LANGDI 960 Industrial High-Speed Inkjet Printer: Reliable Variable QR Code and Date Coding for Modern Production Lines
In fast-moving manufacturing environments, coding is no longer a routine end-of-line task — it is a compliance requirement, a traceability tool, and a brand-protection measure. The LANGDI 960 industrial fully automatic high-speed inkjet printer is built for producers who need crisp, legible codes at production speed, whether they are stamping expiry dates on eggs, printing variable QR codes on pharmaceutical cartons, or marking batch numbers on cable and pipe. With a compact 21 kg body and a versatile ink system, the 960 model delivers continuous, high-resolution coding across food and beverage, cosmetics, electronics, pharmaceuticals, and auto-parts operations.
One Printer, Multiple Coding Jobs
The LANGDI 960 is a single-unit solution for both date coding and variable data inkjet printing. It handles fixed text, lot numbers, production dates, shelf-life information, barcodes, and dynamic QR codes without requiring a separate labeling station or pre-printed packaging. That flexibility makes it particularly valuable for factories running short runs, frequent SKU changes, or multi-language export packaging.
Key Functions and Capabilities
- Coding and inkjet printing in one platform — switch between simple date stamps and dynamic variable data without changing equipment.
- Variable QR code generation — supports serialized, one-per-item codes for anti-counterfeiting, promotions, traceability, and regulatory compliance.
- High-speed continuous operation — engineered to keep pace with automatic filling, boxing, and conveying lines rather than slowing them down.
- High-contrast, high-resolution output — dense character and matrix codes remain machine-readable on porous and non-porous surfaces alike.
- Compact 21 kg chassis — easy to install on existing lines, relocate between production rooms, or mount on a mobile stand.
Industries Served
Food and Beverage
The 960 is widely used for printing production and expiry dates on packaging bags, cartons, and bottles. Its ability to code eggs directly makes it a practical choice for poultry and dairy operations that must comply with shell-egg date marking regulations.
Pharmaceutical and Medical Packaging
Pharma manufacturers use the printer for batch numbers, expiry dates, and variable QR codes that link to serialization and track-and-trace systems. Codes stay sharp on medical packaging films, cartons, and blister sleeves.
Cosmetics and Personal Care
Cosmetic producers apply lot codes, manufacturing dates, and promotional QR codes on tubes, bottles, and folding cartons — ideal for short-run product launches and limited editions.
Electronics and Auto Parts
Electronic components and automotive parts benefit from permanent, smudge-resistant marking of part numbers, production dates, and traceability codes on packaging and small components.
Compatible Substrates and Materials
With the right ink selection, the LANGDI 960 prints reliably on a broad range of surfaces:
| Material Category | Typical Applications |
|---|---|
| Corrugated cartons and cardboard boxes | Outer shipping cartons, batch and date codes |
| Packaging bags and pouches | Food bags, stand-up pouches, sachets |
| Chemical and industrial bags | Fertilizer, resin, and powder packaging |
| Pharmaceutical packaging | Cartons, labels, foil and film |
| Coated paper (copperplate) and kraft paper | Premium cartons, kraft bags, retail packaging |
| Pipes and tubes | Diameter and batch marking on extruded products |
| Cables and wire | Meter marking, model codes, production dates |

Why Manufacturers Choose the LANGDI 960
Traceability without added complexity. Variable QR codes can be generated and printed inline, giving each unit a unique digital identity for recalls, warranty tracking, or consumer engagement campaigns.
Compliance-ready date marking. Clear, permanent dates reduce the risk of mislabeling and support regulatory inspection readiness, from shell eggs to medicines.
Compact and production-floor friendly. At 21 kg, the unit installs quickly on existing conveyors and can be repositioned as line layouts change — no heavy infrastructure or dedicated room required.
Broad material compatibility. One printer covers paper, cardboard, film, metal-adjacent packaging, and extruded products, reducing the number of coding devices a plant must maintain.
High-speed, continuous performance. Designed for automatic lines that run through long shifts, keeping throughput stable while codes remain accurate and legible.
Frequently Asked Questions
Can the LANGDI 960 print variable QR codes that change for every item?
Yes. The printer supports dynamic variable data, allowing a unique QR code or serial number to be generated for each product or carton in the run.
Is it suitable for coding eggshells?
Yes. Egg date coding is one of the most common applications, alongside food packaging, cartons, and pharmaceutical packaging.
What materials can it print on?
Common substrates include corrugated cartons, packaging bags, chemical bags, pharmaceutical packaging, copperplate paper, and kraft bags, as well as pipes, cables, and electronic components.
How much space does it require on the line?
The unit weighs just 21 kg, making it easy to mount, integrate, or relocate without major structural changes to your production setup.
