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.

FAQ

Where does S20893 (70g Economy Top-coated Thermal Paper, Adhesive code confirmed per order (type not yet classified)) fail first on frozen cartons and chilled packs, and what would you send as a sample?

70g Economy Top-coated Thermal Paper is specified for the cold chain & fresh food 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.

Does the 58g Yellow Glassine liner on S20893 (70g Economy Top-coated Thermal Paper, Adhesive code confirmed per order (type not yet classified)) change how it behaves when applied cold, and how do we verify it on the line?

The minimum application temperature is -15 °C and the service range after labelling is -30–65 °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.

What do the 70g Economy Top-coated Thermal Paper and Adhesive code confirmed per order (type not yet classified) combination report for tack and peel, and which document states it?

Initial tack is ≥10 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.

What quantity does S20893 (70g Economy Top-coated Thermal Paper, Adhesive code confirmed per order (type not yet classified)) start at on a 58g Yellow Glassine liner, and does a trial roll count, and does a slit roll change it?

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.

Both look like the same face stock, so why pick S20893 (70g Economy Top-coated Thermal Paper) over SR0041, and does the price differ much?

S20893 runs Adhesive code confirmed per order (type not yet classified) adhesive on 58g Yellow 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.
