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.

• Woodfree paper face — good for writing and printing

FAQ

Can we apply W1SG91 (70g Premium Woodfree Paper, Medium-tack) to corrugated cartons and waybill stock straight off the roll, and does it still hold on our own substrate?

70g Premium Woodfree Paper is specified for the express & logistics waybills field, which does not mean every substrate in it. Uncoated woodfree takes pen and stamp, and it is the least water-resistant face in the range. Where the surface is recycled or carries mould release, treat the first roll as a trial.

Can W1SG91 (70g Premium Woodfree Paper, Medium-tack) be applied at 60 °C on the line, and is there a written figure for it?

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.

Can you give tack and peel for W1SG91 (70g Premium Woodfree Paper, Medium-tack) in N rather than a vague high-tack claim, 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.

W1SG91 (70g Premium Woodfree Paper, Medium-tack): what is the shortest lead time you can hold to, and at what quantity, 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.

What is the difference between W1SG91 (70g Premium Woodfree Paper) and W4MG31, and which holds better at the edge?

W1SG91 runs Medium-tack adhesive on Double-layer White Glassine Liner, while W4MG31 runs Hot Melt 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.
