Technological innovation drives development—Shandong Tianyang Paper Industry has obtained a patent, contributing to the green upgrade of the specialty paper industry.

Recently, Shandong Tianyang Paper Industry Co., Ltd. has achieved another technological breakthrough: an invention patent titled “Negative-Ion Coating Specialized for Paper, Its Preparation Method, and Application” has been officially published. This technological breakthrough not only enriches the company’s intellectual property portfolio but also helps propel the specialty paper industry toward greener, more environmentally friendly, and functional development, demonstrating the company’s strong capabilities in specialty paper technology research and development.

It is reported that the newly disclosed invention patent focuses on the functional enhancement of specialty papers. The developed formaldehyde-removing negative-ion coating can be applied to the production of various types of specialty papers. Through a special coating process, this material is applied to the surface of the paper, endowing it with formaldehyde-removing and negative-ion-releasing capabilities. The coating finds wide-ranging applications in indoor decoration, office supplies, food packaging, and other scenarios, perfectly aligning with today’s consumers’ demand for green, healthy, and environmentally friendly products. The implementation of this technology further expands the application scope of Tianyang Paper’s specialty paper products, enhances their added value, and breaks through the traditional functional limitations of specialty papers.

As a national-level high-tech enterprise, Tianyang Paper Industry has always regarded technological innovation as its core development strategy. It has invested substantial resources in the improvement of specialty paper manufacturing processes and in product R&D. To date, the company holds 11 trademark registrations and 33 patent filings, and has established a comprehensive technology R&D system. It has successively launched a variety of high-end specialty paper products that align with industry trends, including environmentally friendly release liner base papers, biodegradable white kraft paper for packaging, and high-end art cardstock—products that precisely meet the industry’s development orientation toward “replacing plastics with paper” and “green, low-carbon practices.”

Currently, the specialty paper industry is accelerating its development toward “functionalization, greening, and high-endization.” Driven by both tightening environmental policies and rising consumer demand, enterprises with technological advantages and green production capabilities will enjoy greater growth opportunities. Thanks to its continuous technological innovation, Tianyang Paper has not only achieved iterative upgrades of its own products but has also provided a replicable technological roadmap for the industry’s green development. Looking ahead, the company will remain focused on niche segments within the specialty paper sector, increase R&D investment, bring more technological breakthroughs to fruition, and contribute to the high-quality, green development of Shandong’s specialty paper industry.
