Surface sizing is a key procedure to improve finished‑paper performance. Good surface‑sizing treatment can obviously enhance paper water‑resistance, reduce surface dusting and linting, and optimize printing effect, which is critical for packaging board, cultural printing paper and high‑grade carton base paper. Poor sizing effect will cause printing blur, moisture‑proof failure and high product reject rate.

Shandong Ludao Energy Technology Co., Ltd. develops and supplies multiple series of surface sizing agents suitable for different fiber raw‑material conditions. Its products can match different production speeds and sizing processes, bringing stable surface strength and water‑repellent performance for paper and board products. For mills using large proportion of recycled pulp, proper surface‑sizing formula can make up for fiber‑performance defects and reduce the dependence on high‑cost long‑fiber pulp.

Besides stable‑quality chemical supplies, the technical team of Shandong Ludao Energy Technology Co., Ltd. assists customers to adjust dosage and matching process parameters according to actual machine conditions. By optimizing surface‑sizing effects, paper mills can upgrade product grades, expand high‑end‑application scenarios and obtain better economic benefits in fierce market competition.
