FAQ

Where does W1MG30 (70g Premium Woodfree Paper, Hot Melt) fail first on paper, card and file folders, 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. Not recommended for PVC surfaces; small diameters, irregular or squeezable bottles.

Is W1MG30 (70g Premium Woodfree Paper, Hot Melt) rated for a cold store, and down to what temperature, and how do we verify it on the line?

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.

Which standard are the tack and peel values for 70g Premium Woodfree Paper on 60g White Glassine reported to, and does the liner change the figure?

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.

If we order W1MG30 in a slit roll of 70g Premium Woodfree Paper, what is the smallest quantity, and can it be pooled with other codes?

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 W1MG30 (70g Premium Woodfree Paper) and W4MG31, and can we get both as samples?

The adhesive is the same and the liner differs: W1MG30 uses 60g White Glassine 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.
