LJ0301W21 is a 75mic Pearl white BOPP film on a 135gsm 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.

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 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.
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.
The Pearl White PP 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.

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.
