70g Top-coated Thermal Paper Hot Cups & High-Temperature Label Material — S14041

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

Would the 40g White Glassine liner on S14041 (70g Top-coated Thermal Paper, Hot Melt) change how it grips paper cups and hot-fill containers, and how do we check that before a full run?

70g Top-coated Thermal Paper is specified for the hot cups & high-temperature 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.

Can S14041 (70g Top-coated Thermal Paper, Hot Melt) be applied at 85 °C on the line, and how do we verify it on the line?

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 the peel value on S14041 (70g Top-coated Thermal Paper, Hot Melt) measured at 20 min dwell, and what substrate was it measured on?

Initial tack is ≥10 N by the ball method and 90° peel is ≥5 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.

If we order S14041 in a slit roll of 70g Top-coated Thermal Paper, what is the smallest quantity, 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 S14041 (70g Top-coated Thermal Paper), and which holds better at the edge?

S14041 runs Hot Melt adhesive on 40g 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.
