76g Premium Top-coated Thermal Paper Express & Logistics Waybills Label Material — S2HG31

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

• Medium-tack adhesive system — balanced adhesion and converting performance
• Thermal paper face — direct thermal printing, no ribbon required

FAQ

What substrates is S2HG31 (76g Premium Top-coated Thermal Paper) built for, given it runs a Medium-tack adhesive, and what would you send as a sample?

76g Premium 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.

Does the 62g White Glassine liner on S2HG31 (76g Premium Top-coated Thermal Paper, Medium-tack) change how it behaves when applied cold, and is there a written figure for 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 S2HG31 (76g Premium Top-coated Thermal Paper), what tack and peel should we expect from Medium-tack adhesive at 23 °C, and what substrate was it measured on?

Initial tack is ≥14 N by the ball method and 90° peel is — N/25 mm after —. 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.

Is S2HG31 (76g Premium Top-coated Thermal Paper) kept in stock, or is it produced to order with Medium-tack adhesive, 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.

Is SR0041 a drop-in alternative to S2HG31 (76g Premium Top-coated Thermal Paper), and which one should we trial first?

S2HG31 runs Medium-tack 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.
