50μm Bright Silver BOPP Film (inner metallised) Detergent & Daily Chemical Bottles Label Material — FL5731

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

• Medium-tack adhesive system — balanced adhesion and converting performance
• PP film face — balanced stiffness and weather resistance

FAQ

Would the 62g White Glassine liner on FL5731 (50μm Bright Silver BOPP Film (inner metallised), Medium-tack) change how it grips HDPE and squeezable detergent bottles, and what would you send as a sample?

50μm Bright Silver BOPP Film (inner metallised) is specified for the detergent & daily chemical 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.

Does FL5731 (50μm Bright Silver BOPP Film (inner metallised), Medium-tack) on 62g White Glassine hold its service range after a week at 60 °C, 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 FL5731 (50μm Bright Silver BOPP Film (inner metallised), Medium-tack), 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.

If we order FL5731 in a slit roll of 50μm Bright Silver BOPP Film (inner metallised), what is the smallest quantity, 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 F41771 a drop-in alternative to FL5731 (50μm Bright Silver BOPP Film (inner metallised)), and does the price differ much?

FL5731 runs Medium-tack 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.
