Haiwang supplies corrugated cardboard sheets in A, B, C and E flutes and 3-, 4- and 5-layer board, cut to your size on our 2,800 mm Marquip corrugator. Order plain sheets for your own box plant, pallet layer pads, or printed sheets ready to convert. We make 300,000 m² of board a day and ship flat from our factory near Qingdao Port.
A, B, C and E flutes in 3-, 4- and 5-layer board, for every corrugated carton sheet you convert.
Our Marquip line runs board up to 2,800 mm wide, for oversized boxes and large sheets.
Flat corrugated pads cut to your pallet size, to separate and protect layers of goods.
Escade anti-warp control and in-line quality monitoring keep every sheet flat and to spec.
We are a corrugated board producer first. Two lines make our corrugated board: a 2,800 mm Marquip line with Escade anti-warp control and in-line quality monitoring, and a 2,200 mm line running at up to 350 m/min. Both are built for short orders and frequent changeovers, so we run small trial orders and large volumes alike.
A smart logistics system moves board automatically from the corrugator to storage and dispatch, and our own fleet of 70 trucks handles delivery. We are FSC certified and run ISO 9001 quality management. Want finished boxes instead? See our printed boxes and dividers.
We reply within 24 hours.
