FAQ

Is Medium-tack adhesive on W12101 (70g Premium Woodfree Paper) enough for paper, card and file folders, or do we need higher tack, and does the liner change the answer?

70g Premium Woodfree Paper is specified for the office & stationery 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.

Is there a storage limit on W12101 (70g Premium Woodfree Paper, Medium-tack) once it sits on a 62g White Glassine liner, and does the liner shift 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.

What are the initial tack and 90° peel figures for W12101 (70g Premium Woodfree Paper, Medium-tack), and which document states it?

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 W12101 in 70g Premium Woodfree 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.

Both look like the same face stock, so why pick W12101 (70g Premium Woodfree Paper) over W4MG31, and is one a drop-in for the other?

W12101 runs Medium-tack adhesive on 62g 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.
