76g Premium Top-coated Thermal Paper Industrial Rough Surfaces Label Material — S2RG31

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

• Thermal paper face — direct thermal printing, no ribbon required
• Verified by customer mass production

FAQ

We used a generic 76g Premium Top-coated Thermal Paper before and it lifted — is S2RG31 any different on rough, dusty or low-energy parts, and how do we check that before a full run?

76g Premium Top-coated Thermal Paper is specified for the industrial rough surfaces 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 curved substrates (strong reaction with removable adhesive); above 70 °C, PMMA/PVC/PET/PP surfaces.

We fill at 60 °C — will S2RG31 (76g Premium Top-coated Thermal Paper, Removable) still wet out, and what happens at the low end?

The minimum application temperature is 10 °C and the service range after labelling is -20–70 °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.

Where does the S2RG31 (76g Premium Top-coated Thermal Paper, Removable) data sheet state its peel condition on a 62g White Glassine liner, and what substrate was it measured on?

Initial tack is 4–9 N by the ball method and 90° peel is 1–3.5 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.

What is the smallest order you will accept for S2RG31 (76g Premium Top-coated Thermal Paper, Removable) on 62g White Glassine, and is export packing included?

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.

How does S2RG31 (76g Premium Top-coated Thermal Paper) compare with SR0041 on rough, dusty or low-energy parts, and which one should we trial first?

S2RG31 runs Removable 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.
