50μm Clear BOPP Film Office & Stationery Label Material — F4MK11

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

F4MK11 (50μm Clear BOPP Film): does the Hot Melt adhesive on 80g White CCK give enough grab at the paper, card and file folders edge, and how do we check that before a full run?

50μm Clear BOPP Film is specified for the office & stationery 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 F4MK11 (50μm Clear BOPP Film) survive 60 °C in service, given the Hot Melt adhesive, and is there a written figure for it?

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 do the 50μm Clear BOPP Film and Hot Melt combination report for tack and peel, and is that a 20 min or 24 h value?

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.

How many square metres of F4MK11 in 50μm Clear BOPP Film makes a minimum run, 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.

How does F4MK11 (50μm Clear BOPP Film) compare with F41771 on paper, card and file folders, and is one a drop-in for the other?

F4MK11 runs Hot Melt adhesive on 80g White CCK 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.
