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

We used a generic 70g Premium Woodfree Paper before and it lifted — is W1HK10 any different on paper, card and file folders, and how do we check that before a full run?

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.

Does W1HK10 (70g Premium Woodfree Paper, Medium-tack) on 80g White CCK hold its service range after a week at 60 °C, and what happens at the low end?

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.

Do the ≥6 N/25 mm peel figures for W1HK10 (70g Premium Woodfree Paper, Medium-tack) come from a 20 min dwell, and is that a 20 min or 24 h value?

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 W1HK10 (70g Premium Woodfree Paper, Medium-tack) start at on a 80g White CCK liner, and does a trial roll count, and is export packing included?

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 W1HK10 (70g Premium Woodfree Paper) over W4MG31, and can we get both as samples?

W1HK10 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.
