50μm Bright White PET Film Cold Chain & Fresh Food Label Material — D57631

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

• PET film face — dimensional stability and good heat resistance

FAQ

Can we apply D57631 (50μm Bright White PET Film, Low-temperature) to frozen cartons and chilled packs straight off the roll, and what would you send as a sample?

50μm Bright White PET Film is specified for the cold chain & fresh food field, which does not mean every substrate in it. PET film holds its dimensions and stiffness at higher temperatures than PP or PE. Where the surface is recycled or carries mould release, treat the first roll as a trial.

If our line runs at -18 °C, does D57631 (50μm Bright White PET Film, Low-temperature) need a slower speed to wet out, 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.

Can you give tack and peel for D57631 (50μm Bright White PET Film, Low-temperature) in N rather than a vague high-tack claim, and how do we reproduce the test?

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.

What quantity does D57631 (50μm Bright White PET Film, Low-temperature) start at on a 62g White Glassine liner, and does a trial roll count, 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.

What is the difference between D57631 (50μm Bright White PET Film) and D3CG71, and does the price differ much?

D57631 runs Low-temperature adhesive on 62g White Glassine Liner, while D3CG71 runs General-purpose on 80g 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.
