72g Economy Top-coated Thermal Paper Express & Logistics Waybills Label Material — S3HG41

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

Where does S3HG41 (72g Economy Top-coated Thermal Paper, Medium-tack) fail first on corrugated cartons and waybill stock, and what would you send as a sample?

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. Where the surface is recycled or carries mould release, treat the first roll as a trial.

How cold can the line run before the Medium-tack adhesive on S3HG41 (72g Economy 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.

What are the initial tack and 90° peel figures for S3HG41 (72g Economy Top-coated Thermal Paper, Medium-tack), and does the liner change the figure?

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.

What is the minimum order quantity and lead time for S3HG41 (72g Economy Top-coated Thermal Paper, Medium-tack), 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 S3HG41 (72g Economy Top-coated Thermal Paper) and SR0041, and is one a drop-in for the other?

S3HG41 runs Medium-tack adhesive on Blue 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.
