75μm Synthetic Paper Cold Chain & Fresh Food Label Material — F8LG31

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

• Synthetic paper face — water resistant, tear resistant, good stiffness
• Verified by customer mass production

FAQ

What substrates is F8LG31 (75μm Synthetic Paper) built for, given it runs a Freezer-grade adhesive, and how do we check that before a full run?

75μm Synthetic Paper is specified for the cold chain & fresh food 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.

Does the 62g White Glassine liner on F8LG31 (75μm Synthetic Paper, Freezer-grade) change how it behaves when applied cold, 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.

For F8LG31 (75μm Synthetic Paper), what tack and peel should we expect from Freezer-grade adhesive at 23 °C, and which document states it?

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.

Can we start with less than a full run of F8LG31 (75μm Synthetic Paper, Freezer-grade), and can a trial roll count towards 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.

What is the difference between F8LG31 (75μm Synthetic Paper) and F10050, and can we get both as samples?

F8LG31 runs Freezer-grade 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.
