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

Is 70g Premium Woodfree Paper the right face for paper, card and file folders, or do we need a film instead, 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.

What is the minimum application temperature for W1MG31 (70g Premium Woodfree Paper, Hot Melt) on a 62g White Glassine liner, 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.

For W1MG31 (70g Premium Woodfree Paper), what tack and peel should we expect from Hot Melt adhesive at 23 °C, 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 much W1MG31 (70g Premium Woodfree Paper, Hot Melt) on a 62g White Glassine liner do we have to order, and how long does it take, 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.

Both look like the same face stock, so why pick W1MG31 (70g Premium Woodfree Paper) over W4MG31, and which one should we trial first?

Both share the adhesive and liner and differ in the face: 70g Premium Woodfree Paper against 100g Premium Woodfree Paper. The weight and calliper change stiffness, die-cutting behaviour and price. Compare the two technical tables above, then test both on the same substrate.
