JYZN-T3255-Thermal Transfer Overprinter

The Thermal Transfer Overprinter is a digital coding solution designed specifically for flexible packaging. It uses heat and pressure to transfer ink from a ribbon onto packaging materials, producing high‑resolution (300dpi), crisp, and durable prints of variable data such as production dates, batch numbers, barcodes, and QR codes.

In one sentence: A professional printer for flexible packaging that delivers clear, scannable, and long‑lasting codes.

Key Advantages:

  • ✅ 300dpi high resolution – prints are sharp and scan‑friendly

  • ✅ Vacuum bag‑flattening – holds bags flat for perfectly aligned prints every time

  • ✅ 32×55mm large print area – covers most packaging label needs in one pass

  • ✅ Up to 600m ribbon capacity – fewer changeovers for continuous production

  • ✅ Industrial PC control – edit and save templates on a touchscreen, no external computer needed

  • ✅ RS‑232 interface – seamless integration with PLCs and production line systems

  • ✅ Adjustable print speed – 50‑600mm/s to match your production pace

Print Speed: 50 – 600mm/s (adjustable)

Applicable Materials: Plastic films, laminated films, coated paper, and other flexible packaging materials.

Applicable Industries: Food, pharmaceuticals, personal care, electronics, hardware components, and any industry using flexible packaging.

What It Prints: Production dates, expiration dates, batch numbers, serial numbers, barcodes (Code128, EAN, etc.), QR codes, Data Matrix codes, logos, and graphics.


In one sentence: Thermal Transfer Overprinter = The professional tool for printing clear, durable, and scannable codes onto flexible packaging – giving every bag a reliable “ID card.”
