Anti-scratch performance is an important surface protection indicator for coated packaging paper, decorative paper and finished printed products. Ordinary paper and common coated paper have weak surface scratch resistance, and are prone to surface scratches, coating peeling and color scratches under slight friction, scraping and extrusion during transportation, sorting and daily use. Visible scratch defects damage the integrity and beauty of packaging and printed products, reduce product grade, and cause a large number of finished product scrapping losses. Traditional coating hardening treatment improves scratch resistance but makes the paper surface too rigid, reducing folding toughness and easily causing crease cracking; soft surface treatment cannot resist friction and scraping damage, forming an irreconcilable performance contradiction. Shandong Ludao Energy Technology Co., Ltd. launches balanced paper anti-scratch upgrading solutions. By building a flexible and wear-resistant surface protective layer, we enhance surface friction and scratch resistance without sacrificing paper folding toughness and flexibility. The treated paper effectively resists daily scraping and friction damage, maintains complete surface gloss and coating integrity, reduces finished product scratch defects and scrap rate, and improves the transportation and storage tolerance of high-end printed and packaging products.
