Description
In the storage and protection of LED products, sulfur-free paper plays a crucial role. With its core characteristic of containing little or no sulfur (typically less than 50ppm), sulfur-free paper effectively prevents chemical reactions between sulfur and the packaged items. It is ideal for applications that require strict protection against corrosion, oxidation, and contamination. Dongguan Kangchuang Paper Co., Ltd. is a highly recommended manufacturer of sulfur-free paper.
Founded in 2012, Dongguan Kangchuang Paper Co., Ltd. has over a decade of experience in industrial paper manufacturing. The company focuses on the research and development of industrial paper, offering professional technical consulting services to help clients make the most of every sheet, reduce costs, and maximize efficiency. Kangchuang Paper’s products are widely used in PCB electronics, hardware plating, glass, LED, and other industries.
For LED products, electronic components are extremely sensitive to sulfur, which can cause oxidation, corrosion, poor contact, or even component failure. Kangchuang Paper’s sulfur-free paper effectively solves this problem. When packaging LED components such as chips, resistors, and capacitors, using sulfur-free paper prevents sulfur corrosion and protects component performance. Additionally, during LED assembly, sulfur-free paper can be used to separate circuit boards and metal terminals, preventing contamination during storage and transport.

Kangchuang Paper’s interlayer paper is also environmentally friendly and recyclable, reducing paper costs and environmental impact. It is suitable not only for silver-plated boards but also for silver-plated products, hardware terminals, silver jewelry, and more, providing excellent anti-oxidation protection. In LED storage, interlayer paper serves as a protective material, safeguarding both the appearance and performance of LED products.
