TTO printers for VFFS machines and flexible film
Add high-quality thermal transfer overprinting to vertical form-fill-seal lines, bags, pouches and flexible packaging films.
Application guidance for vffs coding printers.
How to specify this coding application
VFFS machinery normally needs a coder that prints reliably onto film before the pack is formed and sealed. Thermal transfer overprinters are designed for this kind of flexible packaging environment and can print dates, batch numbers, logos, barcodes and QR codes with strong clarity.
- Intermittent and continuous TTO mode selection
- Date, batch, barcode, QR code and logo printing
- Print area checks for film design and sealing position
- Ribbon width and ribbon saving considerations
- Trigger, encoder and machine interface checks
- Operator access for cassette and message changes
Recommended coding routes
Use these routes as a starting point before confirming samples, speed, substrate and integration details.
Intermittent VFFS machines
TTO can print during the indexed dwell when the packaging film stops briefly.
Continuous VFFS machines
Continuous-mode TTO follows film movement and can support higher-speed applications.
High-quality traceability
Thermal transfer is usually preferred where machine-readable codes or dense text must remain clear.

VFFS coding printers FAQs
Why use TTO on a VFFS machine?
TTO is well suited to printing variable data onto flexible film before forming and sealing, with high print quality and good ribbon control.
Can TTO print in continuous mode?
The T30 and T50 style range includes intermittent and continuous operation options depending on the model and application.
What can be printed on VFFS film?
Dates, batch numbers, shift codes, serial data, logos, barcodes, QR codes and nutrition-table style data may be possible.
What is needed for integration?
The film path, available mounting space, print window, speed, trigger signal and air supply should be confirmed.
