SF537 Composite Thermal Paper Express & Logistics Waybills Label Material — S75921

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

FAQ

Is SF537 Composite Thermal Paper the right face for corrugated cartons and waybill stock, or do we need a film instead, and does it still hold on our own substrate?

SF537 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 is the minimum application temperature for S75921 (SF537 Composite Thermal Paper, Standard) on a 62g White Glassine liner, and what happens at the low end?

No application-temperature figure is released for this construction, and we will not invent one. Adhesive wet-out decides the low end, and that depends on your line speed and the temperature of the bottle. The declared test condition is 23±2 °C / 50±5 % RH, and a trial roll shows where your own line sits.

What are the initial tack and 90° peel figures for S75921 (SF537 Composite Thermal Paper, Standard), and which document states it?

No tack or peel figure is released for this construction, so we will not quote one. We report tack to FINAT FTM 9 by the ball method and 90° peel to FTM 2, at 23±2 °C / 50±5 % RH.

What is the smallest order you will accept for S75921 (SF537 Composite Thermal Paper, Standard) on 62g White Glassine, and can a trial roll count towards it?

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.

What is the difference between S75921 (SF537 Composite Thermal Paper) and SR0041, and which holds better at the edge?

S75921 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.
