70g Top-coated Thermal Paper Express & Logistics Waybills Label Material — S2A551

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

FAQ

What does S2A551 (70g Top-coated Thermal Paper, All-weather Low-temperature) on a 50g White Glassine liner need on corrugated cartons and waybill stock: primer, corona, or nothing, and how do we check that before a full run?

70g 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.

How cold can the line run before the All-weather Low-temperature adhesive on S2A551 (70g Top-coated Thermal Paper) stops grabbing, and how do we verify it on the line?

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.

Which standard are the tack and peel values for 70g Top-coated Thermal Paper on 50g White Glassine reported to, and how do we reproduce the test?

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 many square metres of S2A551 in 70g Top-coated Thermal Paper makes a minimum run, 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.

What is the difference between S2A551 (70g Top-coated Thermal Paper) and SR0041, and can we get both as samples?

S2A551 runs All-weather Low-temperature adhesive on 50g 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.
