Langdi 960 High-Speed Industrial Inkjet Printer: The Complete Coding Solution for Food, Pharma, and Packaging
In the fast-moving world of packaging and production, every product that leaves your line needs to carry clear, accurate, and traceable information. Dates, batch numbers, serial codes, and increasingly, variable QR codes are no longer optional extras — they are regulatory requirements and consumer trust signals. The Langdi 960 High-Speed Industrial Inkjet Printer is built to meet that challenge head-on, combining fully automatic operation, high-speed output, and support for variable 2D codes in a compact 21 kg package.
Whether you run a pharmaceutical plant, a food and beverage factory, a cosmetics brand, or an electronics assembly line, the 960 is designed to keep up with your pace without sacrificing print quality. This article breaks down what makes it a smart investment for manufacturers, packagers, and OEMs.
What Is the Langdi 960?
The Langdi 960 is a fully automatic industrial continuous inkjet (CIJ) coding machine engineered for high-speed, non-contact printing on moving production lines. It prints dates, batch codes, lot numbers, serial numbers, and variable QR codes directly onto packaging, containers, and industrial materials — no labels, no plates, no downtime for changeovers.
With a working weight of just 21 kg, it is easy to integrate into existing conveyor systems, compact production cells, and space-constrained lines where larger coding equipment simply cannot fit.
Key Features of the Langdi 960 Industrial Inkjet Printer
1. High-Speed, Fully Automatic Operation
The 960 is built for continuous production lines. Once configured, it codes products automatically as they pass the print head, eliminating manual labelling steps and reducing labor costs on high-volume runs.
2. Variable QR Code and 2D Code Printing
Modern traceability demands more than a static stamp. The Langdi 960 supports variable data printing, including unique QR codes, DataMatrix-style 2D codes, serialized numbers, and changing date and batch information — ideal for anti-counterfeiting, supply chain tracking, and regulatory compliance.
3. Non-Contact Inkjet Technology
Because the print head never touches the substrate, the 960 can code irregular shapes, curved surfaces, tubes, cables, and flexible packaging without smudging or damaging the product.
4. Compact 21 kg Design
Light enough for mobile or modular setups and robust enough for round-the-clock industrial use, the 21 kg frame reduces floor space requirements and simplifies installation.
5. Multi-Industry, Multi-Material Versatility
One machine can handle multiple product lines, reducing the need for dedicated coders per line and lowering total cost of ownership.
Industries That Use the Langdi 960
The Langdi 960 is a cross-industry workhorse. Its most common applications include:
- Food and Beverage: Production and expiry dates on cartons, bags, bottles, and secondary packaging.
- Pharmaceuticals: Batch numbers, manufacturing and expiry dates, and traceability codes on medicine boxes and packaging.
- Cosmetics and Personal Care: Date and batch coding on tubes, jars, and cartons.
- Electronics: Serial numbers and QR codes on components and packaging.
- Automotive Parts: Part numbers, lot codes, and 2D codes for traceability and warranty tracking.
- Chemicals and Industrial Goods: Batch and safety information on chemical bags and drums.
Materials the Langdi 960 Can Print On
Material compatibility is one of the most important factors when choosing a coding machine. The Langdi 960 performs reliably on:
- Corrugated and cardboard cartons
- Plastic and foil packaging bags
- Chemical and industrial bags
- Pharmaceutical packaging materials
- Coated paper (铜版纸) and kraft paper bags (牛皮纸袋)
- Tubes, pipes, and profiles
- Cables, wires, and electronic components
- Daily-use consumer products and general packaging
Real-World Use Cases
Pharmaceutical Manufacturing
Pharma producers face strict requirements for batch and expiry coding. The Langdi 960 prints highly legible dates and lot numbers directly on medicine cartons, blister packs, and outer packaging, and can generate variable QR codes for full traceability from factory to pharmacy shelf.
Egg and Food Date Coding
In food production, freshness and safety depend on clear date marking. The 960 handles high-speed date coding on egg cartons, food packaging bags, and cardboard cases, keeping up with rapid conveyor speeds without compromising print clarity.
Carton and Packaging Lines
Logistics and packaging operations use the 960 to print batch codes, production dates, and QR codes on corrugated cartons — often replacing slower label applicators and reducing consumable costs.
Cable, Tube, and Pipe Production
Manufacturers of cables, pipes, and tubing use non-contact inkjet coding to mark meterage, batch numbers, and standards information along the length of extruded products.

Why Choose the Langdi 960 Over Alternatives?
Cost efficiency: Non-contact inkjet printing uses no labels and no pre-printed plates, so per-code costs stay low and changeovers are instant.
Flexibility: A single unit can be redeployed across multiple production lines and product types, making it ideal for factories with varied SKUs.
Traceability: Support for variable QR codes means every unit can carry a unique, scannable identity — a core requirement in pharma, food, and regulated manufacturing.
Compact footprint: At 21 kg, the 960 fits where bulkier coding systems cannot, and installation requires minimal disruption to existing lines.
Print quality: Crisp, permanent, high-contrast codes that remain readable throughout the product lifecycle and across storage and transport conditions.
How to Get the Most From Your Inkjet Coder
- Match ink to material: Confirm the ink type suits porous cartons versus non-porous plastics and coated surfaces.
- Position the print head correctly: Maintain a consistent print distance for sharp, distortion-free codes on moving products.
- Test variable data workflows: Verify that your ERP or line software can push changing QR code data to the printer in real time.
- Schedule routine maintenance: Clean the print head regularly and follow the manufacturer's service intervals for long-term reliability.
Final Thoughts
The Langdi 960 high-speed industrial inkjet printer is a practical, versatile, and space-efficient coding solution for manufacturers who need dependable date, batch, and variable QR code printing across a wide range of materials. Its compact 21 kg build, fully automatic operation, and multi-industry compatibility make it a strong fit for food, beverage, pharmaceutical, cosmetics, electronics, and automotive producers alike.
If your production line needs faster, more flexible, and more traceable coding — without the recurring cost of labels — the Langdi 960 is worth a closer look.
