MJ0802W21 is a 60mic 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 water-based permanent 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.

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.
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.
