What it is
Duplex board is tough yet thin, and unlike corrugated board it takes a bright, clean printing surface. It is the usual material for cartons for small goods, from food to pharmaceuticals.
Multi-layer recycled board with a lighter top layer, used for folding cartons and printed packaging. It is part of Bollant’s Recycled Paper and Board family. Recovered paper and board from municipal and trade collection, graded before pulping. Plant-based additives are used for brightness.
Where it is used

- Mono cartons for FMCG and pharma

How it is made
Recovered paper is graded, de-inked and hydro-pulped, cleaned and refined, then formed, pressed and dried on automated, PLC-controlled paper machines. Reels are finished and cut to the order.
Limitations
Recycled fibre shortens each time it is reused, so strength-critical grades may need a share of long-fibre input. We do not claim paper can be recycled indefinitely.
