70g Economy Top-coated Thermal Paper Express & Logistics Waybills Label Material — S31131

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

• Hot melt adhesive system — good heat resistance for demanding environments
• Thermal paper face — direct thermal printing, no ribbon required

FAQ

Is Hot Melt adhesive on S31131 (70g Economy Top-coated Thermal Paper) enough for corrugated cartons and waybill stock, or do we need higher tack, and which document states that?

70g Economy Top-coated 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.

We fill at 60 °C — will S31131 (70g Economy Top-coated Thermal Paper, Hot Melt) still wet out, and does the liner shift it?

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 do the 70g Economy Top-coated Thermal Paper and Hot Melt combination report for tack and peel, and what substrate was it measured on?

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.

How much S31131 (70g Economy Top-coated Thermal Paper, Hot Melt) on a 62g White Glassine liner do we have to order, and how long does it take, and does a slit roll change 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.

Both look like the same face stock, so why pick S31131 (70g Economy Top-coated Thermal Paper) over SR0041, and is one a drop-in for the other?

S31131 runs Hot Melt 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.
