MJ0201W21 is a 180gsm high-glossy cast coated paper on a 80gsm Glassine Liner, built for Memjet-based inkjet presses and print engines. 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 hot-melt 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 Memjet family, which we build for Memjet-based inkjet presses and print engines. The family grouping is not marketing shorthand — it is how the topcoat is chosen.

Hot-melt is the workhorse system for long runs: it wets out fast, runs at line speed and holds on the substrates that dominate volume labelling. This is the construction to quote when the job is cost-sensitive and the environment is ordinary.
Rough, slightly porous surfaces need an adhesive that flows into the profile instead of sitting on top of it. Hot-melt does that without a special primer.
Batch codes, ingredient panels, logistics barcodes — the everyday labels that carry no unusual environmental demand and simply have to be reliable and cheap.
Sustained heat and high humidity are the conditions where hot-melt systems need an evaluation before you commit a full run.
Surface contamination blocks wet-out. Wipe-down or a high-tack variant is the fix, not a thicker coat.
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.
Memjet engines fire a very wide page-width array at high speed, which puts two demands on the facestock that other inkjet platforms do not: the coating has to dry fast enough that the print can be rewound immediately, and it has to be uniform across the full width, because a page-width head shows up any variation as a band rather than as a small defect.
Constructions in this family are coated and finished for that profile. If you are running a Memjet engine and the print looks weak, the conversation is usually about the topcoat rather than the film.
The Matte Photo paper series holds 2 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 |
|---|---|---|---|
| MJ0201W21 | 180gsm high-glossy cast coated paper | Hot-melt adhesive | 80gsm Glassine Liner |
| MJ0202W21 | 80gsm semi-glossy cast coated paper | Water-based acrylic adhesive | 95gsm white paper |
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.
