Paper, 100 gsm — FL0102W21

What this construction is

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 water-based 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.

When to choose something else

Immersion and wash-off

Prolonged water contact sits outside the design envelope of a standard water-based acrylic.

Very oily substrates

Oil on the surface prevents the adhesive from wetting out; test before running production.

Wet or chilled environments

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.

How FL0102W21 sits inside the Self Adhesive Paper series

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.
