FL0401W21 is a 80mic white PE film on a 60gsm 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.

PE is a polyethylene film, softer and more conformable than PET or BOPP. That conformability is the whole point: it wraps squeezable bottles and curved surfaces without lifting at the edges, and it moves with the container instead of fighting it.
Underneath it sits removable. 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.

Retail and FMCG work where the label has to come off again without taking the print with it. The construction is built so the adhesive releases from the liner cleanly and re-seats on the pack, which keeps short promotional cycles and price corrections out of the scrap bin.
When a brand wants to see the finished pack before committing to a print run, removable stock lets the same bottle, carton or device carry several label designs in a single day. Nothing is consumed except the label itself.
Reusable containers that travel between plant and customer pick up handling labels that must not leave a residue on the plastic. A removable construction keeps the asset clean across cycles and avoids the manual scraping step that eats labour on returnable pools.
Removable adhesives need a smooth, clean face to grip and release predictably. On fibrous recycled board or dusty substrates the label may lift at the edges before it is meant to.
Sun and heat let a removable adhesive creep. For anything that lives outdoors for months, a permanent system is the honest answer.
PE film is soft and conformable, which suits squeezable containers, but it moves more than PET under tension. Confirm the die-cutting and dispensing set-up.
The Self Adhesive PE Film series holds 4 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.
| Code | Facestock | Adhesive | Liner |
|---|---|---|---|
| FL0401W21 | 80mic white PE film | Removable | 60gsm white glassine liner |
| FL0402W21 | 80mic white PE film | Water-based acrylic adhesive | 60gsm white glassine liner |
| FL0403W21 | 80mic white PE film | Freezer-grade adhesive | 60gsm white glassine liner |
| FL0404W21 | 80mic white PE film | Hot-melt adhesive | 60gsm white glassine liner |
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.
