FAQ

What does W1MP20 (70g Premium Woodfree Paper, Hot Melt) on a 80g Yellow PEK liner need on paper, card and file folders: primer, corona, or nothing, 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. Where the surface is recycled or carries mould release, treat the first roll as a trial.

W1MP20 (70g Premium Woodfree Paper, Hot Melt) in a 60 °C plant: what application window should we plan for, and what happens at the low end?

No application-temperature figure is released for this construction, and we will not invent one. Adhesive wet-out decides the low end, and that depends on your line speed and the temperature of the bottle. The declared test condition is 23±2 °C / 50±5 % RH, and a trial roll shows where your own line sits.

For W1MP20 (70g Premium Woodfree Paper), what tack and peel should we expect from Hot Melt adhesive at 23 °C, and is that a 20 min or 24 h value?

No tack or peel figure is released for this construction, so we will not quote one. We report tack to FINAT FTM 9 by the ball method and 90° peel to FTM 2, at 23±2 °C / 50±5 % RH.

If we order W1MP20 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.

How does W1MP20 (70g Premium Woodfree Paper) compare with W4MG31 on paper, card and file folders, and which one should we trial first?

The adhesive is the same and the liner differs: W1MP20 uses 80g Yellow PEK 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.
