MJ0801W21 is a 36mic Pearl white BOPP film 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.

BOPP is a biaxially oriented polypropylene film. Orienting it in both directions is what gives the film its stiffness and its dimensional stability, so a thin BOPP label still lies flat on the pack and still feeds reliably at line speed. It is waterproof, it does not tear the way paper does, and it accepts a topcoat that lets UV and water-based inks key to the surface instead of sitting on it.
Underneath it sits solvent 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 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.

Beverage lines mean water, ice and wash-down. A solvent acrylic system is chosen where the label has to hold through that, on glass and on PET bottles alike.
Small containers handled constantly, often stored in humid bathrooms. Solvent acrylic gives the grab and the durability that small-format cosmetic labelling depends on.
Where a label crosses a yard or sits on a pallet in the open for a few weeks, the solvent system is the more forgiving choice than a standard water-based one.
Solvent acrylic costs more than water-based. On a commodity label the premium buys nothing.
Where the adhesive odour has to be minimal, water-based is the easier specification.
BOPP does not absorb ink the way paper does. The press needs its tension, heat and ink settings confirmed for film before the first production run.
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 Pearl White PP series holds 3 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.
