FAQ

Does W1MK60 (70g Premium Woodfree Paper) with Hot Melt adhesive bond to paper, card and file folders without a primer, 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. Not recommended for PVC surfaces; small diameters, irregular or squeezable bottles.

At what temperature do we apply W1MK60 (70g Premium Woodfree Paper, Hot Melt), and what can it take afterwards, and is there a written figure for it?

The minimum application temperature is 10 °C and the service range after labelling is -15–65 °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.

How much tack does W1MK60 (70g Premium Woodfree Paper) have with Hot Melt adhesive, measured to which standard, and which document states it?

Initial tack is ≥14 N by the ball method and 90° peel is ≥7 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 many square metres of W1MK60 in 70g Premium Woodfree Paper makes a minimum run, 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.

What is the difference between W1MK60 (70g Premium Woodfree Paper) and W4MG31, and can we get both as samples?

The adhesive is the same and the liner differs: W1MK60 uses 80g White CCK Liner, while W4MG31 uses 62g White Glassine Liner. Changing the liner shifts release force and die-cutting behaviour, and the price moves with it. Compare the two technical tables above, then test both on the same substrate.
