70μm Synthetic Paper General Standard Label Material — F7MG31

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
• Synthetic paper face — water resistant, tear resistant, good stiffness

FAQ

What substrates is F7MG31 (70μm Synthetic Paper) built for, given it runs a Hot Melt adhesive, and how do we check that before a full run?

70μm Synthetic Paper is specified for the general standard field, which does not mean every substrate in it. Synthetic paper prints like coated paper and survives water and tearing like a film. Where the surface is recycled or carries mould release, treat the first roll as a trial.

What service temperature range applies to F7MG31 (70μm Synthetic Paper) with Hot Melt adhesive, 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.

Do the peel figures for F7MG31 (70μm Synthetic Paper, Hot Melt) change with the 62g White Glassine liner, and what substrate was it measured on?

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.

How many square metres of F7MG31 in 70μm Synthetic Paper makes a minimum run, and does a slit roll change it?

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.

We used F10050 before. What changes if we switch to F7MG31 (70μm Synthetic Paper), and which holds better at the edge?

F7MG31 runs Hot Melt adhesive on 62g White Glassine Liner, while F10050 runs Low-odor / Residue-free on 36μm Clear PET Liner. The difference is the adhesive chemistry, which decides edge lift and high-speed behaviour more than the face does. Compare the two technical tables above, then test both on the same substrate.
