50μm Bright Silver BOPP Film (inner metallised) Detergent & Daily Chemical Bottles Label Material — FL6430

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
• PP film face — balanced stiffness and weather resistance

FAQ

FL6430 (50μm Bright Silver BOPP Film (inner metallised)): does the Standard adhesive on 30μm Clear PET give enough grab at the HDPE and squeezable detergent bottles edge, and does the liner change the answer?

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. Not recommended for irregular curves, soft bottles.

At what temperature do we apply FL6430 (50μm Bright Silver BOPP Film (inner metallised), Standard), and what can it take afterwards, and how do we verify it on the line?

The minimum application temperature is 10 °C and the service range after labelling is -10–80 °C. Below the minimum the adhesive cannot wet out, and edges lift within hours on a curved wall. Both figures are measured at 23±2 °C / 50±5 % RH, so confirm them with a trial roll on your line.

How much tack does FL6430 (50μm Bright Silver BOPP Film (inner metallised)) have with Standard adhesive, measured to which standard, and what substrate was it measured on?

Initial tack is ≥8 N by the ball method and 90° peel is ≥4.5 N/25 mm after 20 min. Both are measured to FINAT FTM 9 and FTM 2 at 23±2 °C / 50±5 % RH. Peel grows with dwell, so compare the same hold time against your own pull test.

How much FL6430 (50μm Bright Silver BOPP Film (inner metallised), Standard) on a 30μm Clear PET liner do we have to order, and how long does it take, 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 FL6430 (50μm Bright Silver BOPP Film (inner metallised)), and can we get both as samples?

The adhesive is the same and the liner differs: FL6430 uses 30μm Clear PET Liner, while F41771 uses 62g White Glassine Liner. Changing the liner shifts release force and die-cutting behaviour, and the price moves with it. Compare the two technical tables above, then test both on the same substrate.
