FL0304W21 is a 60mic Glossy white PET film on a 80gsm white glassine liner, built for flexographic presses, in roll form. This page gives you the construction as we actually coat it, where it belongs, and what to pick instead when it does not.

PET is a polyester film, and it is specified where paper and BOPP run out of road: higher heat, tighter dimensional tolerance and a firmer, more premium feel. It is dimensionally stable through the press and through the applicator, which is why it holds register on small-format work such as cosmetic and electronics labelling.
Underneath it sits solvent acrylic adhesive. The liner is a glassine — a supercalendered paper with a dense, closed surface. Glassine releases cleanly at high converting speeds, it is the cheapest liner that does the job, and it is the default for roll-fed work.
This construction sits in the Flexo family, which we build for flexographic presses, in roll form. The family grouping is not marketing shorthand — it is how the topcoat is chosen.

Beverage lines mean water, ice and wash-down. A solvent acrylic system is chosen where the label has to hold through that, on glass and on PET bottles alike.
Small containers handled constantly, often stored in humid bathrooms. Solvent acrylic gives the grab and the durability that small-format cosmetic labelling depends on.
Where a label crosses a yard or sits on a pallet in the open for a few weeks, the solvent system is the more forgiving choice than a standard water-based one.
Solvent acrylic costs more than water-based. On a commodity label the premium buys nothing.
Where the adhesive odour has to be minimal, water-based is the easier specification.
PET costs more than a paper facestock. It earns that premium in heat resistance, dimensional stability and a premium feel — not on a commodity carton label.
The Self Adhesive PET Film series holds 8 constructions in our catalogue. They share the same facestock family, so the differences that matter are adhesive system and liner — and those two decide which jobs each code wins.

Buyers often ask the reverse question: the construction works, but the press changes. These are the codes in other families built on the same facestock type.
