70μm Bright Silver BOPP Film (surface metallised) Beverage & Dairy Bottles Label Material — FP7531

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
• PP film face — balanced stiffness and weather resistance

FAQ

Would the 62g White Glassine liner on FP7531 (70μm Bright Silver BOPP Film (surface metallised), Hot Melt) change how it grips PET and glass beverage bottles, and what would you send as a sample?

70μm Bright Silver BOPP Film (surface metallised) is specified for the beverage & dairy bottles field, which does not mean every substrate in it. BOPP film resists moisture and flexes with a squeezable wall instead of cracking. Where the surface is recycled or carries mould release, treat the first roll as a trial.

At what temperature do we apply FP7531 (70μm Bright Silver BOPP Film (surface metallised), Hot Melt), and what can it take afterwards, 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 FP7531 (70μm Bright Silver BOPP Film (surface metallised)), what tack and peel should we expect from Hot Melt adhesive at 23 °C, 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.

Can we start with less than a full run of FP7531 (70μm Bright Silver BOPP Film (surface metallised), Hot Melt), 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.

Is F41771 a drop-in alternative to FP7531 (70μm Bright Silver BOPP Film (surface metallised)), and which holds better at the edge?

FP7531 runs Hot Melt adhesive on 62g White Glassine Liner, while F41771 runs Standard on 62g White Glassine 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.
