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

Can we apply W1HK11 (70g Premium Woodfree Paper, Medium-tack) to paper, card and file folders straight off the roll, and what would you send as a sample?

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.

W1HK11 (70g Premium Woodfree Paper, Medium-tack) in a 60 °C plant: what application window should we plan for, and is there a written figure for it?

The minimum application temperature is 10 °C and the service range after labelling is -10–80 °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.

Does W1HK11 (70g Premium Woodfree Paper, Medium-tack) really measure ≥13 N tack, and on which substrate, and how do we reproduce the test?

Initial tack is ≥13 N by the ball method and 90° peel is ≥6 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 W1HK11 (70g Premium Woodfree Paper, Medium-tack) start at on a 80g White CCK liner, and does a trial roll count, 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.

We used W4MG31 before. What changes if we switch to W1HK11 (70g Premium Woodfree Paper), and which holds better at the edge?

W1HK11 runs Medium-tack adhesive on 80g White CCK 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.
