90g Inkjet Woodfree Paper Digital Inkjet & Laser Label Material — W6MK10

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.

Product features

• Hot melt adhesive system — good heat resistance for demanding environments
• Woodfree paper face — good for writing and printing

FAQ

What does W6MK10 (90g Inkjet Woodfree Paper, Hot Melt) on a 80g White CCK liner need on laser and inkjet printed sheets: primer, corona, or nothing, and which document states that?

90g Inkjet Woodfree Paper is specified for the digital inkjet & laser 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 happens to W6MK10 (90g Inkjet Woodfree Paper) below 60 °C with this Hot Melt adhesive, 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.

What do the 90g Inkjet Woodfree Paper and Hot Melt combination report for tack and peel, and how do we reproduce the test?

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.

Do we have to take a full production lot of W6MK10 (90g Inkjet Woodfree Paper), or can Hot Melt codes be pooled, 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.

Both look like the same face stock, so why pick W6MK10 (90g Inkjet Woodfree Paper) over W4MG31, and which holds better at the edge?

The adhesive is the same and the liner differs: W6MK10 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.
