital printing offers design flexibility but has higher ink costs and slower speeds. In commercial bag economics, flexo ink cost per bag is significantly lower at order volumes above 500 bags per design. At scale — for example a run of 100,000 bags of the same design — flexo's per-bag ink cost remains a fraction of the digital alternative, and the speed advantage avoids bottlenecks in the bag-making workflow. Water-based flexo inks also meet food-contact and eco-friendly requirements, a growing consideration for retailers and food delivery brands.

Available Configurations: 1, 2, 3, 4, and 6 Color Flexo

Non-woven bag printing needs vary by market and order type. A promotional bag producer may need frequent design changes with one or two colors, while a large-scale shopping bag manufacturer supplying supermarket chains may need four or more colors to reproduce brand logos accurately.

In the context of the ZXH series, Zhengxin offers two standard flexo models: the 2-color ZXH-C21200 and the 4-color ZXH-C41200. Beyond these standard machines, Zhengxin supports customization of printing colors across its flexo line. The company's engineering team can configure flexo non woven bag printing machines from 1 to 6 colors, depending on the production requirement. This allows buyers to start with a 1-color or 2-color machine and expand later, or to commission a multicolor machine for higher-value packaging.

Matching color count to application

• 1-color flexo — suitable for simple logo prints, one-color branding, and basic text on supermarket shopping bags.
• 2-color flexo — covers the majority of retail logos where two spot colors are used. The ZXH-C21200 is the recommended entry point for most bag producers.
• 3-color flexo — used when a design includes a third spot color or a simple combination of logo + text + accent.
• 4-color flexo — suitable for premium brands, promotional bags, and multi-color designs. The ZXH-C41200 offers four-color capability in a single pass.
• 6-color flexo — for complex branding, gradients, and higher-end packaging where more colors are needed on the same roll.

On the screen printing side, Zhengxin also produces the ZXH-A1200 (1-color screen printing machine) and the ZXH-B1200 (2-color screen printing machine) for buyers whose product mix favors screen printing.

Integration With Non-Woven Bag Production Lines

A flexo non woven bag printing machine is most valuable when it is integrated into the overall production flow. Roll-to-roll flexo printing happens first: the fabric is unwound from a master roll, printed, dried, and rewound. The printed fabric roll is then transferred to a bag-making machine such as the ZXL series, which folds, seals, cuts, and attaches handles to produce finished bags.

For example, a manufacturer producing food takeaway bags and multi-color promotional shopping bags for retail malls in Egypt operates a line that includes two ZXH-C21200 flexo printing machines alongside ZXL-E700 and ZXL-D700 bag-making machines. In this configuration, the same supplier provides both printing and bag-making equipment, which simplifies procurement, maintenance, and operator training.

In an Indonesian production group operating 42 Zhengxin machines, the installed fleet includes 12 ZXH-A1200 screen printing machines used for multicolor printed promotional bags and food-grade takeaway packaging. This example illustrates that large producers often combine flexo and screen printing depending on their order mix.

Customization and OEM/ODM Capabilities

OEM and ODM services are available from Zhengxin. These options are relevant for buyers who want to sell machines under their own brand, require customized machine color and branding, or need a machine configured for a specific local market.

Zhengxin supports customization across multiple dimensions: printing colors (1–6 color flexo printing, single-side or double-side), voltage and power (220V / 380V / 415V / 440V, single-phase or 3-phase), control system (Siemens, Mitsubishi, or Delta PLC with multi-language HMI), material compatibility (PP spunbond, laminated non-woven, biodegradable fabric, 30–150 GSM), bag size and dimensions, and optional modules such as gusset makers, hole punches, folding units, and bundling systems.

For a buyer evaluating a flexo non woven bag printing machine, the practical application of OEM/ODM is threefold:

• Volume users can have the machine built to their preferred electrical standards and control components, reducing the need for local electrical conversion.
• Distributors and local brands can rebrand the machine and add their own after-sales service layer.
• Production lines can be specified with a unified PLC brand across printing and bag-making machines, simplifying spare parts inventory and operator training.

The minimum order quantity (MOQ) is 1 unit. This makes OEM/ODM or custom configuration accessible even for a first-time buyer purchasing a single machine.

Procurement Considerations for Flexo Non-Woven Bag Printing Machines

Buyers evaluating a flexo non woven bag printing machine should structure their assessment around the following criteria.

1. Color count and future flexibility

If a producer expects to print supermarket logos in one or two colors, a 2-color machine such as the ZXH-C21200 is a reasonable starting point. If the customer base includes premium brands with multi-color logos, a 4-color machine such as the ZXH-C41200 provides more headroom without requiring a future upgrade.

2. Fabric width and printing width

The ZXH series supports a maximum fabric roll width of 1200 mm and a maximum printing width of 1160 mm. Printing length is up to 1000 mm. Buyers should verify that these dimensions match the bag sizes they intend to produce and the fabric rolls they plan to source.

3. Printing speed and line balance

Printing speed on the ZXH-C21200 and ZXH-C41200 is 10–60 m/min. The printing station should not become the bottleneck in the total production line. Buyers should compare the printing speed with the capacity of the bag-making machines feeding the line.

4. Material range

Flexo machines must handle the fabric GSM range the producer works with. The ZXH flexo models support non-woven materials from 60–150 g/㎡ (screen models support different ranges). Laminated fabrics and biodegradable substrates may require different ink systems or drying settings.

5. Certification and compliance

Zhengxin's printing machines carry CE certification (Machinery, Low Voltage, and EMC Directives), and the factory is ISO 9001:2015 certified. The CE scope for the ZXH-C series includes ZXH-C21200 and ZXH-C41200. Buyers shipping to the EU, Middle East, Africa, and other CE-accepting regions should verify that the certificate matches the machine model.

6. Component quality

Zhengxin uses genuine branded components — Siemens, Delta, or Mitsubishi PLCs, Omron sensors, and NSK bearings — and allows third-party pre-shipment inspection by SGS, Bureau Veritas, or CCIC upon request. For a printing machine where registration accuracy depends on sensors and drives, component quality has a direct effect on print consistency.

Market Context and Trends

The global flexographic printing machine market was valued at USD 17.57 billion in 2024, with a projected CAGR of 9.7% through 2030. This growth reflects the continuing adoption of flexo for packaging applications, including non-woven bags. Flexographic printing machines are also preferred for eco-friendly water-based inks, which can reduce VOC emissions by up to 80% compared with solvent-based systems — a meaningful advantage for bag producers selling to retailers and food brands with environmental procurement policies.

Regulation is another demand driver. Over 100 countries have implemented bans or taxes on single-use plastic bags. As retailers move to reusable non-woven bags, the need for printed branding on those bags rises, increasing demand for efficient printing equipment. Asia-Pacific dominated the bag making machine market with a 43.6% revenue share in 2025, and China exported 1.52 million tons of nonwovens in 2024, valued at USD 4.04 billion — evidence of a mature upstream supply chain for non-woven fabric producers.

Within this market, the shift is toward automatic, integrated lines. The automatic segment of the bag making machine market held a 52.4% share in 2025. Producers are increasingly buying full lines — printing, bag-making, handle attachment, stacking — from a single supplier, as seen in Zhengxin's multi-machine deployments in Egypt, Indonesia, Kenya, Brazil, and Tanzania.

Comparison With Traditional Solutions

Compared with traditional screen printing, a flexo non woven bag printing machine offers faster throughput, continuous roll-to-roll operation, lower per-bag ink cost, and easier integration with an automatic bag production line. For multi-color work, flexo also produces consistent registration across long runs.

The trade-off is that flexo requires a dedicated plate for each design and each color. Plate making adds setup time and cost, so very short runs — for example 100–500 bags of a unique design — are more economically printed on digital equipment or handled by screen printing. Flexo also has practical limits on ink film thickness. Effects that require a very heavy ink deposit, such as certain tactile or specialty finishes, are better suited to screen printing.

Buyers who primarily produce short-run promotional orders with frequent artwork changes may find flexo changeover costs too high. In that case, a hybrid approach — basic flexo for volume orders and a smaller screen printing machine for short-run jobs — is a practical configuration.

Future Outlook

Because the ZXH flexo printers support roll-to-roll production and can be paired with bag-making machines from the same manufacturer, the direction of new bag factories is increasingly toward single-supplier integrated lines. New buyers can start with a 2-color flexo machine, validate demand for printed bags, and then add a 4-color unit or a screen printing machine as the order mix evolves.

Zhengxin's business model supports this staged growth path. With a 60,000 m² factory, an engineering team of 30, and an annual output of approximately 500 units, the company delivers both standard machines and custom configurations. For buyers evaluating a flexo non woven bag printing machine, the practical question is not simply which color count to choose, but which supplier can support the machine over its full service life — with spare parts, operator training, and service in multiple regions. Zhengxin has offices in Kenya, Morocco, Egypt, Vietnam, Tanzania, Dubai, Oman, Indonesia, and Ethiopia, which is a relevant consideration for buyers in those markets.
