CHINA UV PAPER

The main pulping and papermaking equipment is sourced from world-class suppliers including Kadant, Honeywell, Voith and Kadant Johnson, with the wastewater treatment station engineered by Xi'an Longhua Environmental Technology.

The full line runs on a DCS distributed control system interlocked with a QCS quality management system: key process parameters are sampled and adjusted in real time, and pulping, screening, cleaning and refining sections operate in closed loops — guaranteeing formation and stability at source.

Semi-glossy Art Paper process: a two-coat / one-press route using air-knife or blade coaters applies 18–22 g/m² per side, with a scientifically balanced clay–CaCO₃ pigment system; after soft-nip calendering the sheet reaches printing gloss ≥63% (matt grades 32–35%), Bekk smoothness ≥600 s and IGT surface strength suited to four-colour offset wet-on-wet printing, across 80–350 g/m².

Cast Coated Paper process: a cast-drum finishing step freezes the coating against a heated chrome drum and releases it as a mirror finish — 75° gloss ≥85 and PPS roughness ≤1.2 μm — the ideal facestock for luxury boxes, premium cartons and labels.

Woodfree Paper process: a highly purified chemical-pulp system with three-stage screening and cleaning, plus controlled surface sizing for low two-sidedness; brightness D65 ≥95%, opacity ≥90% and free of optical brighteners for notebooks, forms and office printing.

An in-house quality center with brightness, gloss, smoothness, ring-crush, burst and stiffness testers inspects every batch against GB/T 10335.1 (coated art printing paper), QB/T 3518 (cast coated paper) and GB/T 12654 (writing paper) — nothing ships unless it passes. From fibre furnish to test protocols, the quality system benchmarks China's first tier.

Fourdrinier Paper Machine
What it is: A 450,000–520,000 t/y AAA-grade paper line built around a wide, high-speed fourdrinier machine for continuous forming, pressing and drying of the paper web.
Why we do it: Large-format machines deliver higher single-line capacity and more uniform fibre distribution, while DCS control keeps basis weight and moisture stable across the deckle.
The result: Excellent formation with low cross-machine deviation, covering the full 80–350 g/m² range for premium printing, packaging and label applications.
Multi-Stage Screening System
What it is: A pulp purification train of multi-stage pressure screens and conical hydrocyclones that removes sand, shives and contaminants before the paper machine.
Why we do it: Recovered paper feedstock is inherently mixed; without purification, impurities become spots and holes that ruin printability.
The result: Markedly cleaner stock, fewer defects and less dusting — the foundation for high-brightness art paper and cast coated paper.
Low-Pulse Pulp Pumps
What it is: High-flow, low-pulse centrifugal stock pumps with enclosed piping that move fibre slurry between pulping, screening and the headbox.
Why we do it: Fibre-laden slurry demands specialised flow paths — conventional pumps clog and pulse, destabilising the jet onto the wire.
The result: Continuous, pulse-free transfer keeps the headbox jet uniform, cutting web breaks and basis-weight variation while raising machine efficiency.
Clean Energy (LNG)
What it is: An LNG-based clean energy system with cascaded heat utilisation covering the main thermal load of the dryer section.
Why we do it: Papermaking is energy-intensive; clean fuels cut sulphur, dust and carbon emissions at the source in line with dual-carbon goals.
The result: Around 10% lower comprehensive energy consumption per tonne and 98% solid-waste utilisation — economic and environmental wins together.
