54μm Synthetic Paper Pharmaceutical Containers Label Material — F91981

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

• Standard water-based adhesive with stable, consistent performance
• Synthetic paper face — water resistant, tear resistant, good stiffness

FAQ

Is 54μm Synthetic Paper the right face for small-diameter vials and ampoule cartons, or do we need a film instead, and how do we check that before a full run?

54μm Synthetic Paper is specified for the pharmaceutical containers 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.

Is there a storage limit on F91981 (54μm Synthetic Paper, Standard) once it sits on a 80g White Glassine liner, and does that hold at our line temperature?

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.

What are the initial tack and 90° peel figures for F91981 (54μm Synthetic Paper, Standard), and does the liner change the figure?

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.

Does the 80g White Glassine liner add lead time to a F91981 (54μm Synthetic Paper, Standard) order, 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.

Is F10050 a drop-in alternative to F91981 (54μm Synthetic Paper), and which holds better at the edge?

F91981 runs Standard adhesive on 80g 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.
