Paper mill's innovation sparks success in Weifang

Shandong Wanhao Paper Industry Group in Linqu county has been recognized for its remarkable transformation, positioning it as a frontrunner in China's filter paper industry.

The company has garnered numerous accolades. Its headquarters spans 18 hectares and boasts an annual production capacity of 100,000 metric tons of machinery paper, specializing in industrial filter paper and food packaging paper.

The journey began in 1966 with the printing of textbooks and exercise books, and in 2006, the company launched its first food packaging paper production line.

The establishment of this line marked a significant step forward, requiring adherence to food-grade standards at every stage, from raw material entry to production processes. This commitment led to the creation of a diverse range of food packaging products, including coffee packaging bags and cake cup supports. Notably, Wanhao Paper became the exclusive supplier of bowl cover papers for Master Kong instant noodles throughout China.

By 2012, Wanhao Paper had expanded its product line to include coated paper and food packaging paper, which had become highly competitive fields. Following this, the company set its sights on automotive filter paper. In 2019, Wanhao Paper joined the supply chain of the German Mann+Hummel Group, the world's largest filter manufacturer, equipping automotive brands like Mercedes-Benz and BMW.
