SF577 Composite Thermal Paper Express & Logistics Waybills Label Material — S75721

Construction

The three functional layers of this item. Selecting on face stock alone is where most specification errors begin — the adhesive and liner decide how it behaves on your press.

Product features

• Standard water-based adhesive with stable, consistent performance
• Thermal paper face — direct thermal printing, no ribbon required
• Verified by customer mass production

FAQ

Does S75721 (SF577 Composite Thermal Paper) with Standard adhesive bond to corrugated cartons and waybill stock without a primer, and does it still hold on our own substrate?

SF577 Composite Thermal Paper is specified for the express & logistics waybills field, which does not mean every substrate in it. Direct thermal prints without a ribbon, but heat, sunlight and plasticiser contact keep developing the coating. Where the surface is recycled or carries mould release, treat the first roll as a trial.

What happens to S75721 (SF577 Composite Thermal Paper) below 60 °C with this Standard adhesive, and does the liner shift it?

The minimum application temperature is 10 °C and the service range after labelling is -10–70 °C. Below the minimum the adhesive cannot wet out, and edges lift within hours on a curved wall. Both figures are measured at 23±2 °C / 50±5 % RH, so confirm them with a trial roll on your line.

For S75721 (SF577 Composite Thermal Paper), what tack and peel should we expect from Standard adhesive at 23 °C, and how do we reproduce the test?

Initial tack is ≥8 N by the ball method and 90° peel is ≥6 N/25 mm after 20 min. Both are measured to FINAT FTM 9 and FTM 2 at 23±2 °C / 50±5 % RH. Peel grows with dwell, so compare the same hold time against your own pull test.

How many square metres of S75721 in SF577 Composite Thermal Paper makes a minimum run, and what starts the clock?

Minimum order quantity is 500 ㎡ and lead time is 15 days after artwork and roll-format approval. A trial roll for press approval can be arranged before the production run starts. Shipment is ex-works Guangzhou, and it can be consolidated with other codes on the same order.

We used SR0041 before. What changes if we switch to S75721 (SF577 Composite Thermal Paper), and does the price differ much?

S75721 runs Standard adhesive on 62g White Glassine Liner, while SR0041 runs Low-tack Removable on 62g White Glassine Liner. The difference is the adhesive chemistry, which decides edge lift and high-speed behaviour more than the face does. Compare the two technical tables above, then test both on the same substrate.
