LJ0101W21 is a 140gsm semi-glossy cast coated paper on a 95gsm white liner, built for laser and LED sheet printers. 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 water-based acrylic adhesive. The liner is a paper grade, specified for release and for runnability rather than for printability. The exact grade is on the data sheet.
This construction sits in the Laserjet family, which we build for laser and LED sheet printers. The family grouping is not marketing shorthand — it is how the topcoat is chosen.

A water-based acrylic system is the default when the job does not call for anything exotic: it prints well, converts cleanly and keeps the odour profile low compared with solvent systems.
Where the printed label sits close to the consumer, or the converter runs a tight plant with limited extraction, a water-based adhesive is usually the easier conversation with the customer.
One adhesive system across a paper and a film facestock keeps a multi-SKU programme simple to specify, stock and convert.
Prolonged water contact sits outside the design envelope of a standard water-based acrylic.
Oil on the surface prevents the adhesive from wetting out; test before running production.
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 Semi-gloss paper series holds 1 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 |

| LJ0101W21 | 140gsm semi-glossy cast coated paper | Water-based acrylic adhesive | 95gsm white 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.
