FAQ

We print 70g Premium Woodfree Paper on 58g White CCK — will that hold on paper, card and file folders, and which document states that?

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 W150KC (70g Premium Woodfree Paper, Medium-tack) on 58g White CCK hold its service range after a week at 60 °C, and how do we verify it on the line?

The minimum application temperature is 10 °C and the service range after labelling is -10–85 °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.

Which standard are the tack and peel values for 70g Premium Woodfree Paper on 58g White CCK reported to, and which document states it?

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.

How long from purchase order to shipment on W150KC (70g Premium Woodfree Paper, Medium-tack) with a 58g White CCK liner, and can a trial roll count towards 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.

We used W4MG31 before. What changes if we switch to W150KC (70g Premium Woodfree Paper), and which holds better at the edge?

W150KC runs Medium-tack adhesive on 58g 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.
