FL0105W21 is a 70gsm semi-glossy cast coated paper on a 54gsm 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.

A paper facestock is the default for the great majority of label work. It takes ink readily, die-cuts predictably and keeps the cost of the finished label down. What varies between paper grades is the surface: a cast-coated sheet gives a smooth, high-gloss print face, a woodfree sheet gives a more absorbent matte face, and a thermal topcoat gives a heat-sensitive imaging layer instead of a printable one.
Underneath it sits freezer-grade 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.

Applied before the product goes down to temperature, the adhesive has to stay put while the pack contracts and while condensation forms on the surface. This is the construction we supply for that first cold contact.
Cartons that go from a cold store into a display freezer and back again see repeated temperature swings. The freezer-grade system is chosen for that cycle rather than for ambient shelf work.
Shipping and traceability labels applied at the cold store exit, onto surfaces that are already below ambient and often damp. Standard permanent adhesive is the wrong tool here.
The freezer-grade system is specified for cold application and cold service. Using it on ordinary ambient labelling adds cost for no benefit.
This is a permanent cold-chain adhesive, not a repositionable one. If the label has to move, look at the removable range instead.
Paper facestock is not waterproof. Where the label meets water, condensation or a wash-down, a film facestock — or a laminate over the print — is the correct answer.
The Self Adhesive Paper 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.
