72g Economy Top-coated Thermal Paper Express & Logistics Waybills Label Material — S3MG31

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

Where does S3MG31 (72g Economy Top-coated Thermal Paper, Hot Melt) fail first on corrugated cartons and waybill stock, and does the liner change the answer?

72g 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. Not recommended for PVC surfaces; small diameters, irregular or squeezable bottles.

Is S3MG31 (72g Economy Top-coated Thermal Paper, Hot Melt) rated for a cold store, and down to what temperature, and is there a written figure for it?

The minimum application temperature is 10 °C and the service range after labelling is -15–65 °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.

Is ≥7 N/25 mm the peel for S3MG31 (72g Economy Top-coated Thermal Paper, Hot Melt) after 20 min or after 24 h, and what substrate was it measured on?

Initial tack is ≥14 N by the ball method and 90° peel is ≥7 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.

Does the 62g White Glassine liner add lead time to a S3MG31 (72g Economy Top-coated Thermal Paper, Hot Melt) order, and can it be pooled with other codes?

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 S3MG31 (72g Economy Top-coated Thermal Paper) and SR0041, and which holds better at the edge?

S3MG31 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.
