70μm Bright White PE Film HDPE Bottles Label Material — F37331

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
• PE film face — soft and conformable, ideal for squeezable bottles and curved surfaces

FAQ

We print 70μm Bright White PE Film on 62g White Glassine — will that hold on HDPE bottles and closures, and which document states that?

70μm Bright White PE Film is specified for the hdpe bottles field, which does not mean every substrate in it. PE film is soft and conforms to squeezable and curved bottles. Where the surface is recycled or carries mould release, treat the first roll as a trial.

At what temperature do we apply F37331 (70μm Bright White PE Film, Standard), and what can it take afterwards, 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.

How much tack does F37331 (70μm Bright White PE Film) have with Standard adhesive, measured to which standard, 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.

Does the 62g White Glassine liner add lead time to a F37331 (70μm Bright White PE Film, Standard) order, and is export packing included?

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.

Both look like the same face stock, so why pick F37331 (70μm Bright White PE Film) over B373T0, and which one should we trial first?

The adhesive is the same and the liner differs: F37331 uses 62g White Glassine Liner, while B373T0 uses 30μm Clear PET 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.
