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.”
