Durable packaging for greasy and moist products. Duplex paper is a laminated food-grade paper composed of a friction-bonded cellulose sheet and a polyethylene (PE) film, giving it excellent resistance to moisture and grease. Widely used by butchers, delicatessens, cheesemongers, and fishmongers, it is ideal for packaging meats, cheeses, fish, or fatty preparations. Flexible, opaque, and hygienic, duplex paper ensures optimal food protection while preserving freshness and preventing liquid transfer. Available in several sizes, it easily adapts to all professional counters.
